1
00:00:00,430 --> 00:00:16,150
I think it's sort of like.

2
00:00:16,150 --> 00:00:21,490
Welcome, everybody, I'm Simon Jackman, outlets across the university with the spice sector,

3
00:00:21,490 --> 00:00:27,520
and I'm very pleased to introduce and say the head of our physics department and

4
00:00:27,520 --> 00:00:32,260
Phil Diamond is going to say a few words of welcome and then we'll get on on.

5
00:00:32,260 --> 00:00:38,160
Find out about the aliens, sir. Sir.

6
00:00:38,160 --> 00:00:45,160
So I'd like to introduce a speaker tonight and start by making a remark that this talk, of course,

7
00:00:45,160 --> 00:00:52,430
about a question that we care about finding as the search for life in the universe is fundamentally important question.

8
00:00:52,430 --> 00:00:56,470
I realise we must look at the cool does.

9
00:00:56,470 --> 00:00:59,800
It doesn't do that, but we're doing our part here tonight as well.

10
00:00:59,800 --> 00:01:08,230
As you enter this room, we were unaware of what we did and not in place of the night sky and what was not to determine with probability.

11
00:01:08,230 --> 00:01:13,990
Ninety nine point nine ninety seven is another aliens in this room.

12
00:01:13,990 --> 00:01:19,090
There are a lot of persistence. I am that point no. One. That's right.

13
00:01:19,090 --> 00:01:29,170
So so go that as the president and Chief Executive Officer and Centre Institute, which he joined in 2015.

14
00:01:29,170 --> 00:01:35,560
It's what predominantly applied technologies with over 20 years of experience over the products and up

15
00:01:35,560 --> 00:01:43,240
to three great occasions and more than a decade in X-ray and semiconductor processing technologies.

16
00:01:43,240 --> 00:01:54,610
His corporate background spans the spectrum from venture backed start-ups to Fortune 100 multinationals responsibilities ranging from R&D,

17
00:01:54,610 --> 00:02:02,140
engineering and operations to sales, marketing, product management and CEO positions.

18
00:02:02,140 --> 00:02:09,010
Most recently, he was the vice president of sales for the Colour of Inc. right hand that the company's

19
00:02:09,010 --> 00:02:16,060
penetration into optical networking of the rapidly evolving went to data centre market prices.

20
00:02:16,060 --> 00:02:23,300
That he was vice president of product management for optical fibre broadband hybrid right modules.

21
00:02:23,300 --> 00:02:28,870
Microsoft has had a variety of senior positions prior to that.

22
00:02:28,870 --> 00:02:38,530
Also waits for the technologies that select Semiconductor and X Ray to Inc., which is not quite as nice as the 10X.

23
00:02:38,530 --> 00:02:44,680
Contract also includes Sections Transit, AT&T and Bell Labs Alternate Products Business Unit,

24
00:02:44,680 --> 00:02:50,810
and he served as president at the U.S. operations and the service company Public Energy.

25
00:02:50,810 --> 00:02:58,910
It's going to be a physics from Holy Cross College and a master's in business administration from Georgetown University,

26
00:02:58,910 --> 00:03:05,960
is plus member of the Advisory Board for the Middle School of Business Administration at Georgetown

27
00:03:05,960 --> 00:03:11,630
and as a current member of the Octopus to the American and the International Astronomical Congress.

28
00:03:11,630 --> 00:03:24,770
Please join me in welcoming. OK, I believe I'm muted working.

29
00:03:24,770 --> 00:03:31,010
And let me start with a spoiler alert, there will not be an announcement tonight about any discovery.

30
00:03:31,010 --> 00:03:35,900
I'm sorry to disappoint anybody who was expecting or hoping to hear the the contrary,

31
00:03:35,900 --> 00:03:45,620
but but I do hope to have some engaging and compelling and fun information for you about the search for intelligent life, actually.

32
00:03:45,620 --> 00:03:50,270
Indeed. More broadly, the search for life in the universe and the work we do at the City Institute.

33
00:03:50,270 --> 00:04:00,140
So I hope to introduce you to the City Institute, to the research, education and outreach programmes of the institute and most importantly,

34
00:04:00,140 --> 00:04:08,420
about the power we find in interdisciplinary and multidisciplinary science, science and also the power of partnership and collaboration,

35
00:04:08,420 --> 00:04:18,170
including a collaboration we have with Oxford University and a machine learning AI programme applied to space science and also the power, if you will,

36
00:04:18,170 --> 00:04:27,050
of space and space exploration as a foundation and a platform on which to engage the public and to get the public excited about science,

37
00:04:27,050 --> 00:04:32,720
about STEM, to improve science literacy, etc. So that's the journey I hope to take you on tonight.

38
00:04:32,720 --> 00:04:37,190
I do want to start. Let's see, I guess a with with a nod to where I am.

39
00:04:37,190 --> 00:04:43,640
I mean, for me, it's such a great honour to be here at Oxford University in the Department of Physics,

40
00:04:43,640 --> 00:04:47,930
to be here at a university with such an incredible history.

41
00:04:47,930 --> 00:04:58,220
And here are just four of the hundreds or maybe thousands of incredible and amazing brains and intellects and

42
00:04:58,220 --> 00:05:05,300
individuals and personalities who have walked through the the the grounds of this incredible campus and institution.

43
00:05:05,300 --> 00:05:08,960
What's interesting here amongst this particular group of scientists,

44
00:05:08,960 --> 00:05:14,630
I did notice when kind of perusing the history of Oxford and some of the noteworthy

45
00:05:14,630 --> 00:05:19,070
graduates or attendees of the university that in the sciences in particular,

46
00:05:19,070 --> 00:05:23,000
last names beginning with H were somewhat disproportionately represented.

47
00:05:23,000 --> 00:05:29,330
So I would like to point out that if you are studying physics or the sciences at Oxford and your last name begins with H,

48
00:05:29,330 --> 00:05:34,430
we have high expectations, so please keep that in mind.

49
00:05:34,430 --> 00:05:41,000
But of course, there have been great minds, not just in the sciences. We have people like J.R.R. Tolkien, C.S. Lewis.

50
00:05:41,000 --> 00:05:47,300
I managed to sit and have a pint with with Simon at the Eagle and Child Right,

51
00:05:47,300 --> 00:05:53,300
where they sat and and discussed their their science fiction or their fantasy literature.

52
00:05:53,300 --> 00:05:59,630
And of course, Oscar Wilde is another one. Oscar Wilde studied this field called classical motivations.

53
00:05:59,630 --> 00:06:04,580
I have no idea what that means. Somebody here in the audience probably does and can enlighten me.

54
00:06:04,580 --> 00:06:11,720
But I will say that what he. We can get even with him a little bit because he had never heard of astrobiology.

55
00:06:11,720 --> 00:06:20,090
I'm quite sure. So with that, let me launch into a story about the City Institute and what we're all about.

56
00:06:20,090 --> 00:06:22,850
And it starts with a question. This is a good way to start.

57
00:06:22,850 --> 00:06:29,870
I think any discussion and the question is, do there exist many worlds or is there but a single world?

58
00:06:29,870 --> 00:06:34,280
This is one of the most noble and exalted questions in the study of nature.

59
00:06:34,280 --> 00:06:40,370
Now, this is not a quote from Stephen Hawking. It's not a quote from Carl Sagan or David Attenborough.

60
00:06:40,370 --> 00:06:44,810
It's actually a quote from this gentleman, Alberto's Magnus, who is a Jesuit priest,

61
00:06:44,810 --> 00:06:50,660
educator and philosopher in Germany Air and the in the 12th and 13th centuries.

62
00:06:50,660 --> 00:06:55,730
And so it's just an indication that this question is not new.

63
00:06:55,730 --> 00:07:04,190
This question probably dates back to the time that humans first gazed up into the sky and looked at the stars and wondered What else is out there?

64
00:07:04,190 --> 00:07:12,200
And are we alone here? And of course, it was Carl Sagan who famously said, If we're all there is what a waste of space.

65
00:07:12,200 --> 00:07:18,440
So in any case, that is really the underlying science question behind the institute.

66
00:07:18,440 --> 00:07:25,700
We're trying to find out are we alone? So a brief history of study is maybe interesting.

67
00:07:25,700 --> 00:07:30,320
It starts really the and I guess to get back to that question.

68
00:07:30,320 --> 00:07:41,630
The exciting difference between now and the time of Alberta smugness or almost any other time in history is that unlike those past times right now,

69
00:07:41,630 --> 00:07:46,370
we actually have the tools and technology to answer those questions. We've never had that before.

70
00:07:46,370 --> 00:07:54,740
So that makes a compelling case for for this work. It starts really in a publication in Nature in nineteen fifty nine from a couple of physicists at

71
00:07:54,740 --> 00:08:00,320
Cornell University who put out this paper said called searching for interstellar communication.

72
00:08:00,320 --> 00:08:05,450
So this was by Kerkorian Morrison. And it really put forth the idea.

73
00:08:05,450 --> 00:08:10,850
For the first time of it was let's be honest and anthropocentric idea,

74
00:08:10,850 --> 00:08:16,580
because it sort of put human motivations and behavioural characteristics on the part of alien intelligence.

75
00:08:16,580 --> 00:08:20,150
But it said that if there are alien intelligence out there,

76
00:08:20,150 --> 00:08:25,550
if they have developed technologies that include the ability to manipulate the electromagnetic

77
00:08:25,550 --> 00:08:29,570
spectrum and make their presence known either intentionally or unintentionally,

78
00:08:29,570 --> 00:08:34,410
maybe we can listen in and find them. So it's really an exciting and interesting.

79
00:08:34,410 --> 00:08:43,220
And as you can probably imagine, somewhat controversial paper at the time of publication, but it really is the birth of all city endeavours.

80
00:08:43,220 --> 00:08:47,750
And then in 1959, just a couple of months later,

81
00:08:47,750 --> 00:08:57,060
Harlow Shapely from Harvard University actually speculated that as many as 100 million worlds might exist where life has been forged by evolution.

82
00:08:57,060 --> 00:09:04,970
That's a pretty bold statement. Now, turns out that Harvard, if you if you look at Avi Loeb and the muumuu of incidents we had recently in his paper,

83
00:09:04,970 --> 00:09:12,890
speculating that it's possible that could be an alien spacecraft. Harvard is maybe not unfamiliar with putting out this sort of speculative ideas,

84
00:09:12,890 --> 00:09:20,030
but but this was a really interesting proposition on the part of this astronomer at Harvard.

85
00:09:20,030 --> 00:09:25,730
And then in July of 1960, from actually from April to July of 1960,

86
00:09:25,730 --> 00:09:29,930
Frank Drake of Drake Equation famous everybody here familiar with the Drake Equation.

87
00:09:29,930 --> 00:09:34,790
Anybody not familiar with Drake Equation. The doors are over here. If that's the case now.

88
00:09:34,790 --> 00:09:39,500
So Frank Drake launched Project Osma at the 25 metre dish,

89
00:09:39,500 --> 00:09:45,830
which at the time was the large dish at the National Astronomy Radio Observatory in Green Bank, West Virginia.

90
00:09:45,830 --> 00:09:56,420
So that was the first ever city endeavour using radio astronomy or radio telescopes to listen for signals in in deep space.

91
00:09:56,420 --> 00:10:04,880
The a year later, in 1961, a meeting was held at Green Bank that was called for by NASA.

92
00:10:04,880 --> 00:10:13,010
So Nasser brought together a bunch of scientists, including Frank Drake, Carl Sagan and about a dozen others to address the question.

93
00:10:13,010 --> 00:10:21,800
From a scientific point of view, is there scientific merit to the idea of looking or searching for extraterrestrial intelligence?

94
00:10:21,800 --> 00:10:26,060
Is there legitimacy in such an endeavour and undertaking?

95
00:10:26,060 --> 00:10:29,960
So Frank, the group that gathered,

96
00:10:29,960 --> 00:10:39,260
called themselves the order of the dolphin and the attendees included this this kind of interesting range and cross-section of individuals.

97
00:10:39,260 --> 00:10:48,080
But the result of as a result of that meeting, Frank decided, like anybody who knows how to run a meeting, we need an agenda.

98
00:10:48,080 --> 00:10:51,410
I hate going to meetings where there's no agenda, Frank said.

99
00:10:51,410 --> 00:10:55,880
We need an agenda if we're going to have this discussion. And as a result of thinking that through.

100
00:10:55,880 --> 00:10:59,840
He started writing down the agenda items that he thought should be discussed.

101
00:10:59,840 --> 00:11:03,120
Things like, Well, what are the what's the rate of star formation?

102
00:11:03,120 --> 00:11:08,270
How many stars have planets, how many planets might be in the habitable zone of their star,

103
00:11:08,270 --> 00:11:12,980
how many planets that are in the habitable zone might go on to develop life and so on?

104
00:11:12,980 --> 00:11:18,050
And he realised as he started putting these things together, he had a relationship that was unfolding.

105
00:11:18,050 --> 00:11:24,140
He had a formula or an equation which is now known as the Drake Equation, and that is here.

106
00:11:24,140 --> 00:11:34,130
So again, as as a quick review, we have end, which might be the number of detectable civilisations where technology has evolved,

107
00:11:34,130 --> 00:11:42,300
is a function of the rate of star formation or star birth at times the fraction of those stars that might have planets around them.

108
00:11:42,300 --> 00:11:45,380
Back in 1961, we didn't know the answer to that question.

109
00:11:45,380 --> 00:11:53,510
The number or portion of those planets that might be rocky Earth like planets in the habitable zone of their host star,

110
00:11:53,510 --> 00:11:58,400
the fraction of those planets that might go on to develop life sabel,

111
00:11:58,400 --> 00:12:05,240
those that go on to develop life, the fraction of those where the conditions are right for evolutionary forces and processes to take hold,

112
00:12:05,240 --> 00:12:12,950
such that that intelligence evolves and emerges times the fraction of those planets where intelligence and

113
00:12:12,950 --> 00:12:19,550
complexity evolves and emerges that might have communications capability or might have developed technology,

114
00:12:19,550 --> 00:12:25,680
essentially the ability to manipulate the electoral map. That spectrum in a way that might be detectable from great distances.

115
00:12:25,680 --> 00:12:31,770
That's if subsea time's the last. And my favourite variable in the Drake Equation L.

116
00:12:31,770 --> 00:12:40,260
How long do technological civilisations last? And that is not just a matter of how long do they survive.

117
00:12:40,260 --> 00:12:48,120
It's not necessarily that the endpoint might be the extinction of the civilisation, but rather how long might a civilisation remain detectable?

118
00:12:48,120 --> 00:12:54,570
Our own civilisation on this planet is arguably going a little bit dark over time as more of our communications,

119
00:12:54,570 --> 00:12:57,390
including things like television and music,

120
00:12:57,390 --> 00:13:05,670
et cetera, is done over the internet, which is in turn done over optical fibres, which do not emit signals that could be seen from from space.

121
00:13:05,670 --> 00:13:11,850
So we're going dark. We're going to need a little bit quieter. There's also the issue that as a result of the gift of technology,

122
00:13:11,850 --> 00:13:17,880
we've imposed upon ourselves some interesting challenges that we need to overcome if we're going to survive long term.

123
00:13:17,880 --> 00:13:25,770
And so it may be as well that civilisations could get to a point where they emerge into a

124
00:13:25,770 --> 00:13:30,210
state or evolve into a state where they are no longer deploying or dependent on technology.

125
00:13:30,210 --> 00:13:34,440
They're perhaps back into a more symbiotic relationship with their environment,

126
00:13:34,440 --> 00:13:39,090
balance with the ability of that environment to generate resources, etc. so they go dark.

127
00:13:39,090 --> 00:13:45,660
In any case, L is is kind of an appealing and intriguing variable in its own right.

128
00:13:45,660 --> 00:13:49,560
There are some noteworthy anniversaries happening just this year, as it turns out.

129
00:13:49,560 --> 00:13:58,770
So July 1969, of course, the Apollo 11 moon landing 50 years ago, coming up very soon in September 1959, so 60 years ago,

130
00:13:58,770 --> 00:14:08,460
was that Gakonis and Morrison paper, which is really something of of, ah, an important anniversary for the institute and for the science we do.

131
00:14:08,460 --> 00:14:15,090
In June of nineteen forty years ago or so, in 1949 or 70 years ago,

132
00:14:15,090 --> 00:14:21,780
George Orwell published his famous book 1984, saying, OK, well, what is 1984 have to do with any of this?

133
00:14:21,780 --> 00:14:30,720
Well, 1984 was the birth of the said.He Institute. So Big Brother, as predicted by George Orwell in 1984, didn't quite emerge,

134
00:14:30,720 --> 00:14:35,670
although it looks like it's coming along now in terms of cameras everywhere watching what we're doing.

135
00:14:35,670 --> 00:14:43,920
But the City Institute was founded in 1984. Thirty five years ago this year, so an introduction to the City Institute.

136
00:14:43,920 --> 00:14:46,680
Our mission statement, quite simply, is to explore,

137
00:14:46,680 --> 00:14:52,650
understand and explain the nature and origins of life in the universe and the evolution of intelligence.

138
00:14:52,650 --> 00:14:59,460
And that last statement is really important because it differentiates us from NASA, whose interest in astrobiology,

139
00:14:59,460 --> 00:15:04,290
while legitimate, sort of terminate at the discovery of microbes and microbial life.

140
00:15:04,290 --> 00:15:11,490
So we're interested in. So what happens next and what are the conditions under which microbial or very basic life might evolve

141
00:15:11,490 --> 00:15:15,780
into something a little bit more interesting that we might theoretically have a conversation with?

142
00:15:15,780 --> 00:15:20,580
For example, so in a sense, we're boldly going where no other institute goes before.

143
00:15:20,580 --> 00:15:23,100
We're the only institute in the world, to my knowledge,

144
00:15:23,100 --> 00:15:30,180
whose singular mission and purpose is this search for extraterrestrial life from the microbial level on up.

145
00:15:30,180 --> 00:15:35,100
So that's the sole purpose and science mission of the institute.

146
00:15:35,100 --> 00:15:40,770
We're all here simply to answer this question Are we alone?

147
00:15:40,770 --> 00:15:47,820
So what do we do at the institute? Fundamentally, we're working to understand the origins of life starting at its most basic level from the

148
00:15:47,820 --> 00:15:53,220
formation of molecules and prebiotic chemistry to the evolution of more complex organisms,

149
00:15:53,220 --> 00:15:55,230
sentient beings and ultimately intelligence.

150
00:15:55,230 --> 00:16:07,890
So we're really on a journey to try to understand how we went from the pre biological sort of current galactically structured universe.

151
00:16:07,890 --> 00:16:12,690
How did we go from the early cosmology following the Big Bang through to the onset of

152
00:16:12,690 --> 00:16:18,330
chemistry and this transition from chemistry and prebiotic chemistry into biology?

153
00:16:18,330 --> 00:16:23,280
And ultimately, how did biology evolve, at least on this planet, to give us philosophy?

154
00:16:23,280 --> 00:16:30,150
That's the journey and mission of the institute. We have our own sort of giants that we we stand on the shoulders of at the institute.

155
00:16:30,150 --> 00:16:35,160
Frank Drake himself was one of the founders. Frank is now 88 years old.

156
00:16:35,160 --> 00:16:40,320
He's still around. He still comes out of the institute about once a week, and it's always fun for him to come into the institute.

157
00:16:40,320 --> 00:16:44,190
When I happen to be giving a tour and happening to be standing by the Drake Equation,

158
00:16:44,190 --> 00:16:49,500
which is in the front lobby and happened to be describing it and somebody asks me, was frank still around?

159
00:16:49,500 --> 00:16:52,800
And he walks through the door at that moment, and that's really good.

160
00:16:52,800 --> 00:16:57,750
I've told him that that happened once and I've told him I want to have him sitting at a desk outside the

161
00:16:57,750 --> 00:17:03,060
door where I push a button and he comes in on cue because it was it was so brilliant when that happened.

162
00:17:03,060 --> 00:17:07,500
Carl Sagan was another one of the original founders of the institute, as was Charles Townes.

163
00:17:07,500 --> 00:17:11,340
Charles Townes is a Nobel laureate who was the inventor of the laser and the laser.

164
00:17:11,340 --> 00:17:17,340
So everything that has to do with lasers, whether it's surgery or communications or supermarket scanners,

165
00:17:17,340 --> 00:17:21,840
ultimately traces back to the work of Charlie Townes and then Jill Tarter,

166
00:17:21,840 --> 00:17:26,370
who is a woman astronomer at a time when women weren't even allowed in observatories.

167
00:17:26,370 --> 00:17:31,740
So talk about a strong character and a brave character and a brilliant, brilliant mind.

168
00:17:31,740 --> 00:17:35,430
Anybody see the movie? Contact most everybody or a lot of people?

169
00:17:35,430 --> 00:17:45,270
If you haven't, I recommend it. It's still as as interesting and fascinating today as it was 25 years ago, or 20, at least when it first came out.

170
00:17:45,270 --> 00:17:50,070
But Jill, being a colleague and contemporary of Carl Sagan's from Cornell, as was Frank.

171
00:17:50,070 --> 00:17:54,600
So Frank and Carl and Jill all came out of Cornell Astronomy and Astrophysics.

172
00:17:54,600 --> 00:17:58,770
Jill was the inspiration for the character played by Jodie Foster in that movie.

173
00:17:58,770 --> 00:18:02,550
I like to point out that she is, you know, the movie.

174
00:18:02,550 --> 00:18:06,810
The first half of the movie is based on Jill's life, not the second half, but in any case.

175
00:18:06,810 --> 00:18:10,560
So Jill is is another one of our our founders.

176
00:18:10,560 --> 00:18:15,960
In 1984, when the institute was founded, there was four trustees, one principal investigator that was Jill.

177
00:18:15,960 --> 00:18:23,880
And as of 2019, we have 16 trustees. We also have a science advisory board that includes, amongst others, Brother Guy console.log.

178
00:18:23,880 --> 00:18:29,100
Now, who's the astronomer for the Vatican? And a lot of other notables on the science board.

179
00:18:29,100 --> 00:18:35,700
We have 90 scientists and and principal investigators. They represent 23 different academic research disciplines.

180
00:18:35,700 --> 00:18:44,460
We have them organised into six research divisions. We also have 70 affiliates or affiliates are individuals who write grant proposals under the.

181
00:18:44,460 --> 00:18:50,310
And through the Senate Study Institute to submit to NASA or other funding agencies.

182
00:18:50,310 --> 00:18:54,420
We have three primary activity centres, which I'll describe in a moment.

183
00:18:54,420 --> 00:19:01,920
And in addition to the research, which is our primary function, we do have 28 of the other staff who are involved in things like education programmes,

184
00:19:01,920 --> 00:19:06,420
outreach and communications, grant proposal writing and the middle and, of course,

185
00:19:06,420 --> 00:19:10,560
administrative and support staff who are equally important members of the team.

186
00:19:10,560 --> 00:19:15,510
So our primary structure around these three centres that I mentioned before is research,

187
00:19:15,510 --> 00:19:22,380
which we say is to explore it's education to inspire and its outreach to engage.

188
00:19:22,380 --> 00:19:27,990
And the engagement of the public is something we take very seriously as serious as our science.

189
00:19:27,990 --> 00:19:33,090
We are a principal science partner to NASA, where one of the top 100 contractors to NASA.

190
00:19:33,090 --> 00:19:38,370
I will point out that the difference between sort of the bottom part of the 100 and the top part is really big.

191
00:19:38,370 --> 00:19:45,180
So we're nowhere near the size of Northrop Grumman or or Boeing, but but we are at least in that top 100.

192
00:19:45,180 --> 00:19:50,280
We also get funding from U.S. Geological Survey from the National Science Foundation,

193
00:19:50,280 --> 00:19:56,430
Space Telescope Institute, National Institute of Health, the National Oceanic and Atmospheric Administration.

194
00:19:56,430 --> 00:20:05,370
But the bulk of our of our funding comes from NASA. As such, we are, by definition, a publicly funded, taxpayer funded enterprise.

195
00:20:05,370 --> 00:20:13,050
And as a result, we have a responsibility and a duty to give back and share with the public the work and the science we do at the institute.

196
00:20:13,050 --> 00:20:16,170
So that's why outreach and public engagement is so important.

197
00:20:16,170 --> 00:20:25,770
I think in addition to its opportunity to hopefully inspire and engage the public, it's it's a it's an actual duty and responsibility.

198
00:20:25,770 --> 00:20:31,530
The Carl Sagan Centre for Outreach, sorry for research, is structured into six areas six domains,

199
00:20:31,530 --> 00:20:40,100
so astronomy and astrophysics, exoplanets, climate and geoscience, planetary exploration, which is really about.

200
00:20:40,100 --> 00:20:46,640
A study of our own solar system and how do we explore the planets and moons of our own solar system?

201
00:20:46,640 --> 00:20:53,690
Astrobiology, which is, on the one hand, an envelope expression which could be used to describe all of the work of the institute.

202
00:20:53,690 --> 00:21:00,530
But in this case, I'm referring to astrobiology in terms of the study of what we call extremophiles or extreme biology life in extreme

203
00:21:00,530 --> 00:21:08,150
environments and how that research informs us in terms of the science we undertake for study endeavours more broadly.

204
00:21:08,150 --> 00:21:10,040
And then last but certainly not least,

205
00:21:10,040 --> 00:21:18,050
the namesake activity our study programmes in which we leverage both the optical and the radio domain to do steady work.

206
00:21:18,050 --> 00:21:23,360
I will say that in the area of exoplanets in particular, we've had a lot of engagement.

207
00:21:23,360 --> 00:21:29,570
We had members of the science team of a programme called the PI, the Gemini Planetary Imager,

208
00:21:29,570 --> 00:21:33,920
which was using the eight metre telescope Gemini Telescope in Chile,

209
00:21:33,920 --> 00:21:40,670
which took the first ever photograph actual image of a planet around another star.

210
00:21:40,670 --> 00:21:44,900
And that was done in 2015, and that was done using technology called adaptive optics,

211
00:21:44,900 --> 00:21:50,420
which compensated for the Earth's distortion of the atmosphere and also a coronagraph

212
00:21:50,420 --> 00:21:55,460
which blocked the light of the star so that you could image something close to that star.

213
00:21:55,460 --> 00:22:02,060
A very important technology. So leveraging those two technologies, we took the first ever photograph of a planet around another star,

214
00:22:02,060 --> 00:22:08,600
and it's actually quite a moving thing to see when you realise what it is you're looking at, because we didn't even know they existed.

215
00:22:08,600 --> 00:22:11,270
Not too many years ago.

216
00:22:11,270 --> 00:22:18,530
We also were very active in exoplanets, and I'm going to talk a little bit more about this particular area in terms of the Kepler mission,

217
00:22:18,530 --> 00:22:23,510
which was the Planet Hunter Space Telescope that NASA launched some years ago.

218
00:22:23,510 --> 00:22:29,210
The mission just came to an end, although the science continues. So we'll talk a little bit more about that in a moment.

219
00:22:29,210 --> 00:22:36,310
In the meantime, back to the Drake Equation, I think one of the things that the Drake Equation evolved to represent,

220
00:22:36,310 --> 00:22:43,100
in addition to this interesting way of perhaps speculating on the number of intelligent and technological species,

221
00:22:43,100 --> 00:22:50,180
it's actually a roadmap for astrobiology that wasn't necessarily what Frank had in mind when he put this together.

222
00:22:50,180 --> 00:22:57,500
But in a way, this really takes all the elements of science that we need to consider when we're considering the question of life in the universe.

223
00:22:57,500 --> 00:23:04,670
And so we actually map the research of the institute and the divisions of research to the various variables of the Drake Equation.

224
00:23:04,670 --> 00:23:09,800
So we have astronomy and astrophysics which address things like star formation and planet formation.

225
00:23:09,800 --> 00:23:15,770
We have exoplanets which address things like what fraction of stars have planets and how does that happen?

226
00:23:15,770 --> 00:23:21,500
And then what portion of those planets might be in the habitable zone might be Earth like planets.

227
00:23:21,500 --> 00:23:29,990
And then there is planetary exploration, which addresses both of those same variables, as well as f sabel what fraction of planets might have life?

228
00:23:29,990 --> 00:23:35,240
We still think, and I think there's a reasonable case to be made for the idea that Mars may,

229
00:23:35,240 --> 00:23:40,160
may harbour life, not on the surface, almost certainly, but maybe even a metre below.

230
00:23:40,160 --> 00:23:46,490
Lots of good evidence to suggest that there is climate in geoscience, climate and geology.

231
00:23:46,490 --> 00:23:53,900
I mean, biology and climate and geology of things like volcanology, earthquakes.

232
00:23:53,900 --> 00:24:00,230
All of these mechanisms are intertwined and interrelated in terms of what does habitability mean?

233
00:24:00,230 --> 00:24:06,170
How does life start? How do nutrients and life and prebiotics get distributed in a planetary environment, et cetera?

234
00:24:06,170 --> 00:24:12,320
So climate and geoscience are quite interesting. Climate is another area where we can look at to say,

235
00:24:12,320 --> 00:24:18,890
Is it possible that biology creates a signature in climate atmospheres that we could detect from a great distance?

236
00:24:18,890 --> 00:24:21,350
And we're about to embark on a mission.

237
00:24:21,350 --> 00:24:28,880
The James Webb Space Telescope, everybody, please cross your fingers that that's going to launch when they say it is, but that is going to, I think,

238
00:24:28,880 --> 00:24:35,090
transform space science and exploration and questions like that that we are pursuing

239
00:24:35,090 --> 00:24:39,920
in a similar manner to the way that Hubble transformed astronomy and astrophysics.

240
00:24:39,920 --> 00:24:46,790
I think it's going to be an order of magnitude more profound in terms of what we learn and observe from James Webb once that gets up there.

241
00:24:46,790 --> 00:24:52,520
But climate again, is is an important ingredient in this question of life in the universe.

242
00:24:52,520 --> 00:25:01,400
Astrobiology again addressing the questions of habitable zone planets, indeed the evolution or the development of life on those planets.

243
00:25:01,400 --> 00:25:07,040
That's where those two solid lines are kind of where NASA's interest in astrobiology comes to an end.

244
00:25:07,040 --> 00:25:12,320
At the institute, we extend that study of astrobiology to include how does intelligence happen,

245
00:25:12,320 --> 00:25:17,930
how does complexity take place, and what are the conditions under which that might happen?

246
00:25:17,930 --> 00:25:25,820
And ultimately, what what are the odds of technological civilisations emerging from those evolutionary processes?

247
00:25:25,820 --> 00:25:29,990
And then, of course, our sweaty work is focussed on f sub C,

248
00:25:29,990 --> 00:25:40,160
that fraction of life bearing planets where technology does emerge and also that that interesting variable L and I will say as well that.

249
00:25:40,160 --> 00:25:49,880
When we talk about the emergence of technology and humankind's own position along that spectra, we're only 100 years into our technology phase,

250
00:25:49,880 --> 00:25:56,120
so we kind of defined technology as the onset of the manipulation of the electromagnetic spectrum,

251
00:25:56,120 --> 00:26:00,200
specifically the invention of the radio, which is, you know, more or less 100 years ago.

252
00:26:00,200 --> 00:26:06,290
So humankind is really 100 years into our technology phase, which means we're in our infancy.

253
00:26:06,290 --> 00:26:11,840
I think it's extraordinary to look back and think what's been achieved and learnt and understood it in 100 years.

254
00:26:11,840 --> 00:26:14,510
What are the next hundred years hold in store for us?

255
00:26:14,510 --> 00:26:20,720
I think, you know, it's a it's a nonlinear function of knowledge and information that will just continue.

256
00:26:20,720 --> 00:26:24,110
We're science partner to to NASA on a variety of missions.

257
00:26:24,110 --> 00:26:31,670
We've been involved in almost every non manned or personal mission that NASA has ever flown since the institute came into being,

258
00:26:31,670 --> 00:26:33,650
including the Cassini mission.

259
00:26:33,650 --> 00:26:45,680
We had scientists who using the the Cassini data, wrote the first papers on driving the geology and structure of the moon of Saturn Enceladus,

260
00:26:45,680 --> 00:26:52,850
which is compelling and interesting as a possible harbour of life below its icy outer surface.

261
00:26:52,850 --> 00:26:57,290
That particular moon has an odd wobble as it goes around Saturn.

262
00:26:57,290 --> 00:27:06,620
And scientists had been trying to derive the geological structure that would would result in that funny orbital dynamic.

263
00:27:06,620 --> 00:27:13,640
And so our team looked at the data and modelled a moon in which you have an icy outer crust and a global

264
00:27:13,640 --> 00:27:19,520
ocean underneath that and a solid core and no physical contact between the solid core and the outer crust.

265
00:27:19,520 --> 00:27:27,410
And they then applied that model, and it absolutely nailed the observed data and behaviour of the planet.

266
00:27:27,410 --> 00:27:30,230
So or the Moon rather? So interesting work there.

267
00:27:30,230 --> 00:27:38,630
We've had scientists at the institute studying so-called propellers or proto moons sort of getting born, if you will,

268
00:27:38,630 --> 00:27:46,670
in the ring system of Saturn and the propellers refers to sort of the way that material leaves behind as it begins to retreat in Saturn's rings.

269
00:27:46,670 --> 00:27:55,790
And another scientists looked at the Cassini data and came to the conclusion that the rings of Saturn may only be about 150 million years old,

270
00:27:55,790 --> 00:28:03,170
which is an interesting finding and discovery on a on a planetary system that's, you know, four point two to five billion years old.

271
00:28:03,170 --> 00:28:12,620
So some interesting aspects of that Kepler and K2 mission I'll talk about in a little bit more detail and come back to that New Horizons.

272
00:28:12,620 --> 00:28:20,390
The scientists from the City Institute, Mark Showalter, was part of the New Horizons team, leading what's called the Hazard Avoidance Team.

273
00:28:20,390 --> 00:28:24,440
The Hazard Avoidance team has the important responsibility of making sure there's nothing in the way,

274
00:28:24,440 --> 00:28:32,450
as the spacecraft hurtles at forty thousand miles an hour towards Pluto and now more recently towards the Kuiper Belt object MU69.

275
00:28:32,450 --> 00:28:42,170
And as a result of the work that they were doing in in that preparation for the flyby back in July of 2015,

276
00:28:42,170 --> 00:28:49,370
they started by using the Hubble Space Telescope, and then they began to be able to use the onboard cameras and systems of the spacecraft.

277
00:28:49,370 --> 00:28:57,290
And as a result of that, two new moons of Pluto were discovered that had been never known before, which became known as Kerberos and Styx.

278
00:28:57,290 --> 00:29:02,480
And so they are attributed to Mark Showalter from the institute. And to to the team.

279
00:29:02,480 --> 00:29:07,790
A funny side story is that the band sticks for the young folks who may not have heard of them.

280
00:29:07,790 --> 00:29:15,170
But my generation, we've heard of that, that band, they thought, Oh, well, they the NASA has just named a moon after our band.

281
00:29:15,170 --> 00:29:24,080
How cool. Let's go show up. And so they came to the Applied Physics Lab at Johns Hopkins University, where that the New Horizons team was based,

282
00:29:24,080 --> 00:29:28,190
and they wanted to get their picture taken with the guy who discovered their moon.

283
00:29:28,190 --> 00:29:30,830
And so for about two weeks on the NASA's homepage,

284
00:29:30,830 --> 00:29:36,320
there was a picture Mark Showalter with the band Styx on either side, if you could still find it online.

285
00:29:36,320 --> 00:29:42,890
It's really quite cute, and Mark keeps a copy of it in his office, and he likes to hold it up and show people and ask them to spot the one.

286
00:29:42,890 --> 00:29:50,600
That's different. So it's good fun. But in any case, so, so the The New Horizons mission was interesting.

287
00:29:50,600 --> 00:29:59,570
I also like to remind people how amazing some of these missions are when you talk about the investment of personal capital and time as a scientist.

288
00:29:59,570 --> 00:30:05,240
So New Horizons launched in 2006.

289
00:30:05,240 --> 00:30:09,500
I don't know how many years, but probably at least a decade had gone by in terms of mission,

290
00:30:09,500 --> 00:30:14,360
concept and planning, spacecraft design, development, manufacture, cetera.

291
00:30:14,360 --> 00:30:23,540
And then the launch 2006. It takes nine years for that spacecraft to reach Pluto, and the science took place in seven minutes.

292
00:30:23,540 --> 00:30:33,500
So it's a seven minute flyby after nine years and billions of miles of space travel at forty thousand miles an hour and then seven months of data.

293
00:30:33,500 --> 00:30:39,620
Download a data transfer because it takes that long to transfer all the data back to Earth because the data pipeline is rather.

294
00:30:39,620 --> 00:30:42,440
Ltd. They're not using fibre optics, needless to say.

295
00:30:42,440 --> 00:30:50,780
So a little bit of constraint there, but I just think that's representative of sort of the scientific bravery of some of these missions.

296
00:30:50,780 --> 00:30:56,990
Staking your career on a seven minute flyby while waiting about 15 years for it to happen is pretty interesting stuff.

297
00:30:56,990 --> 00:31:00,980
OSIRIS-REx is an interesting mission. This is a capture and return mission.

298
00:31:00,980 --> 00:31:08,660
It's the first such mission for NASA, other than the first trips to the Moon, where they brought back lunar samples.

299
00:31:08,660 --> 00:31:15,950
But it's the first robotic mission to an object in space where the idea is to capture material and bring it back.

300
00:31:15,950 --> 00:31:22,430
It is not the first time for humankind to do this. The Japanese have done this with an asteroid already once.

301
00:31:22,430 --> 00:31:28,520
But where we've gone to OSIRIS-REx, that spacecraft arrived in December of last year.

302
00:31:28,520 --> 00:31:38,180
It will orbit this about five hundred metre spheroid asteroid called Bennu for a couple of years, mapping it and analysing it and studying it.

303
00:31:38,180 --> 00:31:46,730
And then it will go down to the surface. You can see in this photograph or not a photograph of this animation or cartoon,

304
00:31:46,730 --> 00:31:55,520
a picture of the spacecraft and you see this harm called the TAGSAM or the Touch-And-Go Sample ARM Sample Retrieval ARM coming down.

305
00:31:55,520 --> 00:32:02,120
So the spacecraft will hover very close to the surface of the asteroid. Get closer and closer until that arm can touch down.

306
00:32:02,120 --> 00:32:09,380
Kind of an old fashioned sort of like a car filter, air filter and a carburettor will actually be on the surface.

307
00:32:09,380 --> 00:32:15,680
They'll suck regolith and material through that filter captured in the filter that will then get popped into a backpack,

308
00:32:15,680 --> 00:32:24,890
which you can sort of see as that little dome on the top of the spacecraft. The spacecraft will then return to Earth in 2023 and in September of 2023.

309
00:32:24,890 --> 00:32:29,240
If all goes well, I think around about the 14th and possibly around 2:00 in the afternoon,

310
00:32:29,240 --> 00:32:35,210
it will eject that backpack and it will be parachuted down into Utah for retrieval.

311
00:32:35,210 --> 00:32:42,170
We have two scientists on that team, one who's waiting for the material to arrive in 2023 to analyse it,

312
00:32:42,170 --> 00:32:46,760
and we have another one who was called upon because Bennu is doing something interesting.

313
00:32:46,760 --> 00:32:52,430
It's ejecting material into space and scientists don't know how that's happening or why that's happening, necessarily.

314
00:32:52,430 --> 00:32:58,610
And so this particular scientist has a global camera system that is actually able

315
00:32:58,610 --> 00:33:04,160
to look at at meteorites and trace them back to their origin of space object,

316
00:33:04,160 --> 00:33:10,640
which could be a comet in this case, because the orbit of Bennu and the orbit of Earth overlap and intersect.

317
00:33:10,640 --> 00:33:18,230
The idea is if this object is putting material out on a regular basis at those times where our orbital paths cross,

318
00:33:18,230 --> 00:33:23,060
we might be able to capture some of that material and and learn some interesting things about it.

319
00:33:23,060 --> 00:33:31,190
So and understand how and why it's happening in the first place. Back to Kepler, just briefly, that one launched in March of 2009.

320
00:33:31,190 --> 00:33:39,140
Bill Borucki from NASA Ames was the principal investigator on that took him five tries at NASA to get that project funded.

321
00:33:39,140 --> 00:33:44,990
I personally believe that this is one of the most profound missions in NASA's history in terms of science.

322
00:33:44,990 --> 00:33:51,260
And the reason I say that is because, unlike other NASA programmes and spacecraft which have done amazing science,

323
00:33:51,260 --> 00:33:55,010
captured incredible images, taught us all kinds of interesting things.

324
00:33:55,010 --> 00:34:01,040
The Kepler mission has hurt permanently and profoundly transformed our understanding

325
00:34:01,040 --> 00:34:05,450
of our place in the universe because it taught us that planets are everywhere.

326
00:34:05,450 --> 00:34:11,090
And until Kepler came along, we didn't know that although many in the scientific community, I think,

327
00:34:11,090 --> 00:34:19,550
had a pretty good and accurate understanding of planet formation and a pretty good idea that probably planets are more common than we might think.

328
00:34:19,550 --> 00:34:23,990
The Kepler mission taught us that essentially every star in the sky, statistically speaking,

329
00:34:23,990 --> 00:34:27,320
has one or more planets around it, and it taught us more than that.

330
00:34:27,320 --> 00:34:32,900
We're able to look at the orbital periods. We're able to see how far those planets are from the Sun,

331
00:34:32,900 --> 00:34:38,150
from their star and therefore which what portion of them might be in the habitable zone of that star.

332
00:34:38,150 --> 00:34:47,480
We were able to kind of determine their size, and what we realised as a result is the number of planets in the habitable zone of their host star.

333
00:34:47,480 --> 00:34:54,440
Just in our galaxy that are rocky sort of Earth like planets is estimated to be between 10 and 60 billion.

334
00:34:54,440 --> 00:35:01,730
So that's a lot of candidate possibilities for something interesting, like life to have happened or to have taken place.

335
00:35:01,730 --> 00:35:07,370
So I think Kepler's marvellous instrument, this is kind of how it worked.

336
00:35:07,370 --> 00:35:15,050
This is an animation of of the light curves, which are the type of data that Kepler is is picking up.

337
00:35:15,050 --> 00:35:25,730
So Kepler, first for three years, was staring at a piece of sky in the constellation Cassiopeia if you held up your your fist at about arm's length.

338
00:35:25,730 --> 00:35:30,290
That little circle would be about the size of the section of Sky being stared at.

339
00:35:30,290 --> 00:35:35,420
It's about 200000 stars being looked at for constantly for a three year period.

340
00:35:35,420 --> 00:35:39,640
And what it was doing was looking for these transits or when a planet.

341
00:35:39,640 --> 00:35:47,410
Would go between our point of view and the star and therefore slightly dim the light of that star enough to be measured.

342
00:35:47,410 --> 00:35:56,650
Now this is a great exaggeration in this animation. The light curves do not dip that much, but an Earth like planet around a Sun like star,

343
00:35:56,650 --> 00:36:00,580
for example, might only dim the light of that star by one part in 10000.

344
00:36:00,580 --> 00:36:06,730
And when you're talking about point sources of light on a on a large sensor array, that's a very, very sensitive measurement.

345
00:36:06,730 --> 00:36:11,740
But the instrument was capable of doing that, and it discovered a lot of planets.

346
00:36:11,740 --> 00:36:18,730
So that's the data set as of the end of 2017 of candidate planets coming from the Kepler system.

347
00:36:18,730 --> 00:36:25,240
Those are in yellow. The bluish and greyish planets were discovered by other techniques, such as radial velocity method.

348
00:36:25,240 --> 00:36:29,890
They tend to be good at finding the larger gas giant planets, but not the smaller ones.

349
00:36:29,890 --> 00:36:38,560
The scale on the y axis is the radius of the planet, and the x axis is the orbital period.

350
00:36:38,560 --> 00:36:41,830
So Earth like planets would be in sort of the lower right hand side.

351
00:36:41,830 --> 00:36:50,290
Interestingly, not a lot of Earth like planets with one year orbital periods, although some but but a lot with much shorter periods.

352
00:36:50,290 --> 00:36:54,550
And now we have the TESS mission, which is the follow on mission.

353
00:36:54,550 --> 00:36:59,200
It's the Transiting Exoplanet Survey Satellite and that's mapping the entire sky.

354
00:36:59,200 --> 00:37:02,890
It will be looking at any particular field of view for a much shorter period of time.

355
00:37:02,890 --> 00:37:11,590
But the idea is to map the entire sky to look at stars closer by and to give us more and better information about exoplanets.

356
00:37:11,590 --> 00:37:18,760
And this, in turn, means that now we know where to look in terms of setting.

357
00:37:18,760 --> 00:37:23,950
So Ceti becomes a more purposeful endeavour where you have targets of interest instead

358
00:37:23,950 --> 00:37:28,720
of just random points in the sky to look at a random types of stars to look at.

359
00:37:28,720 --> 00:37:36,640
Interestingly enough, although the Kepler mission came to an end officially last year, the Kepler space telescope is still making news.

360
00:37:36,640 --> 00:37:41,800
So a team at University of Hawaii just published a paper in March,

361
00:37:41,800 --> 00:37:51,010
so a few weeks back confirming the very first exoplanet candidate that was in the Kepler dataset a full 10 years after launch.

362
00:37:51,010 --> 00:37:58,300
So really interesting. And as is so often the case, data collection is one thing, data analysis is another,

363
00:37:58,300 --> 00:38:06,790
and it gets back as well to how we handle all the data we're amassing on an increasing rapid basis.

364
00:38:06,790 --> 00:38:09,730
But but the data is there to still be mined,

365
00:38:09,730 --> 00:38:19,750
and the results so far as a mission update again are 4000 confirmed exoplanets in the Kepler field and over 3000 planetary systems.

366
00:38:19,750 --> 00:38:27,610
And as I mentioned before, between 10 and 60 billion candidate planets in the habitable zone of their host star.

367
00:38:27,610 --> 00:38:32,980
I talked a little bit about New Horizons missions or won't won't go into that again into much detail.

368
00:38:32,980 --> 00:38:37,750
But but they did the flyby of Pluto back in July of 2015,

369
00:38:37,750 --> 00:38:43,750
and also all those stunning images of Pluto that you saw that came as a result of that flyby.

370
00:38:43,750 --> 00:38:47,980
Pluto turned out to be a far more interesting Little Rock than we had thought

371
00:38:47,980 --> 00:38:54,250
has mountains that are made of water frozen as ice that is harder than stone.

372
00:38:54,250 --> 00:39:02,860
So a lot of really interesting features on that planet. And clearly, when you also when you see on planetary systems and moons, you know,

373
00:39:02,860 --> 00:39:07,300
these areas of smooth surface, you know, there's something interesting happening.

374
00:39:07,300 --> 00:39:14,710
There's some kind of tectonic activity or other activity which is able to sort of wipe out in a race things that would otherwise be looking like.

375
00:39:14,710 --> 00:39:21,460
For example, meteor rather impact crater sites that would be on these objects.

376
00:39:21,460 --> 00:39:29,170
OSIRIS-REx, we talked about as well the sample return mission. So this is a picture of the the spacecraft being assembled and the lift off.

377
00:39:29,170 --> 00:39:36,880
I actually got to go and see this launch. If you ever get a chance to go see a launch live, take it, break your date, whatever you have to do.

378
00:39:36,880 --> 00:39:42,460
Go, go see it. It's really quite an extraordinary thing to see a spacecraft take off into space.

379
00:39:42,460 --> 00:39:48,550
I like the fact, however, that OSIRIS-REx is perhaps the most tortured acronym that NACI has ever come up with.

380
00:39:48,550 --> 00:39:54,160
It stands for origins, spectral interpretation, resource identification, security,

381
00:39:54,160 --> 00:39:58,810
Regolith Explorer, and I will decipher that for you in a separate two hour lecture.

382
00:39:58,810 --> 00:40:05,050
Some other time, NASA also has something called the The Astrobiology Institute,

383
00:40:05,050 --> 00:40:10,660
which is a virtual institute where teams of researchers from different academic or research institutes

384
00:40:10,660 --> 00:40:16,840
come together to study astrobiology to help inform the design and development of technologies,

385
00:40:16,840 --> 00:40:21,340
tools and instruments to identify life on other planets and other places.

386
00:40:21,340 --> 00:40:23,860
And we run one of the teams.

387
00:40:23,860 --> 00:40:32,560
It's a 15 person team that has representatives from a wide variety of different universities in the U.S. and other science institutions.

388
00:40:32,560 --> 00:40:39,250
If the audio is working here, I have just a little clip from Natalie Cabral, who is the head of research at the City Institute.

389
00:40:39,250 --> 00:40:45,080
And also the head of our team for NASA. We'll see if this is going to work.

390
00:40:45,080 --> 00:40:54,060
Welcome, ladies, and welcome. My name is Natalie Cabral and the director of the council and Centre for Research at the City Institute.

391
00:40:54,060 --> 00:40:57,980
First, I would have to apologise because I will have to put these glasses on.

392
00:40:57,980 --> 00:41:02,120
The light is extremely bright today and really, this is needed.

393
00:41:02,120 --> 00:41:11,570
We are here today until it is located in the Chilean Altiplano, at an innovation for three hundred metres, so a little over fourteen thousand feet.

394
00:41:11,570 --> 00:41:13,790
And clearly there is a lot of wind today.

395
00:41:13,790 --> 00:41:20,630
The temperature is a little cooler than in buttonless, where we were at thirty five hundred metres and the environment is completely different.

396
00:41:20,630 --> 00:41:23,750
I am here with a very multidisciplinary teams.

397
00:41:23,750 --> 00:41:32,570
We have engineers, roboticists, we have microbiologists, geologists, environmental scientist, planetary geologist and astrobiologist.

398
00:41:32,570 --> 00:41:37,910
This project is under the umbrella of the Astrobiology Research Division at the City Institute,

399
00:41:37,910 --> 00:41:46,130
and it helps us better understand if life has a chance to appear on a different planet in the Solar System here today and for the next three days.

400
00:41:46,130 --> 00:41:51,290
We are here in an environment there where many hydrothermal springs on Mars.

401
00:41:51,290 --> 00:41:54,770
We have the mineral and spectral evidence of that.

402
00:41:54,770 --> 00:42:03,560
Many places like this one right now behind me, where energy, nutrients, water and shelter were present.

403
00:42:03,560 --> 00:42:05,330
So right now we are doing what we did.

404
00:42:05,330 --> 00:42:15,530
In fact, analysis trying to understand how the orbit imagery is informing us about what's happening at a microscopic scale.

405
00:42:15,530 --> 00:42:24,950
Our goal is really by understanding the special scale and spectral resolution and the new methods of approaching biosignature detection.

406
00:42:24,950 --> 00:42:32,390
What we want to do is to create the next generation of astrobiology exploration tools and technologies,

407
00:42:32,390 --> 00:42:36,170
since we know that Mars was habitable in the past.

408
00:42:36,170 --> 00:42:45,170
The next logical step is then to look for biosignatures traces of life on Mars, and obviously they are not clearly exposed at the surface.

409
00:42:45,170 --> 00:42:52,940
So we'll have to do a little forensic. But when I look at the landscape around me and those centres in the hydrothermal springs,

410
00:42:52,940 --> 00:43:01,490
I cannot help but think about our own planet and its beginning and primordial horrors that was pretty much looking like this.

411
00:43:01,490 --> 00:43:06,130
And it's an environment like that where life appeared on this planet.

412
00:43:06,130 --> 00:43:14,810
And now I would like to share with you this flag.

413
00:43:14,810 --> 00:43:18,530
This flag I take with me everywhere where I go.

414
00:43:18,530 --> 00:43:21,980
This is the said institute expedition flag number one.

415
00:43:21,980 --> 00:43:28,070
It was deployed last week still out there, but unless it is here today with a lot of wind, as you can see,

416
00:43:28,070 --> 00:43:41,180
flooding that still as close to forty three hundred metres over 14000 feet and the geyser is giving us a some sort of a fireworks to end this video.

417
00:43:41,180 --> 00:43:45,500
Flag number two is actually a few thousand kilometres south of here,

418
00:43:45,500 --> 00:43:51,230
with Dale Anderson in Antarctica and flight number three flew about a week before

419
00:43:51,230 --> 00:43:58,250
we left on the Sofia aeroplane with teachers and Formula Harmon and Bill Diamond.

420
00:43:58,250 --> 00:44:05,030
I thank you very much for sharing this time with us. And I say on behalf of my team, Thank you.

421
00:44:05,030 --> 00:44:10,040
I have a very nice evening where you are in New York and maybe see you soon at the City Institute.

422
00:44:10,040 --> 00:44:15,790
Goodbye. But in any case, hopefully that gives you an idea of some of the types of work that is done in the field.

423
00:44:15,790 --> 00:44:19,930
So in addition to being partners on on spacecraft missions,

424
00:44:19,930 --> 00:44:26,680
a lot of the work we do is basically field expeditions all over the planet, the Antarctic, the Arctic, et cetera.

425
00:44:26,680 --> 00:44:30,850
So she mentioned Dale Anderson, a Dale Anderson studies Limnology.

426
00:44:30,850 --> 00:44:35,020
Limnology is the study of of inland water ecosystems.

427
00:44:35,020 --> 00:44:40,150
So lakes and things like that. And he's in particular interested in frozen lakes.

428
00:44:40,150 --> 00:44:46,780
So he's been studying frozen lakes in the Antarctic and the dry valleys of the McMurdo Valley for decades now.

429
00:44:46,780 --> 00:44:52,990
And what he's interested in is biology and extreme by biological systems,

430
00:44:52,990 --> 00:44:57,970
complex biological systems that exist in these ecosystems or in these environments.

431
00:44:57,970 --> 00:45:05,620
The photograph below the text here is actually a photograph of cyanobacterial mounds that he finds under these frozen lakes.

432
00:45:05,620 --> 00:45:10,000
So they they go to these lakes, they clear off the snow on top of the ice.

433
00:45:10,000 --> 00:45:13,210
They drill through three metres of ice, typically to get to the water.

434
00:45:13,210 --> 00:45:18,070
They take heaters and they put them through the hole to melt them wide enough for a person to get through.

435
00:45:18,070 --> 00:45:21,910
And then they scuba dive under the ice, which sounds like a lot of fun to me.

436
00:45:21,910 --> 00:45:30,640
But in any case, they see these incredibly complex and interesting ecosystems where life thrives and exists

437
00:45:30,640 --> 00:45:36,370
in conditions that we would have thought some decades ago was not what was not possible.

438
00:45:36,370 --> 00:45:42,160
We also have people studying the neurology and chemistry Janice Bishop as a planetary scientist and chemist,

439
00:45:42,160 --> 00:45:50,980
and she does a lot of fieldwork on volcanic islands of hydrothermal sites, cold deserts and working also with actual Martian meteorite samples.

440
00:45:50,980 --> 00:45:52,540
There's a picture of her in Hawaii.

441
00:45:52,540 --> 00:46:01,420
He or she gets the tough duty of going to places like Maui, while Dale is in the Antarctic, and she's holding a handheld X-ray diffraction instrument.

442
00:46:01,420 --> 00:46:03,850
She's interested, in particular in clays.

443
00:46:03,850 --> 00:46:10,270
Clays, as are a mineral formation, are interesting because we know that clays only form in warm, wet conditions.

444
00:46:10,270 --> 00:46:17,950
So if you find clays on a place like Mars, which we have done, you can infer that Mars and one point in its past was warm and wet,

445
00:46:17,950 --> 00:46:23,290
which is now pretty well widely accepted in the scientific community that early on in its manifestation,

446
00:46:23,290 --> 00:46:28,120
Mars had a global ocean looked a lot like Earth. It was a blue planet, not a red planet.

447
00:46:28,120 --> 00:46:30,370
There's still a lot of water on Mars.

448
00:46:30,370 --> 00:46:36,670
There's enough water locked up in the ice on the poles that, if at all melted, it would cover the planet in about 20 metres of water.

449
00:46:36,670 --> 00:46:45,010
We see running water on Mars. We've had evidence of that from the orbiting reconnaissance satellite at Mars,

450
00:46:45,010 --> 00:46:52,750
and we've even discovered subterranean lakes or we believe we have, through radar data, discovered subterranean lakes on Mars.

451
00:46:52,750 --> 00:47:01,240
So there's water, there's geothermal heat. There are the conditions that perhaps a metre or more below the surface could still harbour life.

452
00:47:01,240 --> 00:47:07,660
NASA believes enough in this ad that they are launching what's called Mars 2020. Some of you may be familiar with that or even involved in it.

453
00:47:07,660 --> 00:47:11,500
The Mars 2020 mission is another Curiosity like rover.

454
00:47:11,500 --> 00:47:16,990
It looks very much like Curiosity. It has a lot more sophisticated instrumentation and technology on board,

455
00:47:16,990 --> 00:47:24,040
specifically designed to look for extant or extinct life on on the Red Planet.

456
00:47:24,040 --> 00:47:29,620
We also get involved in hardware and technology development. So this is Phillip Sarah Philip Sarrazin.

457
00:47:29,620 --> 00:47:35,140
He works in X-ray systems and design development of X-ray instrumentation.

458
00:47:35,140 --> 00:47:40,600
He and his colleague, David Blake at NASA Ames develop the so-called CheMin system,

459
00:47:40,600 --> 00:47:45,850
which is an X-ray diffraction chemical and minerals analysis instrument onboard the Curiosity rover.

460
00:47:45,850 --> 00:47:53,200
So while we are here speaking to one another, the Curiosity Rover CheMin system is up there on Mars,

461
00:47:53,200 --> 00:47:57,220
doing its thing and analysing the surface composition of the planet.

462
00:47:57,220 --> 00:48:05,590
A very interesting project, from my point of view is is Lawrence Doyle, who is a physicist and astronomer who is studying non-human communication.

463
00:48:05,590 --> 00:48:09,820
So he is for the first time. As far as we know, applying information theory,

464
00:48:09,820 --> 00:48:15,520
which was first developed for the telecommunications industry and applying that to non-human communication.

465
00:48:15,520 --> 00:48:23,560
The idea is to look for perhaps the underlying and fundamental mathematical constructs that constitute information being transmitted.

466
00:48:23,560 --> 00:48:28,270
So whether information or communications might be occurring in the electromagnetic

467
00:48:28,270 --> 00:48:35,320
spectrum or in through optics or through chemicals or acoustics or any other means.

468
00:48:35,320 --> 00:48:39,550
The important thing would be to find out if we pick up some sort of signal.

469
00:48:39,550 --> 00:48:45,130
Is that signal containing does that signal contain information or is it just some sort of random noise?

470
00:48:45,130 --> 00:48:53,350
As Lawrence likes to say, and I love this quote, it would be a shame to pick up a signal and not recognise the fact that it contains information.

471
00:48:53,350 --> 00:48:58,840
So he's got some really groundbreaking work funded by the Templeton Foundation in partnership

472
00:48:58,840 --> 00:49:06,070
with the Alaska Whale Foundation to study the communication patterns of humpback whales,

473
00:49:06,070 --> 00:49:11,050
which are extraordinary. They had a global communication network long before we did.

474
00:49:11,050 --> 00:49:14,170
And to to apply information theory to that,

475
00:49:14,170 --> 00:49:21,550
to understand the basic elements that constitute information and communications from the point of view of our city endeavours,

476
00:49:21,550 --> 00:49:31,030
the actual search for intelligent and technological civilisations, we take advantage of both the optical and the radio domain and the radio domain.

477
00:49:31,030 --> 00:49:33,160
The technology is is improving.

478
00:49:33,160 --> 00:49:46,660
That means more antenna, more dishes, a bigger, more sensitive receivers, broader frequency response, a broader dynamic range or bandwidth.

479
00:49:46,660 --> 00:49:52,330
The technology has the ability to look at at long range, but it's still limited in sensitivity.

480
00:49:52,330 --> 00:49:59,140
So sweaty endeavours could not, for example, pick up the kind of radiation that we emit from our planet, which is not directed.

481
00:49:59,140 --> 00:50:07,660
It's not high energy pointed in any particular way. We call it leakage. It's radio, broadcast, television, airport radar, et cetera.

482
00:50:07,660 --> 00:50:15,340
So if we were to discover an Earth like planet with similar kind of leakage, we wouldn't be able to detect it with today's technology.

483
00:50:15,340 --> 00:50:22,840
Of course, we expect that will will change in the future. And again, with our knowledge of exoplanets, we will be able to make more targeted searches.

484
00:50:22,840 --> 00:50:34,450
But nevertheless, it's it's it's still a compelling technology to deploy and to look for signs of technology as a proxy for intelligence.

485
00:50:34,450 --> 00:50:40,180
In terms of the comparison between radio and optical, it's got lower bandwidth, but more complex propagation.

486
00:50:40,180 --> 00:50:46,930
But I think it's also important to note that our search space at the moment is infinitesimally small,

487
00:50:46,930 --> 00:50:53,680
a good way to think about about how much of the sky we've looked at or how much of the universe we've studied.

488
00:50:53,680 --> 00:50:57,400
Next time you're at the beach, bring a measuring cup, stand at the shore,

489
00:50:57,400 --> 00:51:02,350
walk into the water, maybe go up into your knees and dip the measuring cup in the ocean.

490
00:51:02,350 --> 00:51:06,220
You probably won't find any whales, but you would, of course, be incorrect.

491
00:51:06,220 --> 00:51:12,920
Draw the conclusion that there are no whales in the ocean, but that's about the extent of the universe that we've explored through City and Deborah.

492
00:51:12,920 --> 00:51:17,710
So we're really not even at the tip of the iceberg when it comes to this.

493
00:51:17,710 --> 00:51:27,250
This search in the grand scheme of things, we are also now looking to use optical technology to search for laser pulses, for example.

494
00:51:27,250 --> 00:51:34,990
Lasers might be used for communications. They might be used for propulsion as the Breakthrough Starshot programme proposes to do.

495
00:51:34,990 --> 00:51:40,900
Lasers are quite visible and quite distinct from natural optical emissions.

496
00:51:40,900 --> 00:51:47,970
There tend to be monochromatic. They can be short pulse durations, so they're easy to spot right up the road from the City Institute,

497
00:51:47,970 --> 00:51:53,350
Mountain View is the Lawrence Livermore Laboratory, where the world's most powerful laser is based.

498
00:51:53,350 --> 00:51:57,430
And we know that, for example, if you took the output of that laser,

499
00:51:57,430 --> 00:52:03,160
you coupled it into one of the eight metre class telescopes we have on Earth and you shined it off into space.

500
00:52:03,160 --> 00:52:10,360
It would outshine the Sun by about ten thousand times. So lasers can be easily differentiated and detected from great distances.

501
00:52:10,360 --> 00:52:19,120
So another logical thing to potentially look for. So we're building a system of observatories where we'll put pairs of of four cameras,

502
00:52:19,120 --> 00:52:24,760
sets of four cameras or eight and total on six different locations around the planet three in the northern hemisphere

503
00:52:24,760 --> 00:52:32,830
or three in the southern hemisphere to survey all of the sky all of the time and just look for these optical pulses.

504
00:52:32,830 --> 00:52:40,180
And that's what we call the Laser City Project. In terms of traditional radio city, we have a lot of activity going on.

505
00:52:40,180 --> 00:52:45,250
Our plan over the next few years is to continue to develop World-Class techno signature

506
00:52:45,250 --> 00:52:50,380
and city capability search capabilities and to conduct World-Class searches.

507
00:52:50,380 --> 00:52:57,760
We have a radio telescope array called the Allen Telescope Array in Northern California, partially funded by Paul Allen from Microsoft.

508
00:52:57,760 --> 00:53:06,400
And we are in the process at the moment of upgrading all of the feeds or the antenna on those dishes to give us more frequency

509
00:53:06,400 --> 00:53:15,760
response out to 15 gigahertz improved sensitivity so we can look further out into space and improve overall system performance.

510
00:53:15,760 --> 00:53:21,490
So we'll be be upgrading all of the dishes over the next couple of years to this second generation technology.

511
00:53:21,490 --> 00:53:25,720
We're also working now in a really interesting programme with the VLA,

512
00:53:25,720 --> 00:53:31,330
which is the very large array operated by the National Radio Astronomy Organisation in the United States

513
00:53:31,330 --> 00:53:37,030
and the VHLAH is the most advanced and sensitive array telescope in the northern hemisphere at this point.

514
00:53:37,030 --> 00:53:41,590
And it's not typically used. It's not ever used for city endeavours.

515
00:53:41,590 --> 00:53:49,750
Although interestingly, if you get a copy of the film, contact the dishes on the cover of that movie poster art the Velar.

516
00:53:49,750 --> 00:53:58,840
But we have reached an agreement with the National Radio Astronomy Observatory to put out 100

517
00:53:58,840 --> 00:54:05,650
gigabit ethernet spigot on the back ends of the VLA and basically siphon off data in real time,

518
00:54:05,650 --> 00:54:09,250
commensal or, in other words, simultaneously with whatever else they're looking at.

519
00:54:09,250 --> 00:54:15,810
And so this is going to give us an update. I think for some extraordinary discoveries that you know, may not just be set,

520
00:54:15,810 --> 00:54:20,670
it here may not be steady at all, but even just some phenomenal radio astronomy could come from that.

521
00:54:20,670 --> 00:54:27,540
So very exciting project. We're also partnering with Caltech to put some different back Intel technology on the

522
00:54:27,540 --> 00:54:34,200
Allen Telescope Array to undertake a wide field survey for FRBs or fast radio bursts.

523
00:54:34,200 --> 00:54:41,700
If you're anything to do with the astronomy community, you know the astronomy community is very excited by these phenomena, which we don't understand.

524
00:54:41,700 --> 00:54:48,450
They're extremely high energy radio bursts from very, very far away in a millisecond pulse of radio burst energy.

525
00:54:48,450 --> 00:54:53,700
These objects have put forth more energy than our Sun does in an entire year.

526
00:54:53,700 --> 00:55:00,030
So a fascinating area of research that we will continue to investigate with our own Allen Telescope array.

527
00:55:00,030 --> 00:55:04,980
There's also interesting questions about indirect observations of technosignatures.

528
00:55:04,980 --> 00:55:10,080
For example, might transit life curve anomalies suggest alien technology?

529
00:55:10,080 --> 00:55:15,420
So ever anybody heard of the Tabby's Star that made the news a few years ago out of the Kepler data?

530
00:55:15,420 --> 00:55:22,800
So this was a star whose light curve, instead of just dipping a slight amount suggesting a planet dipped by 20 percent,

531
00:55:22,800 --> 00:55:29,280
something huge and interesting is going on in this planet. One of the speculations was maybe this is an alien megastructure.

532
00:55:29,280 --> 00:55:35,430
Maybe it's a Dyson sphere or some other kind of of of a technological object or artefact.

533
00:55:35,430 --> 00:55:40,230
I would say that the current theories that I believe are probably the most plausible is that this is dust,

534
00:55:40,230 --> 00:55:44,730
but we don't have any definitive results yet on exactly what is going on.

535
00:55:44,730 --> 00:55:47,520
It remains an interesting mystery, but it does it again.

536
00:55:47,520 --> 00:55:56,640
Just suggest the broader possibility that there are other indirect phenomena we may observe that may in fact be signatures of technology.

537
00:55:56,640 --> 00:55:59,370
Can we detect biosignatures in exoplanet atmospheres?

538
00:55:59,370 --> 00:56:06,780
So when the James Webb telescope launches, we're going to have the ability to probe exoplanet atmospheres and understand their composition.

539
00:56:06,780 --> 00:56:13,440
And it is possible, for example, to look at an atmospheric composition and make a determination that that

540
00:56:13,440 --> 00:56:17,790
composition couldn't exist without the existence of biology or life as we know it,

541
00:56:17,790 --> 00:56:24,510
or it couldn't be stable. So we might be able to infer the presence of biology just by studying exoplanet atmospheres,

542
00:56:24,510 --> 00:56:32,490
we might be able to reveal technology in the survey of of exoplanet atmospheres.

543
00:56:32,490 --> 00:56:35,730
If we look for something interesting, like SF six, for example,

544
00:56:35,730 --> 00:56:40,710
we might discover something that nature actually doesn't produce, but only technology produces.

545
00:56:40,710 --> 00:56:47,280
And that would, of course, at least be another proxy for the presence of technology or intelligence on that planet.

546
00:56:47,280 --> 00:56:55,530
Is it possible to detect something like terraforming? You've heard of the TRAPPIST system, which is a planetary system of seven stars and planets,

547
00:56:55,530 --> 00:56:59,730
rather all of which are about Earth sized planets around an M dwarf star.

548
00:56:59,730 --> 00:57:05,700
Three of those planets are known to be in the so-called habitable zone of that dwarf.

549
00:57:05,700 --> 00:57:14,010
If we were to start looking at the atmospheres of those exoplanets and we found a couple or three with, say, identical atmospheres.

550
00:57:14,010 --> 00:57:16,590
That's probably not something that nature does or would do,

551
00:57:16,590 --> 00:57:22,290
and we might infer from that that somebody's been doing some terraforming and or messing around with those planetary environments.

552
00:57:22,290 --> 00:57:30,570
So lots of interesting ideas and thoughts about indirect observations of phenomena that we might ascribe to technological civilisations.

553
00:57:30,570 --> 00:57:37,350
Just briefly about education and outreach programmes. Again, because I I mentioned how I believe they are, they are so important.

554
00:57:37,350 --> 00:57:45,620
These are eight interesting images that I will ask you for a moment to ponder about what it is they have in common.

555
00:57:45,620 --> 00:57:47,090
And I can see the dynamics there,

556
00:57:47,090 --> 00:57:52,700
thinking about the maths and trying to figure out the orbital dynamics or something else going on, that's common between those.

557
00:57:52,700 --> 00:57:56,210
Well, the answer that I'm looking for has nothing to do with science.

558
00:57:56,210 --> 00:58:02,750
It has to do with the fact that every one of the objects you see was on the front page of the New York Times at one point.

559
00:58:02,750 --> 00:58:08,540
So that's really interesting. There aren't many other branches of science that have the ability so often to make

560
00:58:08,540 --> 00:58:12,620
the front page of the New York Times as space science and space exploration.

561
00:58:12,620 --> 00:58:17,090
And that, I think, gives those of us doing this kind of work a tremendous opportunity,

562
00:58:17,090 --> 00:58:24,020
a tremendous platform for public engagement, for education and outreach, about our science and about science more broadly.

563
00:58:24,020 --> 00:58:27,380
And as you can see sort of from the breadth of research we do at the institute,

564
00:58:27,380 --> 00:58:32,870
there isn't a branch of science that doesn't touch space exploration and steady endeavours.

565
00:58:32,870 --> 00:58:37,730
And so you can use a platform like space exploration to teach all science.

566
00:58:37,730 --> 00:58:41,000
And there are two things that all children love.

567
00:58:41,000 --> 00:58:45,690
Anybody know what they are. Dinosaurs and space.

568
00:58:45,690 --> 00:58:53,430
So the you know, the first group that comes together and makes the blockbuster movie about dinosaurs in space is really going to have a home run.

569
00:58:53,430 --> 00:59:01,290
But in any case, so why not take advantage of things that children find and young people find and humans find inherently

570
00:59:01,290 --> 00:59:08,490
fascinating and use that and leverage that interest to teach science to to help improve science literacy?

571
00:59:08,490 --> 00:59:15,060
We have a huge problem of science literacy in our own country. There could even be problems in certain parts of the leadership in our country.

572
00:59:15,060 --> 00:59:19,650
In that regard, I won't go into details, but it's it's science.

573
00:59:19,650 --> 00:59:26,400
Literacy is extremely important. Having a scientifically literate electorate is extremely important for our future.

574
00:59:26,400 --> 00:59:33,960
So it's it's really important and interesting and so that we believe is an opportunity and a responsibility for us to do this.

575
00:59:33,960 --> 00:59:39,420
Public engagement and outreach. We're very active in terms of telling stories around the work we do.

576
00:59:39,420 --> 00:59:44,670
So when something interesting happens, we try to get it out in the news. So we publish news releases.

577
00:59:44,670 --> 00:59:54,450
We had an interesting one, for example, in mid-March where we were using a drone to map icy lava tubes in Iceland as a precursor for developing those

578
00:59:54,450 --> 01:00:01,230
technologies that will be used on the Moon and on Mars to go into the lava tubes that exist on both of those objects.

579
01:00:01,230 --> 01:00:06,720
And interestingly, we've been going to a place called Devon Island, which is in the high Canadian Arctic.

580
01:00:06,720 --> 01:00:10,500
It's the largest uninhabited island on Earth. It looks like Mars.

581
01:00:10,500 --> 01:00:17,160
If the sky were kind of pinkish, you'd say, OK, I'm on Mars. It's red, it's cold, it's dry.

582
01:00:17,160 --> 01:00:22,110
NASA and the Mars Institute in the City Institute have been collaborating there for 20 years,

583
01:00:22,110 --> 01:00:25,110
doing things like developing the technologies for rovers,

584
01:00:25,110 --> 01:00:32,940
for habitats, for spacesuits, even for human behaviour in these kind of conditions, exploration conditions, et cetera.

585
01:00:32,940 --> 01:00:35,520
Last year, we took Google along with us.

586
01:00:35,520 --> 01:00:43,350
And what Google did there was bring a team to use Google cameras and technologies to take pictures and do mappings and so forth.

587
01:00:43,350 --> 01:00:49,440
The cool thing is right now Devon Island is on Street View, so.

588
01:00:49,440 --> 01:00:56,310
So check it out. So go to Google and go to Street View and you can walk the non-existing streets of Devon Island.

589
01:00:56,310 --> 01:01:03,210
But you get a sense of what this absolutely extraordinary and very otherworldly place right on our own planet looks like.

590
01:01:03,210 --> 01:01:09,570
Lots of fun. Other vehicles for outreach. We have a radio show and podcast podcast called Big Picture Science.

591
01:01:09,570 --> 01:01:13,170
It's a weekly programme. It's not restricted to space science and exploration.

592
01:01:13,170 --> 01:01:21,660
It covers all science. It should come with an FCC warning that says if you don't like puns, don't watch the programme but or listen to it.

593
01:01:21,660 --> 01:01:29,490
But it's really it's quite brilliant. They do an amazing job, and you can listen to past and present episodes from their website.

594
01:01:29,490 --> 01:01:34,530
The Big Picture Science or our own City Dawg, but it's it's a wonderful public engagement tool.

595
01:01:34,530 --> 01:01:43,230
We have monthly lecture series called said. He talks that we deliver at an auditorium operated by at SwRI, just down the road from us.

596
01:01:43,230 --> 01:01:47,430
And these are free and open to the public. And we videotaped them.

597
01:01:47,430 --> 01:01:56,370
We livestream them when we can, and we give scientists from our own institute, from NASA, from around the world.

598
01:01:56,370 --> 01:02:03,990
Opportunity come and speak and talk about their work. And there's a library of over 400 lectures on our YouTube channel, called said.

599
01:02:03,990 --> 01:02:12,570
He talks that you can explore it, covering everything from dark energy and dark matter to matter to advanced propulsion technologies and so forth.

600
01:02:12,570 --> 01:02:15,810
We have an artist in residence programme where artists spend time with our

601
01:02:15,810 --> 01:02:20,970
scientists over a summer period and get inspired for new works of creativity.

602
01:02:20,970 --> 01:02:26,310
And it's a new method of of of kind of understanding and perceiving the science we do.

603
01:02:26,310 --> 01:02:32,700
Some of our scientists get an opportunity to look at their work interpreted by an artist and see something that they never realised was there before.

604
01:02:32,700 --> 01:02:35,610
So it's quite good. We're very active on Twitter and Facebook.

605
01:02:35,610 --> 01:02:41,160
We do weekly Facebook Live presentations where we put one of our scientists or colleagues from other

606
01:02:41,160 --> 01:02:46,440
organisations and institutions in front of the camera and talk to them about their science and their work.

607
01:02:46,440 --> 01:02:50,620
And we let the public watch and ask questions and answer those questions in real time.

608
01:02:50,620 --> 01:02:56,610
So it's good fun. I like to think again, I mentioned this at the very beginning.

609
01:02:56,610 --> 01:03:01,110
One of the so-called one of the powers of the institute or one of the powers that I think we're trying to exploit,

610
01:03:01,110 --> 01:03:03,750
and that's the power of partnerships and collaboration.

611
01:03:03,750 --> 01:03:09,660
These are some of the organisations that we're collaborating with in terms of both funding and partnerships and programmes

612
01:03:09,660 --> 01:03:16,650
like the Frontier Development Lab and and in academic relationships very quickly about the Frontier Development Lab.

613
01:03:16,650 --> 01:03:21,420
So this was a programme conceived of by the Office of the Chief Technologist at NASA headquarters,

614
01:03:21,420 --> 01:03:26,280
and it was really designed to look at and explore three fundamental ideas.

615
01:03:26,280 --> 01:03:31,620
One, the applicability of artificial intelligence and machine learning to basic science

616
01:03:31,620 --> 01:03:37,380
priorities to the efficacy of interdisciplinary teams working on short time horizons.

617
01:03:37,380 --> 01:03:42,720
Three The ability of public private partnership to accelerate NASA's objectives. A better, faster cheaper.

618
01:03:42,720 --> 01:03:49,590
Results in science. It's basically a programme where we bring together early career PhDs and machine learning and artificial intelligence.

619
01:03:49,590 --> 01:03:52,560
We pair them off with their counterparts in science domains,

620
01:03:52,560 --> 01:03:58,710
and they take on projects that are science based of interest to to NASA and other partners.

621
01:03:58,710 --> 01:04:02,460
This initial partnership is from the City Institute and NASA.

622
01:04:02,460 --> 01:04:09,030
This year we have Google Cloud as our premier sponsor partner, providing technology, money,

623
01:04:09,030 --> 01:04:14,700
subject matter experts, cloud compute resources, et cetera that we could otherwise not afford.

624
01:04:14,700 --> 01:04:20,250
And we have, as of last year, a partnership with Oxford University and the European Space Agency,

625
01:04:20,250 --> 01:04:26,760
bringing the FDL programme to Europe to teams that I described earlier were based here at Oxford.

626
01:04:26,760 --> 01:04:32,190
And this year again, we will be having three teams at Oxford University.

627
01:04:32,190 --> 01:04:42,420
Seven teams at the City Institute in the United States. And it's it's evolving into a wonderful example that not only, I think,

628
01:04:42,420 --> 01:04:46,200
proves out the three theses that Nasser was trying to exercise in the first place.

629
01:04:46,200 --> 01:04:54,960
But what interdisciplinary science can achieve? What these teams achieve in an eight week intense workshop is absolutely extraordinary.

630
01:04:54,960 --> 01:05:02,670
Simon Jackman from Oxford here can tell you a lot more about what the the two ESA teams did last year and what they're going to be doing this year.

631
01:05:02,670 --> 01:05:05,730
And if you want to find out more about how you might get involved,

632
01:05:05,730 --> 01:05:11,460
please speak to Simon if you'd like to get more information to get involved in the programmes run in the U.S., you can.

633
01:05:11,460 --> 01:05:18,690
You can speak to me or reach out to me, but it's it's really an interesting and compelling programme, an opportunity.

634
01:05:18,690 --> 01:05:21,300
And we'd love to see it grow and prosper.

635
01:05:21,300 --> 01:05:28,830
I think there's a lot more compelling and amazing work that's going to be done off of this programme in the years ahead.

636
01:05:28,830 --> 01:05:31,320
These are some of the other organisations that are involved.

637
01:05:31,320 --> 01:05:38,160
Companies like Intel and Videla, they're bringing hardware, you know, massive compute resources to bear on the programme.

638
01:05:38,160 --> 01:05:44,740
They're bringing funding IBM, Lockheed Martin, the X-Prize, et cetera.

639
01:05:44,740 --> 01:05:48,870
So this is really what collaboration and partnership is all about.

640
01:05:48,870 --> 01:05:53,790
And an amazing science is, is the result or the output.

641
01:05:53,790 --> 01:06:00,690
Just as a quick example, last year, in twenty 2018, we had seven teams in the US for this eight week workshop.

642
01:06:00,690 --> 01:06:08,010
We had two teams working on astrobiology questions to teams on space weather, to teams on space resources.

643
01:06:08,010 --> 01:06:14,850
And one team studying exoplanets and developing new algorithms for planet data extraction on the TESS mission.

644
01:06:14,850 --> 01:06:18,430
And again, we we've been expanding the partnerships year over year.

645
01:06:18,430 --> 01:06:21,720
We're about to start on our fourth year of the programme.

646
01:06:21,720 --> 01:06:27,510
And what was achieved, for example, last year, we had nine teams, including the two here at Oxford.

647
01:06:27,510 --> 01:06:31,620
They were from studying six domains. We had 12 partner organisations.

648
01:06:31,620 --> 01:06:35,640
Thirty six, sorry. Thirty seven researchers. Forty two mentors.

649
01:06:35,640 --> 01:06:40,470
Fifteen countries were represented. They came from 25 different universities.

650
01:06:40,470 --> 01:06:46,530
We had thirty two speakers interacting with the students and I rather the participants in the programme.

651
01:06:46,530 --> 01:06:52,080
We have a relatively modest support staff of 10 people supporting that programme.

652
01:06:52,080 --> 01:07:00,030
Again, it runs for eight weeks. It starts with a one week bootcamp that both in the UK operation in the US.

653
01:07:00,030 --> 01:07:08,670
It ends with a grand finale last year hosted an intel. This year will be hosted at Google and we we developed a two hundred and sixteen page report.

654
01:07:08,670 --> 01:07:10,650
I assume you can probably just hold it up for everybody,

655
01:07:10,650 --> 01:07:17,340
but it's available on the Frontier Development Board website if you'd like to see the output of the teams and the science that was done.

656
01:07:17,340 --> 01:07:21,870
What's also extraordinary is in this eight week workshop period, a peer reviewed journal.

657
01:07:21,870 --> 01:07:28,320
Articles have been generated by many of the teams, which in an eight week research undertaking, is somewhat extraordinary.

658
01:07:28,320 --> 01:07:37,530
So that's the the programme, I think is an extraordinary opportunity for all of us in terms of research and education and outreach.

659
01:07:37,530 --> 01:07:45,330
And again, I'd like to think that we can build on this model of partnership and cross collaboration and interdisciplinary science,

660
01:07:45,330 --> 01:07:49,800
bringing disparate disciplines together to do extraordinary things.

661
01:07:49,800 --> 01:07:58,330
And with that, I thank you. How?

662
01:07:58,330 --> 01:08:23,760
One last, one last thing. This is just a little bit of 60 second fun.

663
01:08:23,760 --> 01:08:30,120
Finding life beyond Earth is no longer a dream.

664
01:08:30,120 --> 01:08:39,330
It's a discovery that will likely be made during our lifetimes and it will change everything.

665
01:08:39,330 --> 01:08:46,670
We have been here for more than 30 years, at the forefront of a quest that many consider science fiction.

666
01:08:46,670 --> 01:08:51,740
Mars is the closest planet where we might find the possibilities of alien life.

667
01:08:51,740 --> 01:08:56,690
We are home to over nine explorers scientists. This just takes your breath away.

668
01:08:56,690 --> 01:09:00,530
Working towards a singular purpose kind of best to understand what you have in

669
01:09:00,530 --> 01:09:05,040
your own backyard as you're looking up into the cosmos to understand the origin,

670
01:09:05,040 --> 01:09:13,280
prevalence and nature of life in the universe. What we are doing is to try to understand Are we alone in the Solar System?

671
01:09:13,280 --> 01:09:19,760
Why do we pursue our mission? Because the discovery of life beyond Earth will change everything we understand

672
01:09:19,760 --> 01:09:28,180
about the human past and will open a new window into our collective future.

673
01:09:28,180 --> 01:09:57,494
We are trying to understand why we even exist. We are the City Institute.
