00:00:35,489 astrobiologist a show where we celebrate 5 00:00:39,619 --> 00:00:38,280 science and celebrate scientists my name 6 00:00:41,240 --> 00:00:39,629 is Sanjay Amin this program is made 7 00:00:43,580 --> 00:00:41,250 possible by contributions from the NASA 8 00:00:46,850 --> 00:00:43,590 Astrobiology program and the non profit 9 00:00:49,100 --> 00:00:46,860 blue marble space last month all of us 10 00:00:50,959 --> 00:00:49,110 astrobiologists were at the astrobiology 11 00:00:51,500 --> 00:00:50,969 Science Conference in Bellevue 12 00:00:53,290 --> 00:00:51,510 Washington 13 00:00:55,310 --> 00:00:53,300 across the lake from Seattle in the 14 00:00:57,130 --> 00:00:55,320 northwest corner of the United States 15 00:00:59,270 --> 00:00:57,140 where we had a week of intense 16 00:01:01,760 --> 00:00:59,280 multidisciplinarity and to celebrate 17 00:01:02,869 --> 00:01:01,770 this multidisciplinarity who else then 18 00:01:05,000 --> 00:01:02,879 to invite to the show then 19 00:01:07,880 --> 00:01:05,010 astrobiologists extraordinaire dr. 20 00:01:10,120 --> 00:01:07,890 lucien waka wits with who is an 21 00:01:13,280 --> 00:01:10,130 astronomer at the Adler Planetarium in 22 00:01:15,560 --> 00:01:13,290 Chicago as well as the fifth bearish 23 00:01:17,149 --> 00:01:15,570 bloomberg chair of astrobiology at the 24 00:01:18,499 --> 00:01:17,159 Library of Congress and we're really 25 00:01:19,999 --> 00:01:18,509 excited by this show we're going to talk 26 00:01:22,550 --> 00:01:20,009 about a lot of different exciting things 27 00:01:25,550 --> 00:01:22,560 but first it's time for your favorite 28 00:01:27,620 --> 00:01:25,560 background quiz last month Mike if you 29 00:01:30,560 --> 00:01:27,630 could put up our background from last 30 00:01:34,190 --> 00:01:30,570 month several of you got it right it is 31 00:01:36,289 --> 00:01:34,200 of course fly geyser in Nevada purchased 32 00:01:39,350 --> 00:01:36,299 recently by the Burning Man foundation 33 00:01:40,789 --> 00:01:39,360 and it is a geyser that's very rich in 34 00:01:43,460 --> 00:01:40,799 silica the water coming out is around 35 00:01:45,590 --> 00:01:43,470 200 degrees Fahrenheit roughly thirty 93 36 00:01:48,499 --> 00:01:45,600 degrees Celsius and the geyser you see 37 00:01:50,480 --> 00:01:48,509 is about about let's see five feet tall 38 00:01:52,429 --> 00:01:50,490 one and a half meters so that's it's 39 00:01:54,469 --> 00:01:52,439 really really beautiful sight and I was 40 00:01:57,380 --> 00:01:54,479 a background from last month and several

00:03:23,249 --> 00:03:19,930 oh my pleasure thanks for having me on 79 00:03:24,839 --> 00:03:23,259 the show so you do so many things I we 80 00:03:25,979 --> 00:03:24,849 have going to be speaking about half an 81 00:03:27,240 --> 00:03:25,989 hour and then we'll open it up to the 82 00:03:29,039 --> 00:03:27,250 questions because I'm sure we're gonna 83 00:03:30,869 --> 00:03:29,049 fill it up with with all the questions 84 00:03:32,069 --> 00:03:30,879 from our audience um but to begin with 85 00:03:34,319 --> 00:03:32,079 could you tell us a little bit about 86 00:03:36,149 --> 00:03:34,329 your path as a you're now an astronomer 87 00:03:37,679 --> 00:03:36,159 and astrobiologist wasn't it was this a 88 00:03:39,449 --> 00:03:37,689 linear path through school and then 89 00:03:41,099 --> 00:03:39,459 later on as a postdoc and later on so 90 00:03:44,520 --> 00:03:41,109 tell us a little bit about your s-curve 91 00:03:48,360 --> 00:03:44,530 perhaps as a career sure yeah I you know 92 00:03:50,460 --> 00:03:48,370 I started wanting a career in astronomy 93 00:03:53,819 --> 00:03:50,470 when I was actually in high school and 94 00:03:55,559 --> 00:03:53,829 it was really because you know I we 95 00:03:57,360 --> 00:03:55,569 talked a little bit before the show like 96 00:03:59,699 --> 00:03:57,370 yeah many of our colleagues have these 97 00:04:01,559 --> 00:03:59,709 stories about like how they star games 98 00:04:03,479 --> 00:04:01,569 as a child or all of those sort of 99 00:04:05,670 --> 00:04:03,489 things like I am from New York City I 100 00:04:08,429 --> 00:04:05,680 have never owned a telescope personally 101 00:04:10,140 --> 00:04:08,439 although I've used many telescopes and 102 00:04:12,689 --> 00:04:10,150 so you know my interest in astronomy 103 00:04:15,050 --> 00:04:12,699 really came from being interested in 104 00:04:17,670 --> 00:04:15,060 physics and chemistry and wanting to 105 00:04:22,110 --> 00:04:17,680 find a way to combine all the sciences 106 00:04:23,689 --> 00:04:22,120 and so I think astrobiology despite 107 00:04:26,279 --> 00:04:23,699 having astronomy and biology 108 00:04:27,270 --> 00:04:26,289 specifically in its name is like the 109 00:04:30,720 --> 00:04:27,280 ultimate intern 110 00:04:33,300 --> 00:04:30,730 disciplinary science in many ways so you 111 00:04:35,310 --> 00:04:33,310 know I started out life as a physics 112 00:04:37,980 --> 00:04:35,320 major and went on to grad school in 113 00:04:40,710 --> 00:04:37,990 astronomy with the intention of studying 114 00:04:42,570 --> 00:04:40,720 magnetic activity and stars so I was 115 00:04:45,540 --> 00:04:42,580 very much just a straight-up astronomer 116 00:04:47,400 --> 00:04:45,550 for a long time and it was actually an 117 00:04:47,970 --> 00:04:47,410 astrobiologist at University of 118 00:04:50,760 --> 00:04:47,980 Washington 119 00:04:52,770 --> 00:04:50,770 what do you Sullivan who kind of pulled 120 00:04:54,360 --> 00:04:52,780 me aside like midway through my grad 121 00:04:57,060 --> 00:04:54,370 career like maybe three years into grad 122 00:04:58,890 --> 00:04:57,070 school and was like hey the SETI 123 00:05:01,590 --> 00:04:58,900 Institute is having this like 124 00:05:03,240 --> 00:05:01,600 invitation-only workshop where they're 125 00:05:06,390 --> 00:05:03,250 gonna talk about whether the stars you 126 00:05:08,550 --> 00:05:06,400 study these little red stars are good or 127 00:05:10,860 --> 00:05:08,560 bad hosts for potentially habitable 128 00:05:12,780 --> 00:05:10,870 planets and it was like you should go to 129 00:05:15,990 --> 00:05:12,790 that and I was like yeah I should go to 130 00:05:18,780 --> 00:05:16,000 that so that was kind of like my first 131 00:05:20,760 --> 00:05:18,790 introduction into astrobiology and and 132 00:05:22,560 --> 00:05:20,770 from there I was like totally hooked 133 00:05:24,630 --> 00:05:22,570 because of course who doesn't want to 134 00:05:28,230 --> 00:05:24,640 know more about life in the universe and 135 00:05:31,140 --> 00:05:28,240 where we might find it so yeah after 136 00:05:33,659 --> 00:05:31,150 grad school I did postdoc 137 00:05:35,880 --> 00:05:33,669 first at Berkeley for three years which 138 00:05:38,640 --> 00:05:35,890 was a really exciting time because I 139 00:05:40,800 --> 00:05:38,650 joined the Kepler team just before the 140 00:05:43,740 --> 00:05:40,810 Kepler mission launched and got to be 141 00:05:47,250 --> 00:05:43,750 part of that mission from day day zero 142 00:05:49,260 --> 00:05:47,260 and then after that went on to postdoc 143 00:05:50,640 --> 00:05:49,270 at Princeton where I continued a lot of 144 00:05:51,960 --> 00:05:50,650 the work that I was doing with Kepler 145 00:05:53,430 --> 00:05:51,970 and also broadened it to some of the 146 00:05:55,980 --> 00:05:53,440 stuff that we'll talk about today and 147 00:05:59,420 --> 00:05:55,990 I've been at the Adler the planetarium 148 00:06:01,650 --> 00:05:59,430 at the planetarium in Chicago since 2014 149 00:06:03,630 --> 00:06:01,660 very cool very cool yeah I've been to 150 00:06:05,940 --> 00:06:03,640 the Adler Planetarium once and it's just 151 00:06:07,440 --> 00:06:05,950 a very mesmerizing place great exhibits 152 00:06:09,719 --> 00:06:07,450 and really interesting people to talk to 153 00:06:11,070 --> 00:06:09,729 there so if any of you are watching go 154 00:06:15,390 --> 00:06:11,080 do check out the Adler Planetarium in 155 00:06:17,490 --> 00:06:15,400 Chicago it's amazing and so you're those 156 00:06:18,960 --> 00:06:17,500 little red stars that I thought we can 157 00:06:21,000 --> 00:06:18,970 talk about it a little bit are our own 158 00:06:22,440 --> 00:06:21,010 Sun is the G star I'm but those little 159 00:06:25,440 --> 00:06:22,450 red star those M dwarfs are actually 160 00:06:26,940 --> 00:06:25,450 much more common in in a galaxy than the 161 00:06:28,800 --> 00:06:26,950 G stars can you tell us a little bit 162 00:06:31,440 --> 00:06:28,810 about the potential habitability of 163 00:06:35,250 --> 00:06:31,450 these of these of planets around those 164 00:06:38,760 --> 00:06:35,260 small M dwarf stars sure yeah so these 165 00:06:41,020 --> 00:06:38,770 little red stars M dwarfs make up about 166 00:06:45,190 --> 00:06:41,030 70 to 75% of all 167 00:06:48,070 --> 00:06:45,200 the stars in our galaxy and they're very 168 00:06:50,020 --> 00:06:48,080 faint compared to our sons so they you 169 00:06:54,100 --> 00:06:50,030 know they're not made of very much fuel 170 00:06:56,860 --> 00:06:54,110 to begin with but they're also very very 171 00:07:00,100 --> 00:06:56,870 thrifty with their fuels so they burn 172 00:07:02,980 --> 00:07:00,110 very low luminosity over a very long 173 00:07:04,450 --> 00:07:02,990 period of time and actually they're so 174 00:07:06,160 --> 00:07:04,460 faint that even if you were in the 175 00:07:08,760 --> 00:07:06,170 darkest place on earth you would never 176 00:07:12,130 --> 00:07:08,770 be able to see one with your naked eye 177 00:07:14,920 --> 00:07:12,140 but the stars above you are just like a 178 00:07:16,120 --> 00:07:14,930 tiny fraction of what there's and there 179 00:07:19,390 --> 00:07:16,130 is out there and most of them are these 180 00:07:21,400 --> 00:07:19,400 little Reds worse so the the reason that 181 00:07:23,350 --> 00:07:21,410 even though they're so plentiful they 182 00:07:25,630 --> 00:07:23,360 had been discounted for many years by 183 00:07:28,420 --> 00:07:25,640 astrobiologists as potential hosts for 184 00:07:30,370 --> 00:07:28,430 habitable planets is that they don't 185 00:07:32,560 --> 00:07:30,380 give off very much light and that means 186 00:07:34,510 --> 00:07:32,570 that planets that are around them in 187 00:07:36,820 --> 00:07:34,520 order to get that same kind of work that 188 00:07:39,820 --> 00:07:36,830 we get from our Sun have to be cuddled 189 00:07:41,800 --> 00:07:39,830 in pretty close to the start so that 190 00:07:43,870 --> 00:07:41,810 would be fine if it wasn't for the fact 191 00:07:46,510 --> 00:07:43,880 that they also have what we call 192 00:07:49,270 --> 00:07:46,520 magnetic activity so in the same way 193 00:07:51,460 --> 00:07:49,280 that our Sun has solar flares these big 194 00:07:54,730 --> 00:07:51,470 bursts of high-energy radiation and 195 00:07:56,380 --> 00:07:54,740 ultraviolet and x-rays that come off of 196 00:07:58,990 --> 00:07:56,390 our star and you know influence our 197 00:08:01,390 --> 00:07:59,000 planet along with you know actual like 198 00:08:03,670 --> 00:08:01,400 particles from the Sun that stream into 199 00:08:05,680 --> 00:08:03,680 our planet create you know occasionally 200 00:08:07,780 --> 00:08:05,690 like disturbances in our technology or 201 00:08:12,670 --> 00:08:07,790 just beautiful you know northern and 202 00:08:15,400 --> 00:08:12,680 southern lights the stars M dwarfs that 203 00:08:16,720 --> 00:08:15,410 would be hosting these planets they'd 204 00:08:19,060 --> 00:08:16,730 have to be super close to them but then 205 00:08:21,000 --> 00:08:19,070 they also have these huge flares and 206 00:08:23,230 --> 00:08:21,010 that makes the planets very vulnerable 207 00:08:26,170 --> 00:08:23,240 to the effects of this high-energy 208 00:08:29,410 --> 00:08:26,180 radiation so for a long time people just 209 00:08:31,990 --> 00:08:29,420 assumed like oh well if you're a planet 210 00:08:33,100 --> 00:08:32,000 that that that close to the star you 211 00:08:35,380 --> 00:08:33,110 know you're gonna be completely 212 00:08:37,090 --> 00:08:35,390 irradiated and like anything on the 213 00:08:40,360 --> 00:08:37,100 surface would be just you know like 214 00:08:42,040 --> 00:08:40,370 wiped out immediately that radiation and 215 00:08:44,710 --> 00:08:42,050 the particles that come off the star can 216 00:08:46,210 --> 00:08:44,720 also erode the planetary atmosphere as 217 00:08:49,140 --> 00:08:46,220 well so it could even scrape the 218 00:08:51,220 --> 00:08:49,150 atmosphere off a planet completely 219 00:08:53,560 --> 00:08:51,230 because of the gravitational interaction 220 00:08:54,370 --> 00:08:53,570 between the planet and the star people 221 00:08:56,710 --> 00:08:54,380 were also were 222 00:08:58,690 --> 00:08:56,720 read that the the planet could be locked 223 00:09:00,520 --> 00:08:58,700 to the star so you only had one day side 224 00:09:02,110 --> 00:09:00,530 of one night side and people were 225 00:09:05,260 --> 00:09:02,120 worried about what would happen to your 226 00:09:08,560 --> 00:09:05,270 planet planet's atmosphere so back about 227 00:09:10,360 --> 00:09:08,570 15 years ago or so there was this 228 00:09:12,670 --> 00:09:10,370 meeting that I mentioned that was all 229 00:09:14,430 --> 00:09:12,680 about reevaluating them and it turns out 230 00:09:18,160 --> 00:09:14,440 that none of those things are really 231 00:09:20,080 --> 00:09:18,170 showstoppers you know even though it is 232 00:09:22,000 --> 00:09:20,090 definitely something for us to take into 233 00:09:24,670 --> 00:09:22,010 account that they are subject to this 234 00:09:27,280 --> 00:09:24,680 high-energy radiation it also could be 235 00:09:29,890 --> 00:09:27,290 beneficial in certain ways so maybe you 236 00:09:31,510 --> 00:09:29,900 have a very massive planet or with a 237 00:09:33,490 --> 00:09:31,520 very thick atmosphere that wouldn't be 238 00:09:35,230 --> 00:09:33,500 habitable in the way that we think of it 239 00:09:37,420 --> 00:09:35,240 and maybe that stellar activity actually 240 00:09:39,010 --> 00:09:37,430 erodes some of it often leaves you with 241 00:09:41,020 --> 00:09:39,020 a potentially happen habitable 242 00:09:44,230 --> 00:09:41,030 atmosphere afterwards so there's all 243 00:09:46,240 --> 00:09:44,240 this like open questions about how 244 00:09:48,310 --> 00:09:46,250 exactly the stars influence the planets 245 00:09:50,980 --> 00:09:48,320 and I kind of look into that by studying 246 00:09:52,270 --> 00:09:50,990 the stars themselves very cool I mean if 247 00:09:53,860 --> 00:09:52,280 there's any lesson that we can learn 248 00:09:56,230 --> 00:09:53,870 from life on earth is that life is 249 00:09:57,940 --> 00:09:56,240 extremely adaptable it can find any 250 00:10:00,040 --> 00:09:57,950 place to garner energy from the 251 00:10:01,300 --> 00:10:00,050 environment it will we find life on 252 00:10:01,960 --> 00:10:01,310 Earth and some of the most extreme 253 00:10:05,650 --> 00:10:01,970 conditions 254 00:10:08,320 --> 00:10:05,660 sure watching please don't forget to ask 255 00:10:10,750 --> 00:10:08,330 questions on cigarettes on Facebook and 256 00:10:12,100 --> 00:10:10,760 on Twitter use hash tag ask astrobiology 257 00:10:14,500 --> 00:10:12,110 on Twitter so you're sure to find you 258 00:10:16,900 --> 00:10:14,510 and yeah yeah keep them coming we have a 259 00:10:18,190 --> 00:10:16,910 nice list going on now which is great so 260 00:10:20,950 --> 00:10:18,200 you mentioned Kepler is a really 261 00:10:23,950 --> 00:10:20,960 exciting mission that was launched in 262 00:10:26,110 --> 00:10:23,960 early in mid-2000s to detect the 263 00:10:27,790 --> 00:10:26,120 presence of these extrasolar planets so 264 00:10:29,560 --> 00:10:27,800 planets are orbiting stars that are not 265 00:10:30,850 --> 00:10:29,570 our Sun can you tell us that had been 266 00:10:33,400 --> 00:10:30,860 involved with the entire mission how 267 00:10:34,930 --> 00:10:33,410 successful how successful it was and 268 00:10:37,180 --> 00:10:34,940 perhaps do we have a sense of how many 269 00:10:38,830 --> 00:10:37,190 planets out there that are that could 270 00:10:40,330 --> 00:10:38,840 potentially host life that are within 271 00:10:44,230 --> 00:10:40,340 that habitable zone you were talking 272 00:10:47,470 --> 00:10:44,240 about yeah I think Kepler has been a 273 00:10:49,330 --> 00:10:47,480 greater success than anyone ever thought 274 00:10:51,460 --> 00:10:49,340 it would be with the possible exception 275 00:10:54,040 --> 00:10:51,470 of its principal investigator bill 276 00:10:55,950 --> 00:10:54,050 Baruch II who I often like to tell 277 00:11:00,850 --> 00:10:55,960 people as kind of a lesson about 278 00:11:02,980 --> 00:11:00,860 resilience that bill Borucki posted like 279 00:11:06,340 --> 00:11:02,990 a wrote a paper that had the initial 280 00:11:08,230 --> 00:11:06,350 idea for Kepler 25 years almost to the 281 00:11:11,079 --> 00:11:08,240 day prior to Kepler launch 282 00:11:13,090 --> 00:11:11,089 and he was convinced that it was a good 283 00:11:16,750 --> 00:11:13,100 idea and you know like back in the mid 284 00:11:18,310 --> 00:11:16,760 80s when he wrote the paper people were 285 00:11:19,870 --> 00:11:18,320 right that like the technology wasn't 286 00:11:23,079 --> 00:11:19,880 good enough but the technology caught up 287 00:11:25,600 --> 00:11:23,089 so you know being part of Kepler was 288 00:11:27,130 --> 00:11:25,610 really incredible because of the you 289 00:11:28,840 --> 00:11:27,140 know many thousands of planets that we 290 00:11:30,790 --> 00:11:28,850 now know around other stars I think 291 00:11:33,820 --> 00:11:30,800 we're at you know ballpark four thousand 292 00:11:36,160 --> 00:11:33,830 planets or so in the previous 22 years 293 00:11:38,889 --> 00:11:36,170 to Kepler there were only about 400 of 294 00:11:42,460 --> 00:11:38,899 them known and they tended to be these 295 00:11:45,400 --> 00:11:42,470 like larger usually like a gas giant or 296 00:11:47,350 --> 00:11:45,410 icy giant planets you know but often 297 00:11:50,320 --> 00:11:47,360 very not icy because they were often 298 00:11:52,930 --> 00:11:50,330 very close to their star places that you 299 00:11:54,730 --> 00:11:52,940 know are interesting to find but we're 300 00:11:57,610 --> 00:11:54,740 not necessarily the places we might look 301 00:12:00,850 --> 00:11:57,620 for life not the small rocky worlds like 302 00:12:03,699 --> 00:12:00,860 the Mars's and Venus's and earths of of 303 00:12:06,400 --> 00:12:03,709 the universe so you know Kepler was 304 00:12:09,340 --> 00:12:06,410 revolutionary because it not only found 305 00:12:12,250 --> 00:12:09,350 lots of planets but it was our first way 306 00:12:15,010 --> 00:12:12,260 of looking into how common these smaller 307 00:12:17,170 --> 00:12:15,020 potentially habitable worlds are around 308 00:12:20,130 --> 00:12:17,180 other stars and what we find is that 309 00:12:24,040 --> 00:12:20,140 they're incredibly common you know a 310 00:12:27,340 --> 00:12:24,050 very large fraction of the stars that we 311 00:12:29,139 --> 00:12:27,350 have searched so far you know Kepler was 312 00:12:31,030 --> 00:12:29,149 sort of like taking a little mini census 313 00:12:33,730 --> 00:12:31,040 so it only looked at one patch of the 314 00:12:36,490 --> 00:12:33,740 sky about the size of your palm held out 315 00:12:38,050 --> 00:12:36,500 at arm's length and it counted up all 316 00:12:40,600 --> 00:12:38,060 the planets they could find in that one 317 00:12:42,850 --> 00:12:40,610 patch of sky and then because that Patra 318 00:12:45,579 --> 00:12:42,860 sky is not any you know particularly 319 00:12:47,560 --> 00:12:45,589 special patch of sky it allows us to 320 00:12:50,380 --> 00:12:47,570 extrapolate how many planets we would 321 00:12:52,360 --> 00:12:50,390 expect over the sky as a whole so if you 322 00:12:53,710 --> 00:12:52,370 want to go you know make your neighbors 323 00:12:55,660 --> 00:12:53,720 think you're weird but also have some 324 00:12:59,170 --> 00:12:55,670 fun tonight you can try paneling the 325 00:13:00,760 --> 00:12:59,180 entire night sky with your palm because 326 00:13:02,230 --> 00:13:00,770 it's the thousands of planets that we 327 00:13:03,880 --> 00:13:02,240 found from Kepler are just in that one 328 00:13:07,690 --> 00:13:03,890 patch and that tells us that there must 329 00:13:09,880 --> 00:13:07,700 be billions of planets in the galaxy 330 00:13:11,680 --> 00:13:09,890 itself and I'll point out that one of 331 00:13:13,900 --> 00:13:11,690 even though Kepler was focused on 332 00:13:16,600 --> 00:13:13,910 looking at stars that were more massive 333 00:13:19,240 --> 00:13:16,610 like our Sun one of Kepler's main 334 00:13:22,060 --> 00:13:19,250 results is that it is actually the low 335 00:13:23,740 --> 00:13:22,070 mass stars that seem to 336 00:13:27,610 --> 00:13:23,750 least frequent more frequently have 337 00:13:30,250 --> 00:13:27,620 small rocky worlds that are in this 338 00:13:33,100 --> 00:13:30,260 potential habitable zone so that tells 339 00:13:35,760 --> 00:13:33,110 us that by the numbers the small red 340 00:13:38,140 --> 00:13:35,770 stars are really the place to look very 341 00:13:39,730 --> 00:13:38,150 cool so it's just them the numbers alone 342 00:13:42,070 --> 00:13:39,740 like billions of stars in our galaxy 343 00:13:43,840 --> 00:13:42,080 each have several planets you know it 344 00:13:46,570 --> 00:13:43,850 means perhaps tens of billions of 345 00:13:47,890 --> 00:13:46,580 planets in our own galaxy alone it seems 346 00:13:50,530 --> 00:13:47,900 very difficult to think that we're the 347 00:13:54,280 --> 00:13:50,540 only life in this in this in this world 348 00:13:56,470 --> 00:13:54,290 wow just mind-blowing numbers and what's 349 00:13:57,250 --> 00:13:56,480 cool also is that like even in our own 350 00:14:00,040 --> 00:13:57,260 solar system 351 00:14:01,660 --> 00:14:00,050 humans are searching for life beyond the 352 00:14:04,270 --> 00:14:01,670 habitable zone right the I have the 353 00:14:06,670 --> 00:14:04,280 moons of Saturn and Jupiter who have 354 00:14:08,320 --> 00:14:06,680 sort of moon Enceladus for example is 355 00:14:10,240 --> 00:14:08,330 the moon of Saturn and Europe moon of 356 00:14:11,740 --> 00:14:10,250 Jupiter are thought to potentially 357 00:14:14,020 --> 00:14:11,750 Harbor environments that could sustain 358 00:14:16,060 --> 00:14:14,030 life right under the ice shelves where 359 00:14:19,240 --> 00:14:16,070 water is interacting with rocks so our 360 00:14:20,860 --> 00:14:19,250 own solar system hosts environments that 361 00:14:22,360 --> 00:14:20,870 could host life beyond the traditional 362 00:14:23,890 --> 00:14:22,370 concept of our habitable zone so 363 00:14:26,620 --> 00:14:23,900 jester's increases the numbers of 364 00:14:30,370 --> 00:14:26,630 potential habitable worlds to are 365 00:14:31,780 --> 00:14:30,380 stagnant absolutely and you know I as a 366 00:14:33,730 --> 00:14:31,790 person who kind of came into 367 00:14:36,850 --> 00:14:33,740 astrobiology from an astronomy 368 00:14:39,910 --> 00:14:36,860 perspective I think my thinking in 369 00:14:41,680 --> 00:14:39,920 recent years has shifted about where we 370 00:14:43,420 --> 00:14:41,690 might find the and this is like one of 371 00:14:46,810 --> 00:14:43,430 my favorite questions to ask people so 372 00:14:49,570 --> 00:14:46,820 they'll ask you a question but you know 373 00:14:52,570 --> 00:14:49,580 I often like asking people do you think 374 00:14:55,120 --> 00:14:52,580 that we'll find the first unambiguous 375 00:14:57,930 --> 00:14:55,130 sign of life you know the thing that 376 00:15:00,010 --> 00:14:57,940 people kind of come together and accept 377 00:15:02,250 --> 00:15:00,020 rather than arguing over although 378 00:15:04,690 --> 00:15:02,260 scientists always argue over a results 379 00:15:06,640 --> 00:15:04,700 you know do you think that will be in 380 00:15:08,680 --> 00:15:06,650 the solar system or outside the solar 381 00:15:11,410 --> 00:15:08,690 system because I think I used to think 382 00:15:13,240 --> 00:15:11,420 it would be from some of the atmospheric 383 00:15:15,580 --> 00:15:13,250 characterization of exoplanets that 384 00:15:17,860 --> 00:15:15,590 we've been you know working towards and 385 00:15:19,900 --> 00:15:17,870 trying to understand what those signs 386 00:15:21,550 --> 00:15:19,910 those global signs of life that we might 387 00:15:24,430 --> 00:15:21,560 measure in the atmospheres of planets 388 00:15:27,070 --> 00:15:24,440 are but the more I think about it 389 00:15:29,410 --> 00:15:27,080 because there are so many potentially 390 00:15:31,780 --> 00:15:29,420 habitable places in our own solar system 391 00:15:33,520 --> 00:15:31,790 that are not amenable to that kind of 392 00:15:35,770 --> 00:15:33,530 characterization at all you know 393 00:15:37,210 --> 00:15:35,780 Europa's ocean being a great one 394 00:15:38,740 --> 00:15:37,220 you know like there's no there's no 395 00:15:40,210 --> 00:15:38,750 atmosphere you're like you can't use any 396 00:15:42,940 --> 00:15:40,220 of the techniques that you would use on 397 00:15:46,350 --> 00:15:42,950 an exoplanet on something like Europa or 398 00:15:49,600 --> 00:15:46,360 even like Titan or even subsurface Mars 399 00:15:52,240 --> 00:15:49,610 so you know I I think my thinking has 400 00:15:53,890 --> 00:15:52,250 actually kind of changed over to being 401 00:15:56,770 --> 00:15:53,900 like well I think we should look in all 402 00:15:58,540 --> 00:15:56,780 places maybe the first unambiguous thing 403 00:16:00,820 --> 00:15:58,550 the thing that really like we're like oh 404 00:16:02,170 --> 00:16:00,830 yeah no that's a sign of life might 405 00:16:05,110 --> 00:16:02,180 actually just be here in our solar 406 00:16:06,880 --> 00:16:05,120 system yeah and you know frankly the 407 00:16:08,710 --> 00:16:06,890 first few astrobiologists are going to 408 00:16:10,720 --> 00:16:08,720 be landing on Mars in the in the next 409 00:16:13,150 --> 00:16:10,730 few decades might be the ones with the 410 00:16:15,070 --> 00:16:13,160 help of robots actually detect that kind 411 00:16:17,140 --> 00:16:15,080 of potential life-forms who knows 412 00:16:19,090 --> 00:16:17,150 although the Martian surface is pretty 413 00:16:21,700 --> 00:16:19,100 deadly for life as we know it but as we 414 00:16:24,100 --> 00:16:21,710 know life is very very flexible in ways 415 00:16:25,870 --> 00:16:24,110 to to find hiding spots and ways to 416 00:16:27,040 --> 00:16:25,880 extract energy from the environments so 417 00:16:27,910 --> 00:16:27,050 let's talk about Mars a little bit 418 00:16:29,500 --> 00:16:27,920 that's something I know you've been 419 00:16:31,990 --> 00:16:29,510 talking about especially with human 420 00:16:33,580 --> 00:16:32,000 explorers you hosted a workshop not too 421 00:16:34,960 --> 00:16:33,590 long ago about thinking about the kind 422 00:16:38,170 --> 00:16:34,970 of the longer-term questions about 423 00:16:39,910 --> 00:16:38,180 Humanity on Mars of arguments I've seen 424 00:16:43,450 --> 00:16:39,920 the press is that human humanity should 425 00:16:46,390 --> 00:16:43,460 learn how to explore and conquer almost 426 00:16:48,340 --> 00:16:46,400 settle Mars as a backup in case we screw 427 00:16:49,960 --> 00:16:48,350 up our own planet that's something I 428 00:16:51,700 --> 00:16:49,970 personally feel strongly against and 429 00:16:53,620 --> 00:16:51,710 that kind of philosophy and I think you 430 00:16:55,600 --> 00:16:53,630 have some similar viewpoints you tell us 431 00:16:58,329 --> 00:16:55,610 more but but how you approach the human 432 00:17:01,030 --> 00:16:58,339 settlement of Mars yeah you know for the 433 00:17:03,160 --> 00:17:01,040 past for the past several years I've 434 00:17:05,470 --> 00:17:03,170 really been very interested in some of 435 00:17:08,500 --> 00:17:05,480 these like sociological questions about 436 00:17:10,720 --> 00:17:08,510 not just you know how we plan for space 437 00:17:12,579 --> 00:17:10,730 missions but also like how we talk about 438 00:17:14,319 --> 00:17:12,589 what it is that we're doing like the 439 00:17:17,140 --> 00:17:14,329 narratives that we tell in the way that 440 00:17:18,490 --> 00:17:17,150 we frame space exploration particularly 441 00:17:20,890 --> 00:17:18,500 when we're talking about human beings 442 00:17:23,410 --> 00:17:20,900 going into space and what you know 443 00:17:26,380 --> 00:17:23,420 projects they might do they're you know 444 00:17:29,410 --> 00:17:26,390 my my interest in the topic was really 445 00:17:35,080 --> 00:17:29,420 in some ways sparked by being very 446 00:17:36,670 --> 00:17:35,090 annoyed by those those what I think are 447 00:17:38,680 --> 00:17:36,680 really like marketing narratives that 448 00:17:42,820 --> 00:17:38,690 come out of a lot of private space 449 00:17:46,390 --> 00:17:42,830 industry about how going to Mars will 450 00:17:49,270 --> 00:17:46,400 somehow like back up humanity or you 451 00:17:52,780 --> 00:17:49,280 know allow us as some sort of like you 452 00:17:54,340 --> 00:17:52,790 get out of jail free card for the kinds 453 00:17:57,160 --> 00:17:54,350 of things that we're wreaking on our own 454 00:18:00,630 --> 00:17:57,170 environment here and you know I think 455 00:18:05,830 --> 00:18:00,640 like as much as I love space exploration 456 00:18:09,040 --> 00:18:05,840 the the nicest day on Mars it's still an 457 00:18:12,820 --> 00:18:09,050 extremely inhospitable environment and 458 00:18:14,680 --> 00:18:12,830 not only that you know the fact that we 459 00:18:18,340 --> 00:18:14,690 have the planet that we do and that we 460 00:18:20,560 --> 00:18:18,350 have resources to the point where we can 461 00:18:22,720 --> 00:18:20,570 think about literally blasting those 462 00:18:25,210 --> 00:18:22,730 resources using those resources to send 463 00:18:27,040 --> 00:18:25,220 things off of space now off of the you 464 00:18:30,580 --> 00:18:27,050 know the rock that we live on into space 465 00:18:33,190 --> 00:18:30,590 you know a lot of our even ability to 466 00:18:35,350 --> 00:18:33,200 consider thinking about the way the 467 00:18:37,510 --> 00:18:35,360 universe works and space exploration is 468 00:18:40,870 --> 00:18:37,520 given to us by having a planet that 469 00:18:44,460 --> 00:18:40,880 supports at least our basic needs in a 470 00:18:47,770 --> 00:18:44,470 variety of ways so you know I think that 471 00:18:50,950 --> 00:18:47,780 these sort of invocations of existential 472 00:18:54,570 --> 00:18:50,960 dread about like asteroid impacts you 473 00:18:58,630 --> 00:18:54,580 know going to like dinosaurus basically 474 00:19:01,090 --> 00:18:58,640 are are a little disingenuous especially 475 00:19:04,000 --> 00:19:01,100 because you know many of those companies 476 00:19:06,790 --> 00:19:04,010 that have been I think most responsible 477 00:19:08,890 --> 00:19:06,800 for forwarding that narrative never 478 00:19:11,200 --> 00:19:08,900 bring up climate change because it in in 479 00:19:13,120 --> 00:19:11,210 it actually implies like a personal 480 00:19:14,710 --> 00:19:13,130 responsibility to deal with stuff here 481 00:19:16,600 --> 00:19:14,720 on earth whereas if you say it's an 482 00:19:18,340 --> 00:19:16,610 asteroid impact you're you're predicting 483 00:19:21,460 --> 00:19:18,350 protecting yourself from wealth and 484 00:19:23,290 --> 00:19:21,470 that's nobody's fault right so you know 485 00:19:26,890 --> 00:19:23,300 I think out of that I became very 486 00:19:28,840 --> 00:19:26,900 interested in you know not only like the 487 00:19:31,780 --> 00:19:28,850 ways we justify going to space but then 488 00:19:34,810 --> 00:19:31,790 also the ways that we invoke narratives 489 00:19:38,050 --> 00:19:34,820 from human history so you know even the 490 00:19:42,970 --> 00:19:38,060 choice of the word like colonization you 491 00:19:46,150 --> 00:19:42,980 know conquering settling you know broad 492 00:19:49,240 --> 00:19:46,160 declarations of like what what humans do 493 00:19:52,060 --> 00:19:49,250 and like you know humans need to leave 494 00:19:54,750 --> 00:19:52,070 their territory etc a lot of those come 495 00:19:57,850 --> 00:19:54,760 from you know the history of 496 00:19:59,620 --> 00:19:57,860 predominantly European colonization and 497 00:20:01,030 --> 00:19:59,630 a lot of those narratives are drawn like 498 00:20:02,070 --> 00:20:01,040 specifically tied to things like 499 00:20:05,149 --> 00:20:02,080 Columbus 500 00:20:08,070 --> 00:20:05,159 and you know to me that is a symptom of 501 00:20:12,659 --> 00:20:08,080 a broader lack of inclusion in the 502 00:20:14,399 --> 00:20:12,669 fields you know I think for those of us 503 00:20:16,529 --> 00:20:14,409 who are within the field who are like of 504 00:20:19,049 --> 00:20:16,539 your European descent 505 00:20:21,570 --> 00:20:19,059 we don't necessarily hear the name 506 00:20:23,310 --> 00:20:21,580 Columbus and think about genocide but 507 00:20:25,860 --> 00:20:23,320 that is the historical narrative that 508 00:20:28,649 --> 00:20:25,870 we're drawing on and so you know I would 509 00:20:31,740 --> 00:20:28,659 like us to ask what are the ways in 510 00:20:33,810 --> 00:20:31,750 which we use these narratives and you 511 00:20:36,080 --> 00:20:33,820 know like are they a what we want to do 512 00:20:39,899 --> 00:20:36,090 what we want to use to frame the future 513 00:20:42,570 --> 00:20:39,909 and also you know what rewriting of 514 00:20:45,509 --> 00:20:42,580 Earth's history are we implying by 515 00:20:49,740 --> 00:20:45,519 casting them in this supposedly neutral 516 00:20:52,100 --> 00:20:49,750 or and/or positive light so over the 517 00:20:54,090 --> 00:20:52,110 past year or several years and 518 00:20:56,009 --> 00:20:54,100 specifically at the Library of Congress 519 00:20:59,009 --> 00:20:56,019 what I was doing was looking at a lot of 520 00:21:01,529 --> 00:20:59,019 the intersections of things we explore 521 00:21:04,139 --> 00:21:01,539 here on earth and you know art history 522 00:21:07,289 --> 00:21:04,149 so not just for example colonization but 523 00:21:10,470 --> 00:21:07,299 also environmental law the way that we 524 00:21:12,539 --> 00:21:10,480 think about environments and whether 525 00:21:14,120 --> 00:21:12,549 they are for the use of humanity whether 526 00:21:16,200 --> 00:21:14,130 they have sovereignty unto themselves 527 00:21:18,120 --> 00:21:16,210 whether their sovereignty or their 528 00:21:19,470 --> 00:21:18,130 autonomy has tied to the presence of 529 00:21:21,450 --> 00:21:19,480 life which i think is a really 530 00:21:23,129 --> 00:21:21,460 interesting question too and the way 531 00:21:25,230 --> 00:21:23,139 that that interfaces with things like 532 00:21:28,379 --> 00:21:25,240 our laws you know like our planetary 533 00:21:30,450 --> 00:21:28,389 protection policies for example the way 534 00:21:32,879 --> 00:21:30,460 we clean our spacecraft when we go to 535 00:21:35,490 --> 00:21:32,889 try and find life so yeah I've been 536 00:21:36,840 --> 00:21:35,500 thinking about all of that and it's 537 00:21:38,610 --> 00:21:36,850 really valuable cause I mean clearly 538 00:21:41,370 --> 00:21:38,620 Humanity is more advanced in the 539 00:21:43,680 --> 00:21:41,380 engineering and in technology of landing 540 00:21:46,080 --> 00:21:43,690 a craft on another planet then we are 541 00:21:48,360 --> 00:21:46,090 about the environmental science about 542 00:21:50,879 --> 00:21:48,370 the ethics about the the legal about the 543 00:21:54,360 --> 00:21:50,889 economics so I wonder if there's value 544 00:21:57,210 --> 00:21:54,370 in and just like slowing down the human 545 00:21:59,580 --> 00:21:57,220 push to put humans on Mars until we're 546 00:22:02,279 --> 00:21:59,590 able to put as much financial resources 547 00:22:04,440 --> 00:22:02,289 into these soft Sciences to to really 548 00:22:06,360 --> 00:22:04,450 not screw up when we settle another 549 00:22:08,700 --> 00:22:06,370 world and not make the mistakes of our 550 00:22:11,370 --> 00:22:08,710 past yeah well and I think that one of 551 00:22:13,200 --> 00:22:11,380 the things that I I personally have 552 00:22:15,840 --> 00:22:13,210 really enjoyed about doing some of this 553 00:22:18,359 --> 00:22:15,850 work is the way that it's allowed me to 554 00:22:21,659 --> 00:22:18,369 reach out to and to learn from scholars 555 00:22:24,210 --> 00:22:21,669 so for example scholars who are you know 556 00:22:25,940 --> 00:22:24,220 in indigenous history who could talk 557 00:22:29,969 --> 00:22:25,950 about treaty making and the ways 558 00:22:32,639 --> 00:22:29,979 treaties tend to become violated or be 559 00:22:34,950 --> 00:22:32,649 violated by nations and private actors 560 00:22:37,919 --> 00:22:34,960 when resources come into play which is 561 00:22:40,139 --> 00:22:37,929 exactly what we are seeing starting to 562 00:22:43,289 --> 00:22:40,149 happen with talk about you know like 563 00:22:44,700 --> 00:22:43,299 mining in space and like the treaties 564 00:22:47,700 --> 00:22:44,710 that we have like the Outer Space Treaty 565 00:22:50,009 --> 00:22:47,710 of 1967 we can learn a lot by talking 566 00:22:53,190 --> 00:22:50,019 with people who have studied these same 567 00:22:55,320 --> 00:22:53,200 kinds of cases in fields that are 568 00:22:57,690 --> 00:22:55,330 seemingly disparate from science and so 569 00:23:01,379 --> 00:22:57,700 you know this is again another way in 570 00:23:03,029 --> 00:23:01,389 which astrobiology is a wonderful 571 00:23:04,979 --> 00:23:03,039 conduit for being a truly 572 00:23:07,169 --> 00:23:04,989 interdisciplinary not just science but 573 00:23:09,269 --> 00:23:07,179 an interdisciplinary field and I've 574 00:23:12,659 --> 00:23:09,279 really learned a lot from you know folks 575 00:23:14,909 --> 00:23:12,669 who are in sociology or ethicists who 576 00:23:17,389 --> 00:23:14,919 are now even you know people in animal 577 00:23:20,639 --> 00:23:17,399 behavior who are now like working with 578 00:23:22,710 --> 00:23:20,649 you know people within astrobiology 579 00:23:25,919 --> 00:23:22,720 to try and understand what some of these 580 00:23:27,409 --> 00:23:25,929 issues are and and really broaden our 581 00:23:29,729 --> 00:23:27,419 thinking you know I think having more 582 00:23:32,909 --> 00:23:29,739 voices in the room has been really 583 00:23:34,799 --> 00:23:32,919 helpful you know coming out of my year 584 00:23:36,989 --> 00:23:34,809 at the Library of Congress one of the 585 00:23:40,200 --> 00:23:36,999 the things that I've been engaged in 586 00:23:42,570 --> 00:23:40,210 over the past about half a year or so I 587 00:23:45,210 --> 00:23:42,580 guess just at the end of 2018 is that I 588 00:23:47,519 --> 00:23:45,220 and another astronomer Erica ness fold 589 00:23:50,549 --> 00:23:47,529 who is now also a developer for universe 590 00:23:52,889 --> 00:23:50,559 sandbox co-founded space ethics 591 00:23:56,279 --> 00:23:52,899 nonprofit called the just space Alliance 592 00:23:59,190 --> 00:23:56,289 and essentially what we are here to do 593 00:24:02,369 --> 00:23:59,200 is to help advocate for a more inclusive 594 00:24:04,379 --> 00:24:02,379 and ethical future in space a more 595 00:24:07,289 --> 00:24:04,389 inclusive approach to space exploration 596 00:24:09,839 --> 00:24:07,299 and also to use some of the excitement 597 00:24:11,940 --> 00:24:09,849 that people have to talk about how we 598 00:24:14,940 --> 00:24:11,950 might create more equitable equitable 599 00:24:16,799 --> 00:24:14,950 futures here on earth today because a 600 00:24:18,719 --> 00:24:16,809 lot of times when we talk about what 601 00:24:20,639 --> 00:24:18,729 humans might do in space what we're 602 00:24:23,729 --> 00:24:20,649 really talking about is the ways in 603 00:24:26,099 --> 00:24:23,739 which we hope or fear that we might live 604 00:24:29,279 --> 00:24:26,109 on earth and so I think it's a really 605 00:24:29,580 --> 00:24:29,289 fertile ground for creating some visions 606 00:24:31,730 --> 00:24:29,590 of the 607 00:24:35,130 --> 00:24:31,740 future that are maybe a little more 608 00:24:37,620 --> 00:24:35,140 inclusive than they have been I really 609 00:24:39,960 --> 00:24:37,630 hope that this vision of it comes comes 610 00:24:41,880 --> 00:24:39,970 comes through like even even the 611 00:24:44,430 --> 00:24:41,890 diversity of scientists needed to 612 00:24:45,960 --> 00:24:44,440 advance as questions is coupled to the 613 00:24:49,320 --> 00:24:45,970 diversity of the scientists themselves 614 00:24:50,190 --> 00:24:49,330 in the discipline to advance on because 615 00:24:52,279 --> 00:24:50,200 we gain a lot from different 616 00:24:55,680 --> 00:24:52,289 perspectives and from different culture 617 00:25:01,740 --> 00:24:55,690 absolutely um so as far as I can tell 618 00:25:04,590 --> 00:25:01,750 you've given to TED talks and I think 619 00:25:06,389 --> 00:25:04,600 your second one you ended on about you 620 00:25:08,399 --> 00:25:06,399 ended the talk talking about the the 621 00:25:11,430 --> 00:25:08,409 Fermi paradox thinking about the 622 00:25:12,539 --> 00:25:11,440 long-term survivability of humans you 623 00:25:14,460 --> 00:25:12,549 know it's something we need to be very 624 00:25:16,580 --> 00:25:14,470 attentive to because you know our 625 00:25:18,419 --> 00:25:16,590 civilization has been listening through 626 00:25:20,399 --> 00:25:18,429 efforts like SETI the search for 627 00:25:22,799 --> 00:25:20,409 extraterrestrial intelligence for radio 628 00:25:25,350 --> 00:25:22,809 signals coming from space for 50 years 629 00:25:27,570 --> 00:25:25,360 and we have we have heard nothing right 630 00:25:29,370 --> 00:25:27,580 so one of the resolutions of these Fermi 631 00:25:31,769 --> 00:25:29,380 paradox is that civilizations once it 632 00:25:33,779 --> 00:25:31,779 become advanced enough miss the 633 00:25:35,850 --> 00:25:33,789 opportunity to see themselves from space 634 00:25:38,730 --> 00:25:35,860 and realize the fragility you end up you 635 00:25:40,289 --> 00:25:38,740 know killing their civilization so 636 00:25:42,720 --> 00:25:40,299 that's not a destiny I hope for our 637 00:25:44,610 --> 00:25:42,730 society and so let's talk a little bit 638 00:25:45,539 --> 00:25:44,620 more about this these SETI efforts 639 00:25:47,820 --> 00:25:45,549 because it's something that I know 640 00:25:50,760 --> 00:25:47,830 you've been involved with as well and 641 00:25:53,130 --> 00:25:50,770 the efforts up to date have been trying 642 00:25:56,159 --> 00:25:53,140 to figure out how to characterize the 643 00:25:57,529 --> 00:25:56,169 signals based on what we think the 644 00:25:59,519 --> 00:25:57,539 expressive as extraterrestrial 645 00:26:01,169 --> 00:25:59,529 civilizations could be sending in terms 646 00:26:02,610 --> 00:26:01,179 of information but you're changing that 647 00:26:06,570 --> 00:26:02,620 paradigm a little bit with your research 648 00:26:09,419 --> 00:26:06,580 right yeah so I been very interested in 649 00:26:12,570 --> 00:26:09,429 SETI kind of as I you know a 650 00:26:14,310 --> 00:26:12,580 complementary fork to what-what I you 651 00:26:16,169 --> 00:26:14,320 know sometimes will call like vanilla 652 00:26:17,669 --> 00:26:16,179 astrobiology you know that the 653 00:26:20,399 --> 00:26:17,679 understanding of the underlying physics 654 00:26:22,830 --> 00:26:20,409 and chemistry and biology is wonderful 655 00:26:25,049 --> 00:26:22,840 and it's it's I think complementary to 656 00:26:26,730 --> 00:26:25,059 doing something like what is now called 657 00:26:28,470 --> 00:26:26,740 like the search for techno signatures 658 00:26:30,060 --> 00:26:28,480 you know the signs of technologically 659 00:26:33,930 --> 00:26:30,070 advanced life that sends signals out 660 00:26:36,360 --> 00:26:33,940 into the universe and you know SETI 661 00:26:39,060 --> 00:26:36,370 it said he is really sociologically 662 00:26:41,370 --> 00:26:39,070 interesting too because while it is true 663 00:26:43,350 --> 00:26:41,380 that efforts have been going on for like 664 00:26:47,940 --> 00:26:43,360 50 some-odd here 665 00:26:51,650 --> 00:26:47,950 study has I think suffered a lack of 666 00:26:54,840 --> 00:26:51,660 support where you know in many ways 667 00:26:57,270 --> 00:26:54,850 doing something like studying extreme 668 00:26:59,370 --> 00:26:57,280 life that lives in acidic pools in 669 00:27:02,400 --> 00:26:59,380 Yellowstone is considered like 670 00:27:04,350 --> 00:27:02,410 legitimate science but looking for radio 671 00:27:06,480 --> 00:27:04,360 signals from space from you know 672 00:27:09,780 --> 00:27:06,490 technologically advanced life has been 673 00:27:12,210 --> 00:27:09,790 considered kind of fringy and so it 674 00:27:15,299 --> 00:27:12,220 hasn't typically enjoyed the same kind 675 00:27:17,610 --> 00:27:15,309 of financial support in terms of ability 676 00:27:19,560 --> 00:27:17,620 to access research funding and support 677 00:27:22,380 --> 00:27:19,570 graduate students or postdocs or even 678 00:27:24,630 --> 00:27:22,390 faculty to work full-time on those 679 00:27:27,450 --> 00:27:24,640 questions and so it is true that we've 680 00:27:30,030 --> 00:27:27,460 been looking for a long time but you 681 00:27:32,010 --> 00:27:30,040 know I think I think it's Jill tarter 682 00:27:34,020 --> 00:27:32,020 who likes to say you know the amount 683 00:27:37,860 --> 00:27:34,030 that we have looked as equivalent to a 684 00:27:40,470 --> 00:27:37,870 cup of water in the ocean you know it it 685 00:27:44,160 --> 00:27:40,480 isn't much of a paradox to me that we 686 00:27:46,710 --> 00:27:44,170 haven't found anything with the efforts 687 00:27:52,500 --> 00:27:46,720 that we've been able to make you know so 688 00:27:55,799 --> 00:27:52,510 I also question our our approach you 689 00:27:58,590 --> 00:27:55,809 know I think many many study efforts for 690 00:28:00,600 --> 00:27:58,600 a very long time work focused on what my 691 00:28:03,200 --> 00:28:00,610 my colleague Jeff Scargill who was at 692 00:28:05,640 --> 00:28:03,210 NASA Ames called psychoanalyzing et 693 00:28:08,100 --> 00:28:05,650 thinking about you know like well if you 694 00:28:09,750 --> 00:28:08,110 were another intelligence like what kind 695 00:28:12,060 --> 00:28:09,760 of signal would you send out that 696 00:28:13,980 --> 00:28:12,070 someone else might be able to detect it 697 00:28:15,900 --> 00:28:13,990 and then also decode it and then what 698 00:28:18,570 --> 00:28:15,910 information would you include in it and 699 00:28:19,830 --> 00:28:18,580 how would you make it different from you 700 00:28:22,080 --> 00:28:19,840 know and astronomically like 701 00:28:25,770 --> 00:28:22,090 naturally-occurring Astrophysical signal 702 00:28:27,270 --> 00:28:25,780 these are all great questions but one of 703 00:28:30,000 --> 00:28:27,280 the things that I'm really interested in 704 00:28:32,210 --> 00:28:30,010 is applications of something called 705 00:28:36,120 --> 00:28:32,220 machine learning to astronomy that 706 00:28:38,549 --> 00:28:36,130 allows you to deal with large large 707 00:28:40,890 --> 00:28:38,559 piles of data data that is of a volume 708 00:28:44,040 --> 00:28:40,900 or complexity that I a human would have 709 00:28:46,950 --> 00:28:44,050 a hard time looking through it I machine 710 00:28:49,919 --> 00:28:46,960 learning is used for a broad variety of 711 00:28:51,780 --> 00:28:49,929 applications in astronomy of which I am 712 00:28:54,810 --> 00:28:51,790 focused on study but that's not the only 713 00:28:56,280 --> 00:28:54,820 thing and I've been very interested in 714 00:28:59,300 --> 00:28:56,290 the ability to look 715 00:29:01,830 --> 00:28:59,310 or signals that are unusual without 716 00:29:04,260 --> 00:29:01,840 having to say how they are unusual 717 00:29:05,730 --> 00:29:04,270 before them because the only thing we 718 00:29:09,630 --> 00:29:05,740 know is that we don't know what we're 719 00:29:11,490 --> 00:29:09,640 looking for you know we don't know if 720 00:29:13,590 --> 00:29:11,500 it's in the data we don't know what it 721 00:29:16,320 --> 00:29:13,600 looks like we don't know anything about 722 00:29:18,690 --> 00:29:16,330 like who might be sending it you know 723 00:29:21,660 --> 00:29:18,700 how they communicate etc like we can't 724 00:29:24,090 --> 00:29:21,670 even talk to wheels okay Whipple's are 725 00:29:25,380 --> 00:29:24,100 are organisms that we understand a lot 726 00:29:26,970 --> 00:29:25,390 about who have like advanced 727 00:29:29,220 --> 00:29:26,980 communications and we cannot communicate 728 00:29:31,140 --> 00:29:29,230 with them so you know we have all of 729 00:29:34,290 --> 00:29:31,150 these things kind of hindering us in the 730 00:29:36,390 --> 00:29:34,300 search for life however what we do have 731 00:29:38,430 --> 00:29:36,400 is a lot of astronomical data now you 732 00:29:41,010 --> 00:29:38,440 know Kepler is an example of an 733 00:29:43,140 --> 00:29:41,020 astronomical survey where instead of you 734 00:29:43,890 --> 00:29:43,150 know like taking data on like one thing 735 00:29:46,710 --> 00:29:43,900 at a time 736 00:29:50,130 --> 00:29:46,720 you take vast amounts of data on many 737 00:29:52,320 --> 00:29:50,140 many objects all at once and that gives 738 00:29:56,310 --> 00:29:52,330 you a big data base in Kepler's case of 739 00:29:58,050 --> 00:29:56,320 how stars vary in brightness and in 740 00:30:00,090 --> 00:29:58,060 Kepler's case like there's been a couple 741 00:30:02,790 --> 00:30:00,100 examples of things that have popped up 742 00:30:05,220 --> 00:30:02,800 in the course of you know Kepler just 743 00:30:07,830 --> 00:30:05,230 doing its planet-hunting job that have 744 00:30:09,840 --> 00:30:07,840 been unusual so Boyajian star is kind of 745 00:30:11,790 --> 00:30:09,850 like the big one of this has made a big 746 00:30:13,770 --> 00:30:11,800 splash a couple of years ago as being 747 00:30:17,730 --> 00:30:13,780 like potential alien mega-structure 748 00:30:20,070 --> 00:30:17,740 found found by citizen scientists 749 00:30:22,380 --> 00:30:20,080 actually looking through the light 750 00:30:23,940 --> 00:30:22,390 curves from Kepler these measurements of 751 00:30:26,280 --> 00:30:23,950 how the brightness of stars are changing 752 00:30:28,140 --> 00:30:26,290 over time and seeing that there was this 753 00:30:32,010 --> 00:30:28,150 unusual one that didn't look like the 754 00:30:33,840 --> 00:30:32,020 rest so that's great but also like what 755 00:30:36,840 --> 00:30:33,850 happens then if you have so much data 756 00:30:39,180 --> 00:30:36,850 that a person would never accidentally 757 00:30:41,160 --> 00:30:39,190 come across that so what I've been 758 00:30:43,230 --> 00:30:41,170 working on with my graduate student 759 00:30:45,420 --> 00:30:43,240 Daniel Giles who is at the Illinois 760 00:30:47,150 --> 00:30:45,430 Institute of Technology is just wrapping 761 00:30:50,760 --> 00:30:47,160 up his thesis work on this actually 762 00:30:53,700 --> 00:30:50,770 using a machine learning to sift the 763 00:30:55,350 --> 00:30:53,710 Kepler data into categories of stars 764 00:30:57,540 --> 00:30:55,360 that resemble each other in their 765 00:31:01,350 --> 00:30:57,550 behavior and what this allows us to do 766 00:31:02,580 --> 00:31:01,360 is find things that are unusual so you 767 00:31:05,520 --> 00:31:02,590 know kind of the end of this we have 768 00:31:07,470 --> 00:31:05,530 like a ranked weirdness score for 769 00:31:07,930 --> 00:31:07,480 everything in the database and we are 770 00:31:09,909 --> 00:31:07,940 able to 771 00:31:13,419 --> 00:31:09,919 pick out the most unusual like herbs 772 00:31:16,779 --> 00:31:13,429 that Kepler has observed and our plan is 773 00:31:21,100 --> 00:31:16,789 to identify those you know finding 774 00:31:24,009 --> 00:31:21,110 something unusual in a database stuff 775 00:31:26,830 --> 00:31:24,019 does not mean it's aliens there's a lot 776 00:31:29,769 --> 00:31:26,840 more work to do to figure out like is it 777 00:31:32,499 --> 00:31:29,779 you know some telescope hiccup is it 778 00:31:35,499 --> 00:31:32,509 like you know you're super interesting 779 00:31:36,999 --> 00:31:35,509 study signal is it like new astrophysics 780 00:31:39,249 --> 00:31:37,009 is a known astrophysics that just 781 00:31:42,340 --> 00:31:39,259 doesn't happen very often but to me all 782 00:31:44,499 --> 00:31:42,350 of those things are interesting so where 783 00:31:45,970 --> 00:31:44,509 as trying to figure out what kind of 784 00:31:47,379 --> 00:31:45,980 signal and alien might send and then 785 00:31:49,029 --> 00:31:47,389 detecting that is kind of like oh you 786 00:31:51,159 --> 00:31:49,039 have a smoking gun 787 00:31:53,019 --> 00:31:51,169 this is just a way of making that 788 00:31:57,279 --> 00:31:53,029 serendipity of finding something truly 789 00:31:59,139 --> 00:31:57,289 truly unusual much more efficient so I'm 790 00:32:01,810 --> 00:31:59,149 I've been really excited to see the 791 00:32:04,180 --> 00:32:01,820 progress over the past couple years here 792 00:32:07,149 --> 00:32:04,190 and Daniel just presented some of his 793 00:32:09,549 --> 00:32:07,159 work at apps icon but yeah it's it's 794 00:32:11,169 --> 00:32:09,559 been really fun to work on very cool 795 00:32:13,060 --> 00:32:11,179 very cool I'm excited to see those 796 00:32:14,980 --> 00:32:13,070 results myself I wouldn't be mindful of 797 00:32:16,240 --> 00:32:14,990 time because we definitely wanna give 798 00:32:18,100 --> 00:32:16,250 some time to our audience to ask 799 00:32:20,169 --> 00:32:18,110 questions I'm gonna ask you one last 800 00:32:21,700 --> 00:32:20,179 questions before we open it up and that 801 00:32:23,049 --> 00:32:21,710 is I know you're very accomplished 802 00:32:24,340 --> 00:32:23,059 artist as well could you tell us a 803 00:32:25,869 --> 00:32:24,350 little bit how your art influences 804 00:32:29,289 --> 00:32:25,879 influences your science and perhaps our 805 00:32:31,450 --> 00:32:29,299 your science influences uark sure the 806 00:32:35,019 --> 00:32:31,460 the short answer is that sometimes it 807 00:32:38,710 --> 00:32:35,029 does and sometimes it doesn't so I I do 808 00:32:40,360 --> 00:32:38,720 a pretty wide variety of art work some 809 00:32:43,990 --> 00:32:40,370 of the the things that I've done that 810 00:32:47,320 --> 00:32:44,000 have been more focused on science I I 811 00:32:51,190 --> 00:32:47,330 drew a lot of inspiration from friends 812 00:32:52,840 --> 00:32:51,200 who work with data as a medium so in 813 00:32:55,029 --> 00:32:52,850 particular an artist named Julie 814 00:32:58,299 --> 00:32:55,039 Friedman whose website is translating 815 00:33:00,430 --> 00:32:58,309 nature has a lot of work that she does 816 00:33:02,950 --> 00:33:00,440 in which she takes data and turns it 817 00:33:05,860 --> 00:33:02,960 into you know either in some cases 818 00:33:09,610 --> 00:33:05,870 sculptures in some kind of cases you 819 00:33:11,350 --> 00:33:09,620 know visualizations and also an artist 820 00:33:13,509 --> 00:33:11,360 named Natalie me Bach who uses their 821 00:33:16,119 --> 00:33:13,519 data to create like giant woven 822 00:33:18,100 --> 00:33:16,129 sculptures I encountering a couple of 823 00:33:19,690 --> 00:33:18,110 people like that maybe think about some 824 00:33:22,100 --> 00:33:19,700 of the things that I might do with my 825 00:33:24,380 --> 00:33:22,110 data artistically 826 00:33:27,530 --> 00:33:24,390 several years ago I made a sound 827 00:33:30,530 --> 00:33:27,540 installation where I was taking at the 828 00:33:33,110 --> 00:33:30,540 time I was studying the rotations of 829 00:33:36,740 --> 00:33:33,120 stars and Kepler so stars spin on their 830 00:33:38,540 --> 00:33:36,750 axes like tops and as light and dark 831 00:33:40,910 --> 00:33:38,550 patches on the surface of the star 832 00:33:43,670 --> 00:33:40,920 rotate into and out of you it makes the 833 00:33:45,680 --> 00:33:43,680 light from the star change you can 834 00:33:47,810 --> 00:33:45,690 actually take that measurement that's 835 00:33:50,150 --> 00:33:47,820 actually you know brightness of the star 836 00:33:53,180 --> 00:33:50,160 over time and turn it into sound and it 837 00:33:55,430 --> 00:33:53,190 helps you identify like subtle shifts in 838 00:33:57,620 --> 00:33:55,440 the periodicity that are telling you 839 00:33:59,440 --> 00:33:57,630 something about like where the spots on 840 00:34:02,810 --> 00:33:59,450 the star or peeling are appearing so 841 00:34:05,240 --> 00:34:02,820 that sort of started as Lumi seeing if I 842 00:34:09,080 --> 00:34:05,250 could use sound actually as a way of 843 00:34:10,730 --> 00:34:09,090 exploring my data and then I eventually 844 00:34:14,540 --> 00:34:10,740 ended up deciding that like as an 845 00:34:17,150 --> 00:34:14,550 analysis tool it it wasn't quite what I 846 00:34:19,790 --> 00:34:17,160 wanted it to be and so I ended up making 847 00:34:21,920 --> 00:34:19,800 a sound installation out of it because 848 00:34:23,090 --> 00:34:21,930 you know when we you know if you come to 849 00:34:25,070 --> 00:34:23,100 somewhere like the Adler Planetarium 850 00:34:29,030 --> 00:34:25,080 like we have a lot of like really 851 00:34:31,460 --> 00:34:29,040 beautiful engaging exhibits here but 852 00:34:32,690 --> 00:34:31,470 we're definitely focused also on like 853 00:34:34,910 --> 00:34:32,700 helping you understand like the 854 00:34:37,490 --> 00:34:34,920 underlying science that's happening but 855 00:34:40,610 --> 00:34:37,500 for me one of the powers I think that 856 00:34:42,880 --> 00:34:40,620 art has is of giving people sort of a 857 00:34:45,950 --> 00:34:42,890 more primary emotional experience with 858 00:34:47,960 --> 00:34:45,960 with the work and so you know for me as 859 00:34:50,180 --> 00:34:47,970 a scientist like the exciting part is 860 00:34:51,590 --> 00:34:50,190 when I see that there might be a pattern 861 00:34:54,110 --> 00:34:51,600 in my data and I don't know what it 862 00:34:55,970 --> 00:34:54,120 means yet and like nobody can come to me 863 00:34:59,270 --> 00:34:55,980 and like it read the explanatory plaque 864 00:35:01,310 --> 00:34:59,280 because there isn't one so I really 865 00:35:03,590 --> 00:35:01,320 wanted people to be able to have this 866 00:35:05,330 --> 00:35:03,600 like direct experience with the Kepler 867 00:35:07,910 --> 00:35:05,340 data and just sort of like hear that 868 00:35:09,650 --> 00:35:07,920 there are patterns but not necessarily 869 00:35:11,260 --> 00:35:09,660 to know what they mean but to think 870 00:35:15,110 --> 00:35:11,270 about like what they might mean 871 00:35:16,460 --> 00:35:15,120 so I created a originally it was like a 872 00:35:18,350 --> 00:35:16,470 little installation like a dome 873 00:35:21,760 --> 00:35:18,360 meditation room that you could go into 874 00:35:25,280 --> 00:35:21,770 and then eventually it was up as part of 875 00:35:27,350 --> 00:35:25,290 a group sound exhibit at a gallery 876 00:35:29,570 --> 00:35:27,360 called artists fear outside of 877 00:35:33,290 --> 00:35:29,580 Washington DC called firmata 878 00:35:35,640 --> 00:35:33,300 back I guess in like 2014 or so and yeah 879 00:35:38,819 --> 00:35:35,650 that was really satisfying to 880 00:35:43,319 --> 00:35:38,829 to work on I mean more recently I also 881 00:35:47,099 --> 00:35:43,329 do aerial circus so like I do basically 882 00:35:48,839 --> 00:35:47,109 like performance stuff and I more 883 00:35:50,999 --> 00:35:48,849 recently did something that was only 884 00:35:54,210 --> 00:35:51,009 sort of inspired by astronomy that was 885 00:35:55,829 --> 00:35:54,220 called 40 orbits that was like a kind of 886 00:35:59,670 --> 00:35:55,839 like life story I was my 40th birthday 887 00:36:02,309 --> 00:35:59,680 and January so I asked my partner who is 888 00:36:04,470 --> 00:36:02,319 an artist to compose like a piece of 889 00:36:07,859 --> 00:36:04,480 music like we kind of talked about like 890 00:36:09,180 --> 00:36:07,869 different decades of life and I was 891 00:36:12,239 --> 00:36:09,190 really interested in doing that because 892 00:36:16,019 --> 00:36:12,249 I think the idea that the way we humans 893 00:36:18,799 --> 00:36:16,029 map out time is physically tied to like 894 00:36:21,089 --> 00:36:18,809 the path of our planet around the Sun 895 00:36:23,279 --> 00:36:21,099 you know we have this like actual 896 00:36:25,349 --> 00:36:23,289 physical markers that is tied very much 897 00:36:28,380 --> 00:36:25,359 to like the structure of our solar 898 00:36:31,680 --> 00:36:28,390 system that is how we like map out all 899 00:36:34,529 --> 00:36:31,690 of the sort of non-physical you know 900 00:36:37,950 --> 00:36:34,539 like life things that happen to us 901 00:36:39,569 --> 00:36:37,960 and so maybe I'll tweet that YouTube 902 00:36:40,950 --> 00:36:39,579 video afterwards so I created a 903 00:36:43,799 --> 00:36:40,960 performance and there's like you know 904 00:36:46,650 --> 00:36:43,809 it's pretty pretty fun I'm pretty happy 905 00:36:49,680 --> 00:36:46,660 with how it turned out awesome awesome 906 00:36:52,019 --> 00:36:49,690 yes so all of you are watching dr. Lucy 907 00:36:57,569 --> 00:36:52,029 and Waka wits tweets as at shaka 908 00:36:59,839 --> 00:36:57,579 underscore lulu right okay so now it's 909 00:37:02,400 --> 00:36:59,849 time for questions I'm so excited so 910 00:37:06,120 --> 00:37:02,410 let's go ahead the first question is 911 00:37:08,160 --> 00:37:06,130 from Jim Paz who asks on Twitter I am 912 00:37:09,650 --> 00:37:08,170 curious about your thoughts concerning 913 00:37:11,910 --> 00:37:09,660 the future relationship between 914 00:37:13,349 --> 00:37:11,920 astrobiologists and potential settlers 915 00:37:14,910 --> 00:37:13,359 or miners on the Moon and Mars 916 00:37:18,329 --> 00:37:14,920 can they get along well do you think 917 00:37:21,599 --> 00:37:18,339 there will be a conflict well actually 918 00:37:23,910 --> 00:37:21,609 if you haven't watched it yet NatGeo 919 00:37:27,450 --> 00:37:23,920 channel had it has a show called Mars 920 00:37:30,329 --> 00:37:27,460 that I got to participate in season two 921 00:37:33,059 --> 00:37:30,339 of it's sort of divided between 922 00:37:36,359 --> 00:37:33,069 interviews with folks here on earth like 923 00:37:39,749 --> 00:37:36,369 myself and then the other half of it is 924 00:37:41,849 --> 00:37:39,759 a drama that focuses on a scientific 925 00:37:43,589 --> 00:37:41,859 base on Mars in which miners from 926 00:37:45,900 --> 00:37:43,599 industry show up and the conflicts that 927 00:37:49,460 --> 00:37:45,910 arise from the two of them you know I 928 00:37:54,240 --> 00:37:49,470 think that I don't think that 929 00:37:56,820 --> 00:37:54,250 it's necessarily going to be like all 930 00:37:59,310 --> 00:37:56,830 conflict all the time but I do think 931 00:38:03,480 --> 00:37:59,320 that there are some particular areas of 932 00:38:05,730 --> 00:38:03,490 friction between the motivations of you 933 00:38:08,460 --> 00:38:05,740 know trying to make profit off of a 934 00:38:10,680 --> 00:38:08,470 planet and the motivations of scientists 935 00:38:12,950 --> 00:38:10,690 wanting to study that planet and the way 936 00:38:15,510 --> 00:38:12,960 that this plays out I think most keenly 937 00:38:18,450 --> 00:38:15,520 is when we look at issues of planetary 938 00:38:19,800 --> 00:38:18,460 protection you know the so the Outer 939 00:38:22,980 --> 00:38:19,810 Space Treaty which goes all the way back 940 00:38:25,230 --> 00:38:22,990 to 1967 has this clause in it that says 941 00:38:27,630 --> 00:38:25,240 that you can't contaminate another world 942 00:38:31,230 --> 00:38:27,640 for any reason so you can't make it 943 00:38:33,630 --> 00:38:31,240 unusable to other people and that no 944 00:38:37,350 --> 00:38:33,640 single actor no nation no individual 945 00:38:38,970 --> 00:38:37,360 actor can do that so you know that has 946 00:38:40,770 --> 00:38:38,980 been the law of the land for a very long 947 00:38:43,320 --> 00:38:40,780 time it's like why we clean our 948 00:38:45,020 --> 00:38:43,330 spacecraft when we go to other worlds 949 00:38:47,940 --> 00:38:45,030 and why we're very careful not to 950 00:38:49,760 --> 00:38:47,950 transfer earth bacteria to other 951 00:38:54,300 --> 00:38:49,770 environments within the solar system 952 00:38:55,730 --> 00:38:54,310 however back in 2015 there was something 953 00:38:58,890 --> 00:38:55,740 called the Space Act that was passed 954 00:39:00,780 --> 00:38:58,900 that was motivated largely by the 955 00:39:03,420 --> 00:39:00,790 lobbying efforts of asteroid mining 956 00:39:06,900 --> 00:39:03,430 companies and what the Space Act says is 957 00:39:08,370 --> 00:39:06,910 that you can you can't own a celestial 958 00:39:09,930 --> 00:39:08,380 body so that's another thing that's in 959 00:39:12,960 --> 00:39:09,940 the Outer Space Treaty is that you can't 960 00:39:15,720 --> 00:39:12,970 own another world and you can't own part 961 00:39:17,910 --> 00:39:15,730 of another world so you know like we can 962 00:39:19,680 --> 00:39:17,920 leave all our exploration junk all over 963 00:39:23,130 --> 00:39:19,690 the Moon and Mars but we don't own the 964 00:39:27,300 --> 00:39:23,140 land that that stuff is on even if you 965 00:39:29,430 --> 00:39:27,310 plant a flag in it so you know you can't 966 00:39:32,310 --> 00:39:29,440 own other world still according to the 967 00:39:35,370 --> 00:39:32,320 Space Act however you can own resources 968 00:39:37,920 --> 00:39:35,380 so now space resources are defined as 969 00:39:41,550 --> 00:39:37,930 anything that is not biological 970 00:39:44,430 --> 00:39:41,560 including water that somebody might 971 00:39:46,830 --> 00:39:44,440 extract from another world so this is 972 00:39:49,950 --> 00:39:46,840 very interesting right because the sort 973 00:39:53,490 --> 00:39:49,960 of a casual slogan for astrobiology just 974 00:39:55,020 --> 00:39:53,500 follow the water because you know here 975 00:39:56,640 --> 00:39:55,030 in astrobiology at least than what we've 976 00:39:58,110 --> 00:39:56,650 learned from Earth is that while life 977 00:40:01,080 --> 00:39:58,120 exists in a wide variety of environments 978 00:40:02,910 --> 00:40:01,090 water is a really good sign of like a 979 00:40:04,099 --> 00:40:02,920 place that might be good for life to 980 00:40:06,859 --> 00:40:04,109 throw 981 00:40:08,660 --> 00:40:06,869 for the most part so you know that 982 00:40:11,000 --> 00:40:08,670 brings up like some interesting ethical 983 00:40:14,750 --> 00:40:11,010 questions let's say that what you wanted 984 00:40:17,599 --> 00:40:14,760 to do was create you know a luxury hotel 985 00:40:19,460 --> 00:40:17,609 on Mars and what you'd like to do is 986 00:40:21,800 --> 00:40:19,470 create a waterpark 987 00:40:23,870 --> 00:40:21,810 you know therefore like if you extract 988 00:40:27,079 --> 00:40:23,880 the water for your guests to go to your 989 00:40:29,810 --> 00:40:27,089 luxury hotel on Mars does that mean it's 990 00:40:33,500 --> 00:40:29,820 okay for you to sterilize some water if 991 00:40:35,060 --> 00:40:33,510 there's biology in it do you leave the 992 00:40:38,150 --> 00:40:35,070 biology on the water and just say that 993 00:40:41,510 --> 00:40:38,160 you don't own it you know remember that 994 00:40:42,980 --> 00:40:41,520 we we don't see like giraffes running 995 00:40:44,810 --> 00:40:42,990 across the surface of Mars but that 996 00:40:46,609 --> 00:40:44,820 doesn't mean that there isn't life under 997 00:40:48,440 --> 00:40:46,619 the surface and it doesn't mean that we 998 00:40:51,530 --> 00:40:48,450 might not make some other additional 999 00:40:53,660 --> 00:40:51,540 surprising discoveries so you know I 1000 00:40:57,320 --> 00:40:53,670 think when we play out these scenarios 1001 00:40:59,570 --> 00:40:57,330 of like how private industry versus 1002 00:41:01,760 --> 00:40:59,580 scientific exploration versus like 1003 00:41:05,000 --> 00:41:01,770 nationalistic exploration play out there 1004 00:41:07,550 --> 00:41:05,010 are some obvious errors of areas of 1005 00:41:08,420 --> 00:41:07,560 friction that that come up so these are 1006 00:41:12,079 --> 00:41:08,430 things that we should start thinking 1007 00:41:16,420 --> 00:41:12,089 about now because we are rapidly 1008 00:41:19,070 --> 00:41:16,430 outpacing our treaties and existing laws 1009 00:41:20,660 --> 00:41:19,080 just again to show that the ethic still 1010 00:41:23,359 --> 00:41:20,670 has a ways to go to catch up with the 1011 00:41:25,910 --> 00:41:23,369 engineering of settlement yeah the next 1012 00:41:28,970 --> 00:41:25,920 question is by Andrew Planet who asks on 1013 00:41:32,660 --> 00:41:28,980 Twitter is space exploit is the language 1014 00:41:34,760 --> 00:41:32,670 of space exploration biased to our still 1015 00:41:37,430 --> 00:41:34,770 earthbound existence or will it change 1016 00:41:41,570 --> 00:41:37,440 once we settle a long term beyond our 1017 00:41:44,050 --> 00:41:41,580 planet that's an interesting question I 1018 00:41:48,290 --> 00:41:44,060 am not totally sure I understand it I 1019 00:41:50,420 --> 00:41:48,300 think I think that it's very much biased 1020 00:41:53,329 --> 00:41:50,430 towards earthbound existence at the 1021 00:41:57,800 --> 00:41:53,339 moment in part because like that's where 1022 00:42:00,650 --> 00:41:57,810 we live you know so I think if you're 1023 00:42:02,900 --> 00:42:00,660 asking about like Earth's history then 1024 00:42:06,349 --> 00:42:02,910 for sure you know like we draw on 1025 00:42:07,910 --> 00:42:06,359 Earth's history in part because you know 1026 00:42:10,970 --> 00:42:07,920 like it's the history that we're 1027 00:42:13,339 --> 00:42:10,980 familiar with as I said earlier in the 1028 00:42:15,770 --> 00:42:13,349 program you know I think the histories 1029 00:42:17,120 --> 00:42:15,780 that we tend to draw from where I'm 1030 00:42:19,609 --> 00:42:17,130 using weed to me and Astra 1031 00:42:22,339 --> 00:42:19,619 just also reflect the lack of diversity 1032 00:42:23,870 --> 00:42:22,349 in the field in that you know people 1033 00:42:27,230 --> 00:42:23,880 tend to draw on European history 1034 00:42:29,240 --> 00:42:27,240 particularly that's why you see you know 1035 00:42:31,099 --> 00:42:29,250 these examples of like European 1036 00:42:33,440 --> 00:42:31,109 colonization of the Americas pop up 1037 00:42:35,269 --> 00:42:33,450 again and again whereas there are there 1038 00:42:37,309 --> 00:42:35,279 are a lot of examples of people leaving 1039 00:42:38,990 --> 00:42:37,319 their home territories and exploring 1040 00:42:42,950 --> 00:42:39,000 other areas that aren't necessarily 1041 00:42:45,620 --> 00:42:42,960 those so you know I think we tend to 1042 00:42:47,779 --> 00:42:45,630 always draw on examples that we're 1043 00:42:49,999 --> 00:42:47,789 familiar with whether that is drawn from 1044 00:42:51,620 --> 00:42:50,009 a particular earth culture or whether 1045 00:42:53,839 --> 00:42:51,630 it's drawn from the history of the 1046 00:42:56,269 --> 00:42:53,849 entire earth itself you know as long as 1047 00:42:58,700 --> 00:42:56,279 we are you know terrestrial beings 1048 00:43:00,470 --> 00:42:58,710 I think that'll probably continue to be 1049 00:43:02,210 --> 00:43:00,480 the case but you know who knows what's 1050 00:43:04,759 --> 00:43:02,220 possible I I personally have been 1051 00:43:08,180 --> 00:43:04,769 recently watching the expanse and I've 1052 00:43:10,609 --> 00:43:08,190 been really interested to see how things 1053 00:43:11,630 --> 00:43:10,619 are framed in this sort of those who 1054 00:43:12,589 --> 00:43:11,640 haven't watched it without giving 1055 00:43:14,299 --> 00:43:12,599 anything away 1056 00:43:17,120 --> 00:43:14,309 you know it's world in which people live 1057 00:43:18,559 --> 00:43:17,130 the asteroid belt Earth and Mars and 1058 00:43:20,900 --> 00:43:18,569 there's all these like you know 1059 00:43:23,269 --> 00:43:20,910 conflicts and competition between these 1060 00:43:25,670 --> 00:43:23,279 three groups of folks having these 1061 00:43:28,370 --> 00:43:25,680 different like physical locations within 1062 00:43:30,589 --> 00:43:28,380 the system and the cultural identities 1063 00:43:33,740 --> 00:43:30,599 that come from those so that's been 1064 00:43:36,680 --> 00:43:33,750 really fun to see it sounds like an 1065 00:43:38,390 --> 00:43:36,690 awesome talking about diversity the next 1066 00:43:41,390 --> 00:43:38,400 question is by Rashmi 1067 00:43:43,099 --> 00:43:41,400 Shiv nee who asks on Twitter miss fields 1068 00:43:44,990 --> 00:43:43,109 astrobiology is so welcoming of many 1069 00:43:46,789 --> 00:43:45,000 people with diverse backgrounds Thank 1070 00:43:49,519 --> 00:43:46,799 You ash me I think so too we could do 1071 00:43:51,349 --> 00:43:49,529 better across multiple fields and are 1072 00:43:53,630 --> 00:43:51,359 there any other disciplines you hope 1073 00:43:55,160 --> 00:43:53,640 will jump on board in the effort to 1074 00:43:58,880 --> 00:43:55,170 search for life in the universe ie 1075 00:44:00,230 --> 00:43:58,890 linguists artists and so on yeah you 1076 00:44:02,269 --> 00:44:00,240 know one of the things that I think is 1077 00:44:04,279 --> 00:44:02,279 really interesting about astrobiology is 1078 00:44:07,940 --> 00:44:04,289 you know the we do talk a lot about like 1079 00:44:10,460 --> 00:44:07,950 the mix of fields in the sciences that 1080 00:44:13,009 --> 00:44:10,470 are in like the physical sciences that 1081 00:44:14,569 --> 00:44:13,019 are within the field but also like 1082 00:44:17,240 --> 00:44:14,579 astrobiology has a long history of 1083 00:44:21,069 --> 00:44:17,250 engagement with sociologists Ephesus 1084 00:44:24,319 --> 00:44:21,079 artists linguists as well and I think 1085 00:44:26,539 --> 00:44:24,329 you know just recently I so viewers may 1086 00:44:28,279 --> 00:44:26,549 or may not be aware that astronomy as a 1087 00:44:30,350 --> 00:44:28,289 field has very interesting practice 1088 00:44:32,590 --> 00:44:30,360 called the decadal survey 1089 00:44:35,720 --> 00:44:32,600 we're like every 10 years astronomers 1090 00:44:38,240 --> 00:44:35,730 from like all over the US get together 1091 00:44:41,060 --> 00:44:38,250 and you know in many cases like all over 1092 00:44:42,980 --> 00:44:41,070 the world get together and write these 1093 00:44:44,540 --> 00:44:42,990 papers about what they think the high 1094 00:44:46,640 --> 00:44:44,550 priorities should be for like the next 1095 00:44:49,970 --> 00:44:46,650 decade so it's sort of like this whole 1096 00:44:52,010 --> 00:44:49,980 community-wide vision setting exercise 1097 00:44:54,650 --> 00:44:52,020 though that we lots of us participate 1098 00:44:56,420 --> 00:44:54,660 it's all totally voluntary this 1099 00:44:58,370 --> 00:44:56,430 eventually ends up in like a big report 1100 00:45:00,740 --> 00:44:58,380 that helps guide decisions about like 1101 00:45:02,360 --> 00:45:00,750 funding going forward and I've been very 1102 00:45:04,610 --> 00:45:02,370 happy to see that in this decade all 1103 00:45:07,280 --> 00:45:04,620 survey there have been papers about the 1104 00:45:09,830 --> 00:45:07,290 importance of interdisciplinarity to 1105 00:45:12,980 --> 00:45:09,840 astrobiology and also specifically in 1106 00:45:14,930 --> 00:45:12,990 the context of SETI searches as well so 1107 00:45:16,430 --> 00:45:14,940 understanding you know like not only how 1108 00:45:18,800 --> 00:45:16,440 to guide our searches but also what the 1109 00:45:21,170 --> 00:45:18,810 implications of like contact with 1110 00:45:23,780 --> 00:45:21,180 another species from off of this world 1111 00:45:26,150 --> 00:45:23,790 might actually be so you know I think 1112 00:45:28,400 --> 00:45:26,160 that I this has been one of the areas in 1113 00:45:30,320 --> 00:45:28,410 which astrobiology is very 1114 00:45:32,930 --> 00:45:30,330 forward-thinking I think it could always 1115 00:45:36,080 --> 00:45:32,940 do well to interface more with the 1116 00:45:38,120 --> 00:45:36,090 humanities you know and again the more 1117 00:45:39,830 --> 00:45:38,130 like the more voices in the conversation 1118 00:45:42,890 --> 00:45:39,840 I think often the richer the 1119 00:45:44,600 --> 00:45:42,900 conversation but I think that it's it's 1120 00:45:46,220 --> 00:45:44,610 even broader than you think it is and 1121 00:45:48,770 --> 00:45:46,230 getting more so all the time and that's 1122 00:45:51,080 --> 00:45:48,780 really great I would love to see more 1123 00:45:53,570 --> 00:45:51,090 humanitarian more sessions at apps icon 1124 00:45:56,420 --> 00:45:53,580 on the humanities of astrobiology w 1125 00:45:59,360 --> 00:45:56,430 really fascinating the next question is 1126 00:46:02,030 --> 00:45:59,370 by Laura from Twitter who asks as a 1127 00:46:04,220 --> 00:46:02,040 Columbian I love the way how Shaka Lulu 1128 00:46:06,470 --> 00:46:04,230 described the similarities between space 1129 00:46:08,480 --> 00:46:06,480 settlement and colonization there should 1130 00:46:09,260 --> 00:46:08,490 be more talk about inclusion related to 1131 00:46:11,360 --> 00:46:09,270 space exploration 1132 00:46:13,580 --> 00:46:11,370 are there any authors or texts you would 1133 00:46:15,730 --> 00:46:13,590 recommend to read more about these views 1134 00:46:19,940 --> 00:46:15,740 oh goodness 1135 00:46:22,280 --> 00:46:19,950 yeah so there's it depends where you 1136 00:46:26,240 --> 00:46:22,290 want to start so I think there's been 1137 00:46:29,450 --> 00:46:26,250 quite a lot of really good just popular 1138 00:46:33,650 --> 00:46:29,460 articles in the in the press recently so 1139 00:46:34,820 --> 00:46:33,660 certainly a lot of like for example in 1140 00:46:37,460 --> 00:46:34,830 the past year 1141 00:46:39,770 --> 00:46:37,470 Gizmodo and Newsweek have both an NGO 1142 00:46:43,370 --> 00:46:39,780 have all written about some of the 1143 00:46:45,230 --> 00:46:43,380 conversations that are ongoing about the 1144 00:46:47,330 --> 00:46:45,240 language that we use around space 1145 00:46:49,580 --> 00:46:47,340 exploration and those are good places to 1146 00:46:52,160 --> 00:46:49,590 start one of the people that I have 1147 00:46:53,900 --> 00:46:52,170 really learned a lot from from is Shonda 1148 00:46:55,730 --> 00:46:53,910 prescott weinstein who's a theoretical 1149 00:46:58,310 --> 00:46:55,740 astrophysicist at the university of new 1150 00:47:00,410 --> 00:46:58,320 hampshire Shonda maintains a 1151 00:47:03,110 --> 00:47:00,420 decolonizing science reading list that 1152 00:47:04,970 --> 00:47:03,120 is not specifically focused necessarily 1153 00:47:07,760 --> 00:47:04,980 on space exploration but I think is a 1154 00:47:10,900 --> 00:47:07,770 really strong place to start 1155 00:47:16,160 --> 00:47:10,910 you know I think particularly a lot of 1156 00:47:19,160 --> 00:47:16,170 rethinking how how we frame and and 1157 00:47:21,320 --> 00:47:19,170 actually conduct this kind of like 1158 00:47:24,590 --> 00:47:21,330 scientific enterprise that we're all 1159 00:47:27,050 --> 00:47:24,600 engaged in you know a lot of the reading 1160 00:47:30,080 --> 00:47:27,060 is not necessarily even specific to 1161 00:47:31,790 --> 00:47:30,090 space it's really understanding the 1162 00:47:35,270 --> 00:47:31,800 history of science and the ways in which 1163 00:47:37,790 --> 00:47:35,280 like science has has functioned within 1164 00:47:39,890 --> 00:47:37,800 these larger colonial structures because 1165 00:47:41,360 --> 00:47:39,900 I think a lot of times you know even we 1166 00:47:43,880 --> 00:47:41,370 scientists and I'm sure that I do this 1167 00:47:46,760 --> 00:47:43,890 as well have a way of like posing like 1168 00:47:48,920 --> 00:47:46,770 science as this kind of like completely 1169 00:47:52,160 --> 00:47:48,930 value neutral thing which it has 1170 00:47:54,140 --> 00:47:52,170 historically not been at all so I you 1171 00:47:56,990 --> 00:47:54,150 know I would certainly recommend reading 1172 00:47:59,570 --> 00:47:57,000 some of the articles you can find them 1173 00:48:02,030 --> 00:47:59,580 as many of them linked actually from my 1174 00:48:04,370 --> 00:48:02,040 website tangled fields com 1175 00:48:06,590 --> 00:48:04,380 but you you should start there but then 1176 00:48:07,400 --> 00:48:06,600 I would also check out dr. Prescott 1177 00:48:09,920 --> 00:48:07,410 Weinstein's 1178 00:48:11,360 --> 00:48:09,930 decolonizing science reading list for 1179 00:48:15,200 --> 00:48:11,370 some other really excellent places to 1180 00:48:18,230 --> 00:48:15,210 start thank you the next question is by 1181 00:48:21,020 --> 00:48:18,240 Genova and Barassi on cygnets who asks 1182 00:48:26,480 --> 00:48:21,030 is habitability ever changing in our own 1183 00:48:28,850 --> 00:48:26,490 solar system oh yes so you know one of 1184 00:48:33,380 --> 00:48:28,860 the one of the things that i think is so 1185 00:48:35,390 --> 00:48:33,390 fascinating about Mars in particular but 1186 00:48:38,420 --> 00:48:35,400 I often like thinking about like Mars 1187 00:48:40,010 --> 00:48:38,430 Venus on earth as sort of like you know 1188 00:48:41,900 --> 00:48:40,020 in a in a Christmas Carol there's like 1189 00:48:44,300 --> 00:48:41,910 the ghost of Christmas past in future 1190 00:48:46,670 --> 00:48:44,310 and the ghost of Christmas present and 1191 00:48:49,760 --> 00:48:46,680 you know they're all like different 1192 00:48:53,210 --> 00:48:49,770 possible outcomes of you know the same 1193 00:48:55,130 --> 00:48:53,220 Syrian series of events right so I when 1194 00:48:55,630 --> 00:48:55,140 we look at Mars for example one of the 1195 00:48:57,280 --> 00:48:55,640 reasons 1196 00:48:59,890 --> 00:48:57,290 that Mars is such an interesting place 1197 00:49:02,350 --> 00:48:59,900 to study is that it's a world where we 1198 00:49:03,870 --> 00:49:02,360 have pretty good evidence now it was a 1199 00:49:06,250 --> 00:49:03,880 much more hospitable environment 1200 00:49:08,770 --> 00:49:06,260 potentially for life in the past than it 1201 00:49:11,380 --> 00:49:08,780 is today and you know the reasons for 1202 00:49:13,870 --> 00:49:11,390 that are many one of the primary reasons 1203 00:49:16,510 --> 00:49:13,880 is that you know Mars no longer really 1204 00:49:19,060 --> 00:49:16,520 has a robust emmonak magnetic field and 1205 00:49:21,370 --> 00:49:19,070 that its atmosphere has changed a lot 1206 00:49:23,770 --> 00:49:21,380 over time so you know we now know that 1207 00:49:26,080 --> 00:49:23,780 there was at some point like standing 1208 00:49:29,050 --> 00:49:26,090 water on the surface of Mars and lots of 1209 00:49:31,750 --> 00:49:29,060 it for a long amount of time but today 1210 00:49:34,690 --> 00:49:31,760 the atmosphere is very thin extremely 1211 00:49:36,310 --> 00:49:34,700 dry you know largely carbon dioxide 1212 00:49:40,000 --> 00:49:36,320 there's not really like a whole lot of 1213 00:49:42,940 --> 00:49:40,010 like chemical cycling happening on the 1214 00:49:44,290 --> 00:49:42,950 on the planet there's like leftover 1215 00:49:46,270 --> 00:49:44,300 magnetic fields but not a lot of 1216 00:49:49,150 --> 00:49:46,280 shielding from the radiation from the 1217 00:49:51,820 --> 00:49:49,160 Sun and so by studying Mars we can look 1218 00:49:54,190 --> 00:49:51,830 at an environment that we see today as 1219 00:49:56,470 --> 00:49:54,200 being not what we would think of as 1220 00:49:59,380 --> 00:49:56,480 traditionally habitable and not even 1221 00:50:02,290 --> 00:49:59,390 particularly hospitable at all but we 1222 00:50:05,530 --> 00:50:02,300 can study its past and learn about how 1223 00:50:08,470 --> 00:50:05,540 the how this world at least in Mars case 1224 00:50:11,920 --> 00:50:08,480 might have lost its habitability you 1225 00:50:14,200 --> 00:50:11,930 know when we look at our own planets you 1226 00:50:17,290 --> 00:50:14,210 know we see the changes that are 1227 00:50:19,840 --> 00:50:17,300 happening in our climate and one of the 1228 00:50:22,570 --> 00:50:19,850 worries for us right is that we might 1229 00:50:25,570 --> 00:50:22,580 lose our habitability you know the 1230 00:50:27,310 --> 00:50:25,580 planet will still be there like if you 1231 00:50:29,830 --> 00:50:27,320 look at Venus Venus is trucking along 1232 00:50:33,070 --> 00:50:29,840 just fine but there's a reason that you 1233 00:50:35,440 --> 00:50:33,080 don't hear about Venus rovers and that's 1234 00:50:38,140 --> 00:50:35,450 because Venus is you know very very very 1235 00:50:40,060 --> 00:50:38,150 very very hot not very hospitable 1236 00:50:41,590 --> 00:50:40,070 environment for totally different 1237 00:50:43,780 --> 00:50:41,600 reasons than Mars is an inhospitable 1238 00:50:46,360 --> 00:50:43,790 environment right so we have this 1239 00:50:48,940 --> 00:50:46,370 wonderful diversity of worlds within our 1240 00:50:50,920 --> 00:50:48,950 own solar system including our own that 1241 00:50:54,010 --> 00:50:50,930 I think can really help us understand 1242 00:50:55,200 --> 00:50:54,020 you know not only what it means to be a 1243 00:50:57,790 --> 00:50:55,210 planet that is 1244 00:51:01,240 --> 00:50:57,800 hospitable to life and actually has life 1245 00:51:03,880 --> 00:51:01,250 but also what possible pathways forward 1246 00:51:06,760 --> 00:51:03,890 might cause you know like us or other 1247 00:51:07,770 --> 00:51:06,770 worlds to lose that that habitability 1248 00:51:10,560 --> 00:51:07,780 and 1249 00:51:12,330 --> 00:51:10,570 you know I think habitability is is very 1250 00:51:14,220 --> 00:51:12,340 much you know we often talk about it as 1251 00:51:16,140 --> 00:51:14,230 just like how far is a planet from the 1252 00:51:18,780 --> 00:51:16,150 Sun but it has all of these 1253 00:51:22,230 --> 00:51:18,790 complications and wonderful details that 1254 00:51:25,740 --> 00:51:22,240 make it a very shifting and evolving 1255 00:51:27,150 --> 00:51:25,750 thing with time yeah I think that's one 1256 00:51:29,330 --> 00:51:27,160 of the beauties of astrobiology is that 1257 00:51:32,310 --> 00:51:29,340 it brings you a new sense of 1258 00:51:34,710 --> 00:51:32,320 appreciation and wonder of our own world 1259 00:51:36,420 --> 00:51:34,720 seen from far away appreciate of the 1260 00:51:38,760 --> 00:51:36,430 evolution of Earth through time how has 1261 00:51:40,200 --> 00:51:38,770 this changed or the impacts of human and 1262 00:51:42,540 --> 00:51:40,210 how does that reflect in other worlds in 1263 00:51:44,339 --> 00:51:42,550 our solar system makes you much more 1264 00:51:46,970 --> 00:51:44,349 appreciative about what we have on our 1265 00:51:49,980 --> 00:51:46,980 own planet yeah absolutely 1266 00:51:53,849 --> 00:51:49,990 the next question is from Graham Lau my 1267 00:51:56,040 --> 00:51:53,859 fiercely bearded co-host he asks can you 1268 00:51:58,020 --> 00:51:56,050 name a piece of art writing film or 1269 00:52:05,720 --> 00:51:58,030 other media that most inspired you to 1270 00:52:12,990 --> 00:52:09,900 you know I actually think it might be so 1271 00:52:15,839 --> 00:52:13,000 I I will caveat this with the fact that 1272 00:52:17,640 --> 00:52:15,849 like I read like you know old science 1273 00:52:19,710 --> 00:52:17,650 fiction like Ray Bradbury story is when 1274 00:52:22,500 --> 00:52:19,720 I was like in junior high but I'm not 1275 00:52:24,300 --> 00:52:22,510 generally like a great consumer of like 1276 00:52:27,180 --> 00:52:24,310 science fiction specifically which is 1277 00:52:28,829 --> 00:52:27,190 usually what people are asking about you 1278 00:52:31,500 --> 00:52:28,839 know as far as like being inspired to 1279 00:52:34,859 --> 00:52:31,510 study astrobiology or science more 1280 00:52:36,900 --> 00:52:34,869 broadly I actually have a answer to this 1281 00:52:39,630 --> 00:52:36,910 that I think is fairly unusual which is 1282 00:52:41,849 --> 00:52:39,640 that I read a book by a woman named 1283 00:52:45,540 --> 00:52:41,859 Donna Shirley called managing Martians 1284 00:52:49,980 --> 00:52:45,550 that so she was the I believe project 1285 00:52:52,710 --> 00:52:49,990 manager for the surgery rover and it was 1286 00:52:54,720 --> 00:52:52,720 about her career so that would have come 1287 00:52:56,160 --> 00:52:54,730 out you know in the late 90s or 1288 00:52:58,410 --> 00:52:56,170 something so it must have been like 1289 00:53:00,530 --> 00:52:58,420 right within my last year of high school 1290 00:53:02,970 --> 00:53:00,540 or first year of college that I read it 1291 00:53:06,240 --> 00:53:02,980 but it was a very fascinating book 1292 00:53:08,310 --> 00:53:06,250 because it was about her career and you 1293 00:53:10,200 --> 00:53:08,320 know her being like the generation 1294 00:53:13,349 --> 00:53:10,210 before me as like a woman in science and 1295 00:53:15,990 --> 00:53:13,359 engineering she you know really didn't 1296 00:53:18,150 --> 00:53:16,000 have a ton of opportunities in in many 1297 00:53:19,680 --> 00:53:18,160 ways the beginning of her career was not 1298 00:53:20,960 --> 00:53:19,690 very illustrious she had like a really 1299 00:53:23,450 --> 00:53:20,970 hard time and I think 1300 00:53:25,820 --> 00:53:23,460 actually ended up if I remember 1301 00:53:27,080 --> 00:53:25,830 correctly and it's been a long time but 1302 00:53:30,230 --> 00:53:27,090 if I remember correctly she actually 1303 00:53:33,290 --> 00:53:30,240 ended up working at NASA after just 1304 00:53:36,770 --> 00:53:33,300 working as like a drafts person for an 1305 00:53:39,109 --> 00:53:36,780 engineering company and gradually ended 1306 00:53:42,170 --> 00:53:39,119 up managing this incredible like the 1307 00:53:45,800 --> 00:53:42,180 first Mars rover mission and I think 1308 00:53:49,280 --> 00:53:45,810 that kind of gave me some early exposure 1309 00:53:51,830 --> 00:53:49,290 to the sort of what I would call like 1310 00:53:53,420 --> 00:53:51,840 the project aspect of science so you 1311 00:53:55,160 --> 00:53:53,430 know like we think about like scientists 1312 00:53:56,540 --> 00:53:55,170 doing their work but then you know these 1313 00:54:00,170 --> 00:53:56,550 missions that we talk about like Kepler 1314 00:54:01,790 --> 00:54:00,180 are these huge collaborations of people 1315 00:54:04,609 --> 00:54:01,800 that have like very specific knowledge 1316 00:54:06,290 --> 00:54:04,619 that combine it all to create this like 1317 00:54:08,120 --> 00:54:06,300 piece of technology that then is like 1318 00:54:10,160 --> 00:54:08,130 able to answer all these science 1319 00:54:12,530 --> 00:54:10,170 questions it's really like as far as 1320 00:54:15,560 --> 00:54:12,540 like the human side of it it's a very 1321 00:54:17,810 --> 00:54:15,570 interesting thing to me and I've always 1322 00:54:19,550 --> 00:54:17,820 found like the ways in which scientists 1323 00:54:22,550 --> 00:54:19,560 do their work and like the ways in which 1324 00:54:25,520 --> 00:54:22,560 we organize ourselves and the the myriad 1325 00:54:28,460 --> 00:54:25,530 skills beyond just being good like math 1326 00:54:30,710 --> 00:54:28,470 or lab science you know your ability to 1327 00:54:33,589 --> 00:54:30,720 like keep up on your email and like 1328 00:54:34,880 --> 00:54:33,599 manage your time and write things you 1329 00:54:37,310 --> 00:54:34,890 know all these things that people don't 1330 00:54:39,770 --> 00:54:37,320 think of as being specific science 1331 00:54:41,720 --> 00:54:39,780 skills but that really are I think that 1332 00:54:43,250 --> 00:54:41,730 was one of the things that I found 1333 00:54:46,089 --> 00:54:43,260 really interesting about that book that 1334 00:54:48,230 --> 00:54:46,099 I had this interaction with early on 1335 00:54:50,500 --> 00:54:48,240 cool thank you thank you for that I have 1336 00:54:54,079 --> 00:54:50,510 to read that the next question is by 1337 00:54:56,690 --> 00:54:54,089 Ashish Nath who asks on Twitter is 1338 00:54:59,000 --> 00:54:56,700 interpolated is interplanetary 1339 00:55:05,900 --> 00:54:59,010 colonization really in need of this hour 1340 00:55:08,120 --> 00:55:05,910 or not so I would say not you know I 1341 00:55:10,970 --> 00:55:08,130 think a lot of times and you touched on 1342 00:55:14,390 --> 00:55:10,980 this century a little while ago I the 1343 00:55:17,660 --> 00:55:14,400 kind of urgency that is often posed 1344 00:55:21,740 --> 00:55:17,670 behind you know humans like needing to 1345 00:55:25,490 --> 00:55:21,750 go and live off of offworld is to me 1346 00:55:27,920 --> 00:55:25,500 often largely artificially induced you 1347 00:55:29,990 --> 00:55:27,930 know I think we do have like urgent 1348 00:55:32,630 --> 00:55:30,000 issues and challenges in living on our 1349 00:55:34,220 --> 00:55:32,640 world but none of them are really 1350 00:55:38,420 --> 00:55:34,230 directly address 1351 00:55:39,800 --> 00:55:38,430 by going and sending humans to live on 1352 00:55:43,760 --> 00:55:39,810 another world in which their resources 1353 00:55:46,310 --> 00:55:43,770 are not met you know I think that space 1354 00:55:47,930 --> 00:55:46,320 exploration and you know like you 1355 00:55:50,270 --> 00:55:47,940 specifically like the challenges of 1356 00:55:52,820 --> 00:55:50,280 sending humans into space offers us many 1357 00:55:55,460 --> 00:55:52,830 scientific opportunities it offers us 1358 00:55:57,260 --> 00:55:55,470 opportunities to learn about living in 1359 00:55:59,510 --> 00:55:57,270 inhospitable environments that could be 1360 00:56:02,890 --> 00:55:59,520 very helpful for our understanding of 1361 00:56:06,260 --> 00:56:02,900 how we might live as our earth changes 1362 00:56:09,590 --> 00:56:06,270 you know I think that a lot of times 1363 00:56:11,630 --> 00:56:09,600 though the kind of urgency you know even 1364 00:56:13,790 --> 00:56:11,640 for example when you look at like we're 1365 00:56:16,280 --> 00:56:13,800 going to put people on them the most 1366 00:56:20,230 --> 00:56:16,290 recent like NASA effort of we're going 1367 00:56:26,090 --> 00:56:22,460 there's no reason the moon's going to be 1368 00:56:29,180 --> 00:56:26,100 there in 2025 you know a lot of these 1369 00:56:32,150 --> 00:56:29,190 things are driven out of either politics 1370 00:56:33,590 --> 00:56:32,160 or eco you know a lot of times when 1371 00:56:35,270 --> 00:56:33,600 people are like we have to do it now 1372 00:56:38,450 --> 00:56:35,280 what they really mean is like I want to 1373 00:56:40,640 --> 00:56:38,460 do it to do it my lifetime and I I 1374 00:56:43,460 --> 00:56:40,650 totally understand that you know like I 1375 00:56:48,020 --> 00:56:43,470 understand that like human need like I 1376 00:56:50,210 --> 00:56:48,030 am I am constantly berating myself that 1377 00:56:53,720 --> 00:56:50,220 like everything takes about like five to 1378 00:56:54,980 --> 00:56:53,730 10 times longer than I wish it did you 1379 00:56:56,450 --> 00:56:54,990 know and so I'm constantly very 1380 00:56:58,790 --> 00:56:56,460 impatient but I always have to remind 1381 00:57:02,030 --> 00:56:58,800 myself that that impatience like comes 1382 00:57:03,800 --> 00:57:02,040 from me and so I think you know when we 1383 00:57:05,240 --> 00:57:03,810 look at the the scope of the things that 1384 00:57:08,000 --> 00:57:05,250 we're trying to do and the challenges 1385 00:57:11,510 --> 00:57:08,010 that we have that we you know we don't 1386 00:57:14,150 --> 00:57:11,520 have to do it tomorrow and you know I 1387 00:57:16,190 --> 00:57:14,160 think it's worth thinking about how we 1388 00:57:18,340 --> 00:57:16,200 would want to do it and maybe taking our 1389 00:57:20,870 --> 00:57:18,350 ego a little bit out of the equation 1390 00:57:24,740 --> 00:57:20,880 when we think about what that timescale 1391 00:57:26,359 --> 00:57:24,750 should really be oh yeah um so we're 1392 00:57:28,910 --> 00:57:26,369 running you're low on time so we'll have 1393 00:57:31,670 --> 00:57:28,920 one more question and that is by M Flynn 1394 00:57:33,710 --> 00:57:31,680 who acts on Twitter what advice do you 1395 00:57:35,240 --> 00:57:33,720 have for a college-bound person who is 1396 00:57:37,490 --> 00:57:35,250 interested in both a scientific field 1397 00:57:39,740 --> 00:57:37,500 like astronomy biology or physics as 1398 00:57:42,920 --> 00:57:39,750 well as the arts what's the best way to 1399 00:57:44,630 --> 00:57:42,930 find a balance between the two yeah 1400 00:57:46,570 --> 00:57:44,640 that's a great question it's one that I 1401 00:57:51,100 --> 00:57:46,580 have definitely had 1402 00:57:53,020 --> 00:57:51,110 address myself you know i so i majored 1403 00:57:54,430 --> 00:57:53,030 in physics i originally actually was 1404 00:57:56,440 --> 00:57:54,440 planning to major in chemistry and 1405 00:57:58,420 --> 00:57:56,450 physics double and then I realized that 1406 00:58:00,390 --> 00:57:58,430 also I needed to eat and sleep during 1407 00:58:03,850 --> 00:58:00,400 the course of you know individual days 1408 00:58:05,590 --> 00:58:03,860 so I ended up just majoring in physics 1409 00:58:07,510 --> 00:58:05,600 and I've always had a like a 1410 00:58:09,520 --> 00:58:07,520 long-standing interest in art and so a 1411 00:58:12,250 --> 00:58:09,530 lot of my for example in college a lot 1412 00:58:13,810 --> 00:58:12,260 of my electives were in painting which 1413 00:58:15,940 --> 00:58:13,820 was the primary art that I was 1414 00:58:18,580 --> 00:58:15,950 practicing during that time you know but 1415 00:58:21,390 --> 00:58:18,590 I would say that because there are a 1416 00:58:24,550 --> 00:58:21,400 limited number of hours in the day that 1417 00:58:26,740 --> 00:58:24,560 making sure to prioritize maintaining an 1418 00:58:28,630 --> 00:58:26,750 artistic practice in whatever way you 1419 00:58:30,730 --> 00:58:28,640 know feels good and important to you 1420 00:58:32,650 --> 00:58:30,740 whether it's you know like it could be 1421 00:58:34,630 --> 00:58:32,660 dance or performance it could be music 1422 00:58:38,590 --> 00:58:34,640 it could be visual art whatever it 1423 00:58:41,230 --> 00:58:38,600 happens to be that maintaining that that 1424 00:58:43,120 --> 00:58:41,240 priority being important to you makes it 1425 00:58:45,640 --> 00:58:43,130 worth making time for but also 1426 00:58:48,700 --> 00:58:45,650 understanding that time management is 1427 00:58:52,900 --> 00:58:48,710 always breathable so you know when I was 1428 00:58:54,730 --> 00:58:52,910 in grad school I actually like was kind 1429 00:58:56,410 --> 00:58:54,740 of midway through grad school was 1430 00:58:58,000 --> 00:58:56,420 approached for I was drawing comics at 1431 00:59:00,370 --> 00:58:58,010 the time and I was like approached for a 1432 00:59:02,650 --> 00:59:00,380 couple potential publishing gigs 1433 00:59:04,570 --> 00:59:02,660 none of which actually panned out which 1434 00:59:06,700 --> 00:59:04,580 in retrospect like I don't know how I 1435 00:59:10,810 --> 00:59:06,710 was thinking I would be in grad school 1436 00:59:12,700 --> 00:59:10,820 and like write a comic full-time also so 1437 00:59:15,670 --> 00:59:12,710 you know like and then when that didn't 1438 00:59:17,170 --> 00:59:15,680 pan out I ended up like redoubling my 1439 00:59:19,210 --> 00:59:17,180 efforts and like having to write my 1440 00:59:20,620 --> 00:59:19,220 thesis and stuff which was completely 1441 00:59:22,810 --> 00:59:20,630 consuming and there were a couple of 1442 00:59:24,640 --> 00:59:22,820 years where I just like wasn't really I 1443 00:59:27,760 --> 00:59:24,650 didn't have any time to do things like 1444 00:59:29,350 --> 00:59:27,770 play music or make art and that didn't 1445 00:59:32,410 --> 00:59:29,360 mean that I like would never do them 1446 00:59:35,140 --> 00:59:32,420 again you know like now I have a much 1447 00:59:37,720 --> 00:59:35,150 more like balanced ability to like 1448 00:59:39,280 --> 00:59:37,730 manage those things in my life but it's 1449 00:59:40,570 --> 00:59:39,290 it has to be flexible you know like 1450 00:59:43,120 --> 00:59:40,580 sometimes you're not going to be able to 1451 00:59:45,070 --> 00:59:43,130 do both you know but as long as you're 1452 00:59:46,780 --> 00:59:45,080 constantly trying to kind of keep it on 1453 00:59:50,200 --> 00:59:46,790 an even keel you'll probably get some 1454 00:59:51,610 --> 00:59:50,210 mix that is satisfying for you wonderful 1455 00:59:53,470 --> 00:59:51,620 wonderful that's a great advice to see 1456 00:59:58,170 --> 00:59:53,480 and you have some perhaps final words of 1457 01:00:02,499 --> 01:00:00,039 don't know stick with 1458 01:00:05,439 --> 01:00:02,509 whatever you're interested in don't let 1459 01:00:08,829 --> 01:00:05,449 anybody pigeonhole you Interdisciplinary 1460 01:00:11,620 --> 01:00:08,839 is great we always end our show as our 1461 01:00:13,509
