1 00:00:17,810 --> 00:00:15,709 for hundreds of years thousands of years 2 00:00:20,870 --> 00:00:17,820 humans have thought the universe is a 3 00:00:22,730 --> 00:00:20,880 very static place figure out at night 4 00:00:25,490 --> 00:00:22,740 and look into the night sky you will see 5 00:00:27,830 --> 00:00:25,500 that things don't really change much the 6 00:00:30,530 --> 00:00:27,840 universe appeared very static for a long 7 00:00:32,840 --> 00:00:30,540 time we now know this is not true the 8 00:00:35,630 --> 00:00:32,850 universe is a highly dynamic place and 9 00:00:38,390 --> 00:00:35,640 things are happening all the time every 10 00:00:40,400 --> 00:00:38,400 single second a star explodes in a 11 00:00:42,230 --> 00:00:40,410 gigantic supernova explosion somewhere 12 00:00:43,910 --> 00:00:42,240 in the universe and they have to go and 13 00:00:45,680 --> 00:00:43,920 find it we have to build instruments 14 00:00:51,500 --> 00:00:45,690 that are capable of finding those 15 00:00:53,360 --> 00:00:51,510 unforeseen events way back in 1998 we 16 00:00:57,950 --> 00:00:53,370 were at a scientific meeting in Boulder 17 00:01:00,830 --> 00:00:57,960 Colorado and I was invited to invite a 18 00:01:02,870 --> 00:01:00,840 you know invitation only meeting and at 19 00:01:04,280 --> 00:01:02,880 that meeting six of us got together and 20 00:01:06,020 --> 00:01:04,290 we came up with the idea of creating 21 00:01:10,520 --> 00:01:06,030 Swift it was a group of people from 22 00:01:13,790 --> 00:01:10,530 Goddard and from Penn State Swift set 23 00:01:18,469 --> 00:01:13,800 out to combine gamma-ray instruments 24 00:01:20,840 --> 00:01:18,479 that could roughly find out where the 25 00:01:24,100 --> 00:01:20,850 gamma rays may be coming from but only 26 00:01:27,170 --> 00:01:24,110 with a very crude estimate and then 27 00:01:29,840 --> 00:01:27,180 through the design of this remarkable 28 00:01:33,950 --> 00:01:29,850 spacecraft to spin that spacecraft 29 00:01:35,990 --> 00:01:33,960 rapidly across the sky and point an 30 00:01:39,109 --> 00:01:36,000 x-ray telescope and an optical 31 00:01:41,740 --> 00:01:39,119 ultraviolet telescope at the possible 32 00:01:43,940 --> 00:01:41,750 location of the gamma ray burst 33 00:01:46,190 --> 00:01:43,950 whenever a gamma-ray burst goes off 34 00:01:47,990 --> 00:01:46,200 which happens about twice a week the 35 00:01:49,969 --> 00:01:48,000 satellite detects the gamma ray burst 36 00:01:52,700 --> 00:01:49,979 and it sends a message down to the 37 00:01:55,160 --> 00:01:52,710 ground and it goes out on a network to 38 00:01:58,460 --> 00:01:55,170 our cellphones and were paged what I 39 00:02:00,620 --> 00:01:58,470 love being a member of 50ms is carrying 40 00:02:03,590 --> 00:02:00,630 a blackberry on the side of my hip that 41 00:02:05,749 --> 00:02:03,600 became almost like a part of my body and 42 00:02:07,310 --> 00:02:05,759 and every time Swift discovered 43 00:02:07,760 --> 00:02:07,320 something unforeseen or a gamma-ray 44 00:02:09,979 --> 00:02:07,770 burst 45 00:02:11,390 --> 00:02:09,989 went off the BlackBerry star bright 46 00:02:13,039 --> 00:02:11,400 vibrating and I would 47 00:02:14,390 --> 00:02:13,049 run to the nearest computer as fast as I 48 00:02:17,119 --> 00:02:14,400 could 49 00:02:18,440 --> 00:02:17,129 and and this is something I miss now not 50 00:02:20,990 --> 00:02:18,450 working anymore for Swift this 51 00:02:23,289 --> 00:02:21,000 excitement that things can happen at any 52 00:02:26,960 --> 00:02:23,299 time and you don't know what it is I 53 00:02:29,319 --> 00:02:26,970 have on two occasions gotten a gamma-ray 54 00:02:33,170 --> 00:02:29,329 burst alert while I was giving a lecture 55 00:02:35,000 --> 00:02:33,180 about Swift and so I told the audience 56 00:02:37,699 --> 00:02:35,010 that here's the new gamma-ray burst 57 00:02:40,640 --> 00:02:37,709 coming in and we actually one time got 58 00:02:42,199 --> 00:02:40,650 it on the screen and watched the data as 59 00:02:45,949 --> 00:02:42,209 they were coming in in front of the 60 00:02:48,860 --> 00:02:45,959 audience I was woken up by GRB own I 61 00:02:51,050 --> 00:02:48,870 know 423 it was 4:00 in the morning it 62 00:02:52,849 --> 00:02:51,060 was really annoying it was five years 63 00:02:55,490 --> 00:02:52,859 into the mission so geo views were not 64 00:02:58,250 --> 00:02:55,500 so new and exciting then I was like oh 65 00:03:00,349 --> 00:02:58,260 yeah yet another GRB dealt with it went 66 00:03:02,539 --> 00:03:00,359 back to sleep woke up the next morning 67 00:03:04,039 --> 00:03:02,549 and there was information from 68 00:03:05,990 --> 00:03:04,049 ground-based telescopes that had 69 00:03:07,789 --> 00:03:06,000 observed this gamma-ray burst in the 70 00:03:09,770 --> 00:03:07,799 infrared that we're implying that it was 71 00:03:11,509 --> 00:03:09,780 a very distant gamma-ray burst at 72 00:03:14,740 --> 00:03:11,519 redshifts greater than each that was 73 00:03:18,319 --> 00:03:14,750 very exciting and the next night 74 00:03:19,879 --> 00:03:18,329 telescopes in Hawaii were able to 75 00:03:22,490 --> 00:03:19,889 confirm that redshift that it's at a 76 00:03:25,759 --> 00:03:22,500 redshift of Z of 8.2 that means that 77 00:03:28,339 --> 00:03:25,769 gamma ray bursts went off more than 13 78 00:03:30,770 --> 00:03:28,349 billion years ago it's 13 billion light 79 00:03:33,379 --> 00:03:30,780 years away we're seeing light that from 80 00:03:36,229 --> 00:03:33,389 a star that was only 700 million years 81 00:03:38,270 --> 00:03:36,239 after the Big Bang that's one of the 82 00:03:41,449 --> 00:03:38,280 most distant objects has ever been 83 00:03:43,580 --> 00:03:41,459 detected that was very cool in my case I 84 00:03:47,240 --> 00:03:43,590 had a different experience where it was 85 00:03:48,949 --> 00:03:47,250 Thanksgiving and we had my family and I 86 00:03:50,629 --> 00:03:48,959 had spent a large amount of time working 87 00:03:52,939 --> 00:03:50,639 to prevent the Thanksgiving dinner we 88 00:03:54,349 --> 00:03:52,949 had friends around and everything was 89 00:03:56,689 --> 00:03:54,359 ready the food was on the table 90 00:03:59,990 --> 00:03:56,699 and right as I put my fork into my 91 00:04:01,699 --> 00:04:00,000 turkey the my phone went off something 92 00:04:04,879 --> 00:04:01,709 had exploded in the universe with the 93 00:04:06,830 --> 00:04:04,889 detected it and we had to go to work so 94 00:04:10,899 --> 00:04:06,840 it doesn't always happen at convenient 95 00:04:13,819 --> 00:04:10,909 times but it is still exciting basically 96 00:04:16,250 --> 00:04:13,829 I'm on call 24 hours a day so it's hard 97 00:04:17,960 --> 00:04:16,260 to decide where my personal life starts 98 00:04:22,370 --> 00:04:17,970 and where my as Swift professional life 99 00:04:23,540 --> 00:04:22,380 ends as the astronomy and astrophysics 100 00:04:26,210 --> 00:04:23,550 community has 101 00:04:28,279 --> 00:04:26,220 engaged with Swift the scientists have 102 00:04:32,390 --> 00:04:28,289 learned new ways to use the observatory 103 00:04:35,390 --> 00:04:32,400 and its ability to rapidly follow up new 104 00:04:38,390 --> 00:04:35,400 sources has been seen as a really 105 00:04:40,040 --> 00:04:38,400 incredibly useful tool and so Swift is 106 00:04:41,960 --> 00:04:40,050 evolved from spending most of its time 107 00:04:43,520 --> 00:04:41,970 observing gamma-ray bursts and following 108 00:04:46,820 --> 00:04:43,530 them for sometimes weeks or months 109 00:04:48,619 --> 00:04:46,830 afterwards to doing more science that's 110 00:04:51,260 --> 00:04:48,629 proposed by the community to study other 111 00:04:55,930 --> 00:04:51,270 types of objects we look at supernova 112 00:04:59,240 --> 00:04:55,940 novi black hole transients comets 113 00:05:02,360 --> 00:04:59,250 flaring stars all different kinds of 114 00:05:04,490 --> 00:05:02,370 objects basically every year Swift makes 115 00:05:06,350 --> 00:05:04,500 a new discovery that changes some field 116 00:05:08,180 --> 00:05:06,360 of astrophysics we have made many many 117 00:05:09,619 --> 00:05:08,190 discoveries in other areas we've 118 00:05:11,959 --> 00:05:09,629 discovered something called a tidal 119 00:05:13,520 --> 00:05:11,969 disruption event that's when a star is 120 00:05:15,409 --> 00:05:13,530 falling into a black hole and gets 121 00:05:17,059 --> 00:05:15,419 ripped to shreds and we see the light 122 00:05:19,580 --> 00:05:17,069 from that collapse onto the black hole 123 00:05:21,439 --> 00:05:19,590 that's very very exciting we've made 124 00:05:23,270 --> 00:05:21,449 important discoveries about comets 125 00:05:25,129 --> 00:05:23,280 how much water and how much other 126 00:05:27,529 --> 00:05:25,139 material there is in comets that people 127 00:05:30,350 --> 00:05:27,539 didn't know before we have actually seen 128 00:05:32,990 --> 00:05:30,360 a supernova star that blows up at the 129 00:05:36,050 --> 00:05:33,000 moment when the light broke out from the 130 00:05:38,120 --> 00:05:36,060 surface of the exploding star every year 131 00:05:40,610 --> 00:05:38,130 for the ten years of Swift we've had one 132 00:05:44,480 --> 00:05:40,620 of these really important discoveries it 133 00:05:47,779 --> 00:05:44,490 is the Cadillac of satellites it does 134 00:05:51,860 --> 00:05:47,789 everything in the transient filter in 135 00:05:54,920 --> 00:05:51,870 one package and mind you this is a small 136 00:05:58,610 --> 00:05:54,930 packets it's an Explorer mission we have 137 00:06:00,680 --> 00:05:58,620 a huge amount of capability Swift's 138 00:06:02,480 --> 00:06:00,690 ability to observe many objects in one 139 00:06:04,219 --> 00:06:02,490 day I think is what makes it special as 140 00:06:06,769 --> 00:06:04,229 well as its ability to respond very 141 00:06:08,839 --> 00:06:06,779 quickly to new events in the in the 142 00:06:12,439 --> 00:06:08,849 universe norther mission is as agile as 143 00:06:14,860 --> 00:06:12,449 we are Swift performs every day five to 144 00:06:17,659 --> 00:06:14,870 seven target of opportunities or 145 00:06:19,969 --> 00:06:17,669 societal requested by the astronomers to 146 00:06:22,399 --> 00:06:19,979 be observed and they are observed every 147 00:06:24,649 --> 00:06:22,409 days and and this is a very powerful 148 00:06:27,830 --> 00:06:24,659 capability that the community now is 149 00:06:30,290 --> 00:06:27,840 taking advantage of I knew the 150 00:06:32,659 --> 00:06:30,300 instrument I knew its capabilities but 151 00:06:34,460 --> 00:06:32,669 I've been extremely impressed with the 152 00:06:37,040 --> 00:06:34,470 team of people that behind 153 00:06:40,640 --> 00:06:37,050 the scenes make the mission work there 154 00:06:44,030 --> 00:06:40,650 is a group of duty scientists mission 155 00:06:46,970 --> 00:06:44,040 planners the flight operations team that 156 00:06:50,300 --> 00:06:46,980 make sure that we can continue to 157 00:06:53,240 --> 00:06:50,310 observe as many targets as we do we can 158 00:06:55,490 --> 00:06:53,250 continue to do the rapid response that 159 00:06:58,040 --> 00:06:55,500 is really unique to the observatory and 160 00:07:00,980 --> 00:06:58,050 without such a dedicated crew of people 161 00:07:02,840 --> 00:07:00,990 behind the scenes I don't think so it 162 00:07:07,280 --> 00:07:02,850 would be nearly as successful as it has 163 00:07:11,750 --> 00:07:07,290 been Swift mission has been extremely 164 00:07:15,830 --> 00:07:11,760 successful in the past up to now and it 165 00:07:20,270 --> 00:07:15,840 will no doubt continue to be successful 166 00:07:24,470 --> 00:07:20,280 in the future and I am sure that a lot 167 00:07:28,790 --> 00:07:24,480 of serendipitous science is just waiting 168 00:07:31,820 --> 00:07:28,800 for us the universe has a lot of Secrets 169 00:07:35,180 --> 00:07:31,830 that have not been revealed yet we do 170 00:07:39,080 --> 00:07:35,190 believe that shrift can and will reveal 171 00:07:41,540 --> 00:07:39,090 many more mysteries and puzzles in the 172 00:07:44,060 --> 00:07:41,550 universe we don't know what will happen 173 00:07:47,150 --> 00:07:44,070 over the next 10 years hoping that Swift 174 00:07:50,000 --> 00:07:47,160 will still give us exciting data but 175 00:07:52,400 --> 00:07:50,010 what we do know is that Swift will give 176 00:07:55,700 --> 00:07:52,410 us exciting new data because of its pure 177 00:07:58,250 --> 00:07:55,710 nature this is what it was built for to 178 00:08:00,530 --> 00:07:58,260 study new unforeseen unexpected events 179 00:08:04,400 --> 00:08:00,540 and they will inevitably happen it's 180 00:08:08,090 --> 00:08:04,410 been a part of my life every day for the 181 00:08:11,450 --> 00:08:08,100 last 20 years I love it it's produced so 182 00:08:14,590 --> 00:08:11,460 much great science and it's been very 183 00:08:18,980 --> 00:08:14,600 fulfilling but every day I think about 184 00:08:21,490 --> 00:08:18,990 this delicate instrumentation in the 185 00:08:24,560 --> 00:08:21,500 harsh environment orbiting the Earth and 186 00:08:27,050 --> 00:08:24,570 how its able to keep going all of those 187 00:08:30,720 --> 00:08:27,060 years and I very often will just look up
