1 00:00:06,119 --> 00:00:03,749 gamma-ray burst now turns out to be the 2 00:00:08,310 --> 00:00:06,129 largest explosions in the in the 3 00:00:12,150 --> 00:00:08,320 universe they occur about about once a 4 00:00:13,860 --> 00:00:12,160 day at the time we flew Batsy on the 5 00:00:15,180 --> 00:00:13,870 gamma ray Observatory they were a 6 00:00:17,730 --> 00:00:15,190 complete mystery 7 00:00:20,040 --> 00:00:17,740 people had no idea what they were all 8 00:00:21,960 --> 00:00:20,050 they knew is that from different parts 9 00:00:24,750 --> 00:00:21,970 of the sky they would see these 10 00:00:26,910 --> 00:00:24,760 tremendous flashes of gamma rays coming 11 00:00:29,009 --> 00:00:26,920 from different directions they only have 12 00:00:31,560 --> 00:00:29,019 lasted from a fraction of a second to 13 00:00:33,380 --> 00:00:31,570 several minutes but during this time 14 00:00:36,240 --> 00:00:33,390 they were brighter than all the other 15 00:00:39,810 --> 00:00:36,250 objects in the sky in a gamma ray part 16 00:00:41,340 --> 00:00:39,820 of the spectrum including the Sun we 17 00:00:43,020 --> 00:00:41,350 didn't even know how far away they were 18 00:00:44,700 --> 00:00:43,030 we didn't know if they were in the solar 19 00:00:47,370 --> 00:00:44,710 system we didn't know if they were in 20 00:00:50,490 --> 00:00:47,380 our galaxy or in some other distant 21 00:00:54,090 --> 00:00:50,500 galaxy what turns out due to the 22 00:00:57,360 --> 00:00:54,100 observations of Batsy and the Italian 23 00:00:59,250 --> 00:00:57,370 Dutch satellite Beppo sacks we 24 00:01:01,650 --> 00:00:59,260 determined that the gamma-ray bursts 25 00:01:03,870 --> 00:01:01,660 were coming from the farthest reaches of 26 00:01:07,200 --> 00:01:03,880 the universe in fact they were the most 27 00:01:10,230 --> 00:01:07,210 distant objects known much much further 28 00:01:13,890 --> 00:01:10,240 than people ever thought they were when 29 00:01:16,680 --> 00:01:13,900 G ro was launched ever since I was a boy 30 00:01:19,740 --> 00:01:16,690 in grade school I I liked or loved 31 00:01:22,410 --> 00:01:19,750 science I had a large chemistry 32 00:01:26,310 --> 00:01:22,420 laboratory in the basement of my my home 33 00:01:29,430 --> 00:01:26,320 in st. Louis where I grew up then of 34 00:01:32,610 --> 00:01:29,440 course I went on to get a degree in in 35 00:01:36,530 --> 00:01:32,620 physics and and then a PhD in space 36 00:01:40,200 --> 00:01:36,540 science what gives me the most reward is 37 00:01:42,780 --> 00:01:40,210 actually making progress in a field of 38 00:01:45,750 --> 00:01:42,790 science my own particular field is gamma 39 00:01:47,910 --> 00:01:45,760 ray astrophysics coming up with a new 40 00:01:51,270 --> 00:01:47,920 finding and then publishing that finding 41 00:01:52,980 --> 00:01:51,280 or presented in an a scientific meeting 42 00:01:55,440 --> 00:01:52,990 or conference really gives me the 43 00:01:58,080 --> 00:01:55,450 greatest pleasure now that I'm a more 44 00:02:01,350 --> 00:01:58,090 senior scientist I enjoy seeing the 45 00:02:05,010 --> 00:02:01,360 younger students starting out in their 46 00:02:08,279 --> 00:02:05,020 careers in astrophysics and giving the 47 00:02:11,370 --> 00:02:08,289 papers at conferences and publishing 48 00:02:12,830 --> 00:02:11,380 papers in the field this this now gives 49 00:02:15,320 --> 00:02:12,840 me a lot of pleasure 50 00:02:17,750 --> 00:02:15,330 I enjoy mentoring these these younger 51 00:02:21,170 --> 00:02:17,760 scientists that that will take our place 52 00:02:24,259 --> 00:02:21,180 when when we're no longer here I was 53 00:02:26,930 --> 00:02:24,269 completely amazed surprised and an honor 54 00:02:29,300 --> 00:02:26,940 to receive the the SHA prize in 55 00:02:31,789 --> 00:02:29,310 astronomy I'm looking forward to 56 00:02:35,089 --> 00:02:31,799 receiving the the SHA prize along with
