1 00:00:10,301 --> 00:00:12,053 SphereX is NASA's 2 00:00:12,053 --> 00:00:15,515 latest explorer mission in astrophysics, and I'm very excited about it. 3 00:00:15,849 --> 00:00:18,601 Sphere X is going to answer some fundamental questions. 4 00:00:18,601 --> 00:00:22,731 It's going to tell us about the origin of the universe, the birth and formation 5 00:00:22,731 --> 00:00:27,360 history of galaxies, and the abundance of essential molecules 6 00:00:27,360 --> 00:00:30,405 such as water in the early stages of star 7 00:00:30,405 --> 00:00:33,408 and planet formation. 8 00:00:37,954 --> 00:00:41,082 In this catalog, we expect to have, spectra of 9 00:00:41,708 --> 00:00:45,587 of order, half a billion galaxies, hundreds of millions of stars. 10 00:00:45,795 --> 00:00:49,632 And because we're covering the entire sky, we can expect some unusual 11 00:00:49,632 --> 00:00:51,259 objects as well. 12 00:00:51,259 --> 00:00:55,263 We will expect to see some black holes. 13 00:00:55,263 --> 00:00:58,266 The first black holes to light up in the center of galaxies. 14 00:00:58,933 --> 00:01:01,853 In the early, early times at the edge of the universe. 15 00:01:01,853 --> 00:01:04,564 We can also expect to see, 16 00:01:04,564 --> 00:01:08,068 some rare events and stars in our own galaxy. 17 00:01:08,234 --> 00:01:12,072 Stars that are undergoing, bombardment period where comets 18 00:01:12,072 --> 00:01:17,285 and asteroids are coming into the inner solar system in these systems. 19 00:01:18,244 --> 00:01:19,996 And so it's going to be very exciting. 20 00:01:19,996 --> 00:01:22,999 And we expect, some discoveries from this. 21 00:01:29,756 --> 00:01:32,759 SphereX is unique because it, 22 00:01:32,884 --> 00:01:34,803 does something that hasn't been done before. 23 00:01:34,803 --> 00:01:37,097 It covers the entire sky. 24 00:01:37,097 --> 00:01:40,350 But instead of doing this, like in camera fashion, where we just take a picture, 25 00:01:40,642 --> 00:01:43,728 we're actually taking, what astronomers call a spectrum. 26 00:01:43,728 --> 00:01:46,731 We're splitting up the light into 27 00:01:46,815 --> 00:01:49,859 multiple wavelengths, and we take that spectrum everywhere on the sky. 28 00:01:50,610 --> 00:01:52,112 So that's a unique tool. 29 00:01:52,112 --> 00:01:56,032 And it, allows us, for example, to study inflation 30 00:01:56,032 --> 00:02:00,537 because we get the distances of galaxies through their spectra 31 00:02:00,829 --> 00:02:03,832 and we cover the entire sky that way. 32 00:02:10,421 --> 00:02:12,173 The wavelengths we're studying 33 00:02:12,173 --> 00:02:14,843 are out in the, near infrared. 34 00:02:14,843 --> 00:02:18,888 So, SphereX starts at wavelengths just beyond where your eye can see, 35 00:02:19,472 --> 00:02:22,475 the optical, to wavelengths that are about ten times longer, 36 00:02:23,143 --> 00:02:26,146 that, than than what we see here in the visible. 37 00:02:26,437 --> 00:02:27,647 And so that range is 38 00:02:27,647 --> 00:02:31,693 the range of interest for, seeing the fingerprints of galaxies, 39 00:02:31,693 --> 00:02:36,781 but also seeing the fingerprints from some important atoms and molecules. 40 00:02:43,037 --> 00:02:45,874 SphereX isn't a big telescope, but we can study the 41 00:02:45,874 --> 00:02:48,877 the imprints of galaxy formation, 42 00:02:48,918 --> 00:02:51,921 on, on large scales and, 43 00:02:53,339 --> 00:02:55,300 and we not only can 44 00:02:55,300 --> 00:02:58,928 see this, perhaps the beginnings of galaxy formation, 45 00:02:59,137 --> 00:03:02,974 we can actually map out its entire history. 46 00:03:03,224 --> 00:03:04,976 And we're not doing this in individual galaxies. 47 00:03:04,976 --> 00:03:08,980 We're kind of seeing the big picture over, multiple, 48 00:03:08,980 --> 00:03:11,983 multiple, galaxies. 49 00:03:17,155 --> 00:03:19,449 And so SphereX is going to study the, 50 00:03:19,449 --> 00:03:24,370 abundance of, of ices, water, but also important species 51 00:03:24,370 --> 00:03:29,042 that are have key materials for life, such as carbon dioxide and methanol. 52 00:03:29,417 --> 00:03:31,836 It's going to study the abundance of those ices 53 00:03:31,836 --> 00:03:35,882 in the early stages of star formation, going from the dense 54 00:03:35,882 --> 00:03:39,677 molecular clouds before there were stars to the early stages of stars, 55 00:03:39,677 --> 00:03:44,891 turn on and form these material disks that eventually turn into planetary systems.
