1 00:00:00,000 --> 00:00:01,668 [Music throughout] [Far and Wide Part 1: Surveying the Universe] 2 00:00:01,668 --> 00:00:03,970 The Nancy Grace Roman and James Webb Space 3 00:00:03,970 --> 00:00:07,540 Telescopes have very different approaches to studying the universe. 4 00:00:08,775 --> 00:00:11,711 Webb will see galaxies that are extremely far away, 5 00:00:11,711 --> 00:00:14,714 whose light was emitted when the universe was very young. 6 00:00:15,415 --> 00:00:17,917 It will reveal an early universe that scientists 7 00:00:17,917 --> 00:00:20,920 have only explored through calculations. 8 00:00:21,287 --> 00:00:24,724 We have very little information about the cosmos’ infancy, 9 00:00:25,058 --> 00:00:28,528 and Webb will help us fill in many of the gaps by making direct 10 00:00:28,528 --> 00:00:31,464 observations of galaxies as far into the past 11 00:00:31,464 --> 00:00:32,665 as physically possible. 12 00:00:33,833 --> 00:00:35,268 Roman, on the other hand, 13 00:00:35,268 --> 00:00:38,405 will use the power of its wide sky coverage to survey 14 00:00:38,405 --> 00:00:40,206 massive regions of space, 15 00:00:40,206 --> 00:00:43,076 documenting significant portions of the universe 16 00:00:43,076 --> 00:00:45,545 through its adolescent and early adult years. 17 00:00:46,312 --> 00:00:50,417 Roman will be able to survey thousands of square degrees of sky during its 18 00:00:50,417 --> 00:00:53,953 primary mission, enabling studies that were never possible before. 19 00:00:56,189 --> 00:00:58,591 Only by studying millions of galaxies can scientists 20 00:00:58,591 --> 00:01:02,629 begin to determine the behavior of the universe as a whole. 21 00:01:02,629 --> 00:01:05,965 Like its large-scale structure and how it has changed over time. 22 00:01:09,335 --> 00:01:14,841 [Learn more at science.nasa.gov/roman-and-webb]
