1 00:00:00,000 --> 00:00:01,735 [Music throughout] [Far and Wide Part 1: Differences] 2 00:00:01,735 --> 00:00:03,770 The James Webb Space Telescope is now 3 00:00:03,770 --> 00:00:07,207 a million miles from Earth and performing science operations. 4 00:00:08,241 --> 00:00:10,343 The Nancy Grace Roman Space Telescope 5 00:00:10,343 --> 00:00:13,313 is scheduled to launch by 2027. 6 00:00:14,047 --> 00:00:17,650 These two observatories are NASA's latest flagship missions 7 00:00:17,650 --> 00:00:20,553 in the tradition of Hubble, Chandra, and Spitzer. 8 00:00:21,187 --> 00:00:22,555 But why do we need both? 9 00:00:22,555 --> 00:00:24,657 And why do they look so different? 10 00:00:24,657 --> 00:00:28,495 The answer to both questions is that they are built to do different things. 11 00:00:29,062 --> 00:00:32,632 Webb has the exquisite sensitivity and wavelength range to capture 12 00:00:32,632 --> 00:00:36,102 detailed images deeper into the universe than ever before. 13 00:00:36,836 --> 00:00:41,041 Roman has an incredibly wide field of view to rapidly survey huge 14 00:00:41,041 --> 00:00:45,211 areas of sky, while still rivaling Hubble and Webb's resolving power. 15 00:00:45,912 --> 00:00:48,181 These two telescopes, with their different, 16 00:00:48,181 --> 00:00:52,585 but complementary, goals and strengths, will help us understand 17 00:00:52,585 --> 00:00:55,755 much more about the early days of the universe, 18 00:00:56,289 --> 00:00:58,792 how it has evolved since then, 19 00:00:58,792 --> 00:01:01,494 and what other worlds might be out there. 20 00:01:02,162 --> 00:01:07,667 [Learn more at science.nasa.gov/roman-and-webb]
