1 00:00:00,100 --> 00:00:04,150 Another one of the big goals of the James Webb Space Telescope is to see how 2 00:00:04,170 --> 00:00:08,230 planetary systems got their start. So that would be akin to thinking about 3 00:00:08,250 --> 00:00:12,330 how our solar system was several billion years ago. So looking 4 00:00:12,350 --> 00:00:16,460 at the big disks of gas and dust that eventually 5 00:00:16,480 --> 00:00:20,560 form stars and planets. Another really great thing about 6 00:00:20,580 --> 00:00:24,700 Webb being an infrared telescope is the fact that a lot of the really interesting 7 00:00:24,720 --> 00:00:28,770 components in a planet's atmosphere happen to fall in the infrared part 8 00:00:28,790 --> 00:00:32,850 of the spectrum. When a star has a planet that goes in front of the star 9 00:00:32,870 --> 00:00:36,960 and blocks some of the starlight we can say ah, now we know how big that planet was 10 00:00:36,980 --> 00:00:41,050 and also we can begin to explore the light that goes through the planet's atmosphere on its 11 00:00:41,070 --> 00:00:45,150 to our telescope. We spread that out into a spectrum as well and we can see can now 12 00:00:45,170 --> 00:00:49,330 now what chemical in the atmosphere of another planet. So for 13 00:00:49,350 --> 00:00:53,360 example we can look for things like water vapor or carbon dioxide 14 00:00:53,380 --> 00:00:57,440 those types of things. So the Webb telescope is definitely our next 15 00:00:57,460 --> 00:01:00,007 step in our search for life in the universe.
