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.
