00:00:05,829 --> 00:00:03,110
hi i'm peter cullen the voice of

2
00:00:08,470 --> 00:00:05,839
transformers optimus prime

3
00:00:10,790 --> 00:00:08,480
during the last 24 years

4
00:00:12,629 --> 00:00:10,800
nasa's hubble space telescope has

5
00:00:14,549 --> 00:00:12,639
brought the wonders of the universe to

6
00:00:17,029 --> 00:00:14,559
us here on earth

7
00:00:19,750 --> 00:00:17,039
but as powerful as hubble is

8
00:00:22,710 --> 00:00:19,760
there are secrets about the cosmos that

9
00:00:25,029 --> 00:00:22,720
even it cannot reveal

10
00:00:27,349 --> 00:00:25,039
to unlock those secrets

11
00:00:28,870 --> 00:00:27,359
nasa is building hubble's scientific

12
00:00:32,470 --> 00:00:28,880
successor

13
00:00:35,430 --> 00:00:32,480
the james webb space telescope

14
00:00:38,229 --> 00:00:35,440
webb will be much larger than hubble

15
00:00:41,270 --> 00:00:38,239
so large that it must be folded to fit

16
00:00:42,950 --> 00:00:41,280
into its rocket for launch

17
00:00:45,990 --> 00:00:42,960
once in orbit

18
00:00:49,430 --> 00:00:46,000
one million miles from earth

19
00:00:53,350 --> 00:00:49,440
webb will transform into an observatory

20
00:00:56,950 --> 00:00:53,360
with a tennis court-sized sun shield

21
00:00:59,349 --> 00:00:56,960
and 21 foot wide primary mirror

22
00:01:02,709 --> 00:00:59,359
from a million miles away

23
00:01:04,869 --> 00:01:02,719
webb will be able to peer back in time

24
00:01:08,149 --> 00:01:04,879
to see the universe light up with its

25
00:01:11,190 --> 00:01:08,159
first stars and galaxies

26
00:01:13,109 --> 00:01:11,200
witness galaxies evolve across cosmic

27
00:01:15,830 --> 00:01:13,119
time

28
00:01:18,550 --> 00:01:15,840
and even explore the atmospheres

29
00:01:21,590 --> 00:01:18,560
of alien worlds

30
00:01:24,469 --> 00:01:21,600
the james webb space telescope
