00:00:07,140 --> 00:00:09,640
How did we get here?

4
00:00:09,640 --> 00:00:13,270
Big questions about who we are
and how we got to be that way

5
00:00:13,270 --> 00:00:16,219
are at the core of our nature.

6
00:00:16,219 --> 00:00:20,440
We've developed technology to
see amazingly far across space

7
00:00:20,440 --> 00:00:22,200
and also time.

00:00:23,840 --> 00:00:28,800
Light moves through space, just
like we do, only much faster.

10
00:00:28,800 --> 00:00:32,600
It takes time to get somewhere.

11
00:00:32,600 --> 00:00:36,790
So, viewing the light of
distant stars and galaxies

12
00:00:36,790 --> 00:00:38,710
is like looking into the past.

13
00:00:38,710 --> 00:00:43,130
It took time for the
light to reach us.

14
00:00:43,130 --> 00:00:47,120
Yet, after all our years of
exploring to better understand

15
00:00:47,120 --> 00:00:53,366
ourselves and our origins,
there is still so much to know.

[MUSIC PLAYING]

17
00:00:55,560 --> 00:00:59,820
Our story stretches back
more than 13 billion years,

18
00:00:59,820 --> 00:01:04,676
not long after the expansion
of time and space first began.

19

[MUSIC PLAYING]

20
00:01:08,010 --> 00:01:11,280
At some unknown time, the
building blocks of life

21
00:01:11,280 --> 00:01:15,850
were forged in the heart
of the first stars.

22
00:01:15,850 --> 00:01:19,580
But much of the early
universe remains a mystery.

23
00:01:19,580 --> 00:01:21,340
[MUSIC PLAYING]

24
00:01:21,340 --> 00:01:23,890
There are theories
about how gravity first

25
00:01:23,890 --> 00:01:26,740
brought stars, gas,
and dark matter

26
00:01:26,740 --> 00:01:29,380
together to form galaxies.

27
00:01:29,380 --> 00:01:33,066
But that time period
has never been observed.

29
00:01:34,850 --> 00:01:37,460
Detecting light from the
first galaxies to form

30
00:01:37,460 --> 00:01:41,391
has been a challenge for even
the most powerful telescopes.

31

[MUSIC PLAYING]

32
00:01:44,280 --> 00:01:46,380
As the light early
galaxies emitted

33
00:01:46,380 --> 00:01:51,840
traveled through space, that
space itself was expanding,

34
00:01:51,840 --> 00:01:55,770
stretching the light to
longer infrared wavelengths.

00:01:59,214 --> 00:02:00,200


37
00:02:00,200 --> 00:02:03,870
Past telescopes have
detected infrared light,

38
00:02:03,870 --> 00:02:07,740
but the faint light of
the very first galaxies

39
00:02:07,740 --> 00:02:13,170
has remained out
of reach until now.

40
00:02:13,170 --> 00:02:16,890
The James Webb Space Telescope
is specially designed

41
00:02:16,890 --> 00:02:19,170
to detect the first galaxies.

43
00:02:21,480 --> 00:02:24,480
Webb's large mirror and
sensitive instruments

44
00:02:24,480 --> 00:02:26,970
will enable it to collect
more infrared light

45
00:02:26,970 --> 00:02:34,860
than we've ever seen, allowing
the first galaxies to emerge

46
00:02:34,860 --> 00:02:36,380
into view.

48
00:02:38,020 --> 00:02:42,160
With Webb, we can begin filling
in some of the blank pages

49
00:02:42,160 --> 00:02:46,460
at the beginning of
the universe's story.

50
00:02:46,460 --> 00:02:49,520
When did the first
galaxies form?

51
00:02:49,520 --> 00:02:51,630
How massive were they?

52
00:02:51,630 --> 00:02:55,733
What types of stars and
elements did they contain?

53
00:02:55,733 --> 00:02:57,850
[MUSIC PLAYING]

54
00:02:57,850 --> 00:03:01,300
The universe's
story is our story.

55
00:03:01,300 --> 00:03:05,170
And with Webb, we can finally
explore these questions

56
00:03:05,170 --> 00:03:09,610
as well as uncover new ones we
haven't even thought to ask.
