1
00:00:02,960 --> 00:00:04,920
The main finding we're talking

2
00:00:04,920 --> 00:00:08,680
about today of the GLASS JWST program, is the discovery

3
00:00:08,680 --> 00:00:12,560
that there’s lots of bright galaxies
in the early universe

4
00:00:12,800 --> 00:00:18,200
and galaxies formed faster and earlier
than we thought before.

5
00:00:18,520 --> 00:00:21,240
Our two main science goals
were first to find out how and when

6
00:00:21,240 --> 00:00:22,640
the first galaxies formed,

7
00:00:23,280 --> 00:00:24,480
and then to find out when

8
00:00:24,480 --> 00:00:27,760
and how fast the heavier elements like carbon 
and oxygen are formed.

9
00:00:28,720 --> 00:00:30,560
So really it’s a quest for the beginning.

10
00:00:30,560 --> 00:00:32,800
How did it all begin?

11
00:00:32,800 --> 00:00:36,080
And all the data we‘ve gathered so far 
point towards star formation

12
00:00:36,080 --> 00:00:40,640
starting earlier and proceeding
faster than we anticipated.

13
00:00:40,640 --> 00:00:45,280
you know and this is only possible now 
because James Webb has unprecedented

14
00:00:45,760 --> 00:00:48,520
light gathering power, it can see objects that are fainter

15
00:00:48,520 --> 00:00:50,280
than we could see before.

16
00:00:51,640 --> 00:00:57,120
So in this image there are about
6,000 galaxies that can be detected.

17
00:00:57,720 --> 00:01:01,880
And to give you an idea
of how mind blowing that is,

18
00:01:02,400 --> 00:01:05,600
the size of that field in the sky

19
00:01:05,640 --> 00:01:09,640
is equivalent to a grain of sand held at arm’s length.

20
00:01:10,320 --> 00:01:13,920
So in just a tiny,
tiny portion of the sky, much smaller

21
00:01:13,920 --> 00:01:18,560
than the moon, much smaller than any planet that you can see with your naked eye, 

22
00:01:18,560 --> 00:01:20,960
we detected 6,000 galaxies.

23
00:01:21,080 --> 00:01:24,560
And this is just
the awesomeness of JWST.

24
00:01:24,560 --> 00:01:26,320
To me, this is significant.

25
00:01:26,320 --> 00:01:30,280
The telescope is performing
better than we expected.

26
00:01:30,280 --> 00:01:32,640
You know, the performance is just extraordinary,

27
00:01:32,640 --> 00:01:35,040
and the universe is cooperating.

28
00:01:35,760 --> 00:01:37,520
I mean, and this has been

29
00:01:37,520 --> 00:01:42,000
the most exciting time of my life
scientifically.
