00:00:04,000 --> 00:00:10,000
In 2003, the Hubble Space Telescope pointed at a dark, empty patch of sky.

00:00:10,000 --> 00:00:12,000


4
00:00:12,000 --> 00:00:18,000
It watched this spot for 270 hours, patiently collecting light…

5
00:00:18,000 --> 00:00:24,000


6
00:00:24,000 --> 00:00:30,000
and found the most distant galaxies known.

7
00:00:30,000 --> 00:00:36,000


8
00:00:36,000 --> 00:00:42,000
10,000 galaxies in one tiny patch of sky.

00:00:42,000 --> 00:00:46,000


10
00:00:46,000 --> 00:00:52,000
Forever changing our understanding of how truly vast the universe is,

11
00:00:52,000 --> 00:00:55,000


12
00:00:55,000 --> 00:01:01,000
and how many galaxies are out there.

13
00:01:01,000 --> 00:01:04,000


14
00:01:04,000 --> 00:01:10,000
The Nancy Grace Roman Space Telescope could do the same thing…

15
00:01:10,000 --> 00:01:16,270
on a much larger scale.

16
00:01:16,270 --> 00:01:19,270


17
00:01:19,270 --> 00:01:29,710
There is no telling what we might learn.
