00:00:00.000 --> 00:00:04.000
The James Webb Space Telescope is impressive.

2
00:00:04.000 --> 00:00:08.000
It's three stories tall, as wide as a tennis court.

3
00:00:08.000 --> 00:00:12.000
It's got a 21 foot primary mirror

4
00:00:12.000 --> 00:00:16.000
and then it's got these 4 instruments that are just incredibly powerful.

5
00:00:16.000 --> 00:00:20.000
It's the largest, most technologically challenging space telescope ever created.

6
00:00:20.000 --> 00:00:24.000
It's one hundred times more powerful than the Hubble Space Telescope

7
00:00:24.000 --> 00:00:28.000
but at half the weight.

8
00:00:28.000 --> 00:00:32.000
It's designed to look back in time even further than Hubble

9
00:00:32.000 --> 00:00:36.000
to see the very first galaxies to form after the Big Bang.

10
00:00:36.000 --> 00:00:40.000
Building Webb is truly a feat of innovative engineering

11
00:00:40.000 --> 00:00:44.000
each material must survive the turmoil of a launch and the

12
00:00:44.000 --> 00:00:48.000
varying temperatures of space - and it all starts with

13
00:00:48.000 --> 00:00:52.000
the elements.

14
00:00:52.000 --> 00:00:56.000
music

15
00:00:56.000 --> 00:01:00.000
music

16
00:01:00.000 --> 00:01:04.000
music

17
00:01:04.000 --> 00:01:08.000
music

18
00:01:08.000 --> 00:01:12.981
This is the James Webb Space Telescope!
