Which parts of the sky can
the Webb telescope see?

00:00:07.540 --> 00:00:14.320 align:middle line:90%


00:00:14.320 --> 00:00:17.290 align:middle line:84%
The James Webb Space Telescope
orbits the sun in sync

00:00:17.290 --> 00:00:22.440 align:middle line:84%
with Earth but one million miles
further out beyond the moon.

00:00:22.440 --> 00:00:27.210 align:middle line:90%


00:00:27.210 --> 00:00:29.100 align:middle line:84%
The telescope's mirror
is perpendicular

00:00:29.100 --> 00:00:31.530 align:middle line:84%
to the 70-foot sunshield,
which keeps it cool.

00:00:31.530 --> 00:00:35.480 align:middle line:90%


00:00:35.480 --> 00:00:38.360 align:middle line:84%
The telescope's movement is
limited in certain directions

00:00:38.360 --> 00:00:40.310 align:middle line:84%
to keep the mirror and
scientific instruments

00:00:40.310 --> 00:00:41.858 align:middle line:84%
in the shade of the
sunshield blocked

00:00:41.858 --> 00:00:42.900 align:middle line:90%
from the heat of the sun.

00:00:42.900 --> 00:00:49.950 align:middle line:90%


00:00:49.950 --> 00:00:53.460 align:middle line:84%
But Webb can rotate to get a
360-degree view of the sky.

00:00:53.460 --> 00:01:03.320 align:middle line:90%


00:01:03.320 --> 00:01:06.290 align:middle line:84%
As Webb orbits the sun,
different celestial objects

00:01:06.290 --> 00:01:07.930 align:middle line:84%
enter its available
field of view.

00:01:07.930 --> 00:01:12.200 align:middle line:90%


00:01:12.200 --> 00:01:14.090 align:middle line:84%
Science observations
with the telescope

00:01:14.090 --> 00:01:16.880 align:middle line:84%
will be carefully scheduled
to make the most effective use

00:01:16.880 --> 00:01:17.750 align:middle line:90%
of Webb's time.

00:01:17.750 --> 00:01:23.140 align:middle line:90%


00:01:23.140 --> 00:01:25.180 align:middle line:84%
Over the course of
six months, Webb

00:01:25.180 --> 00:01:39.200 align:middle line:84%
has access to the entire
sky, allowing astronomers

00:01:39.200 --> 00:01:41.060 align:middle line:84%
to investigate a
range of questions

00:01:41.060 --> 00:01:43.850 align:middle line:84%
about how the universe works
and our place in the cosmos.
