00:00:00.466 --> 00:00:01.866
Annular eclipse.

2
00:00:01.866 --> 00:00:05.400
An annular solar eclipse occurs when the Moon
passes between

3
00:00:05.400 --> 00:00:10.166
the Sun and Earth
while at or near
its farthest point
away from Earth.

4
00:00:10.233 --> 00:00:13.366
The relative distances
between the Sun, Moon
and Earth

5
00:00:13.600 --> 00:00:16.900
make the Moon appear
almost big enough to
block out the Sun.

6
00:00:17.000 --> 00:00:18.200
But not quite.

7
00:00:18.200 --> 00:00:21.833
This creates the
optical illusion
of a ring of fire
in the sky.

8
00:00:21.933 --> 00:00:23.000
This is in contrast

9
00:00:23.000 --> 00:00:26.733
to a total solar eclipse,
where the Moon is a little closer to Earth

10
00:00:26.933 --> 00:00:30.933
and can fully block
out the Sun, darkening
the sky for a short
amount of time.

11
00:00:31.100 --> 00:00:32.133
And get this.

12
00:00:32.133 --> 00:00:35.133
Our planet is not the
only one that has
solar eclipses.

13
00:00:35.300 --> 00:00:39.033
For example, Saturn
has hundreds of moons
and several rings.

14
00:00:39.100 --> 00:00:42.600
Eclipses happen
frequently as moons
and icy ring particles

15
00:00:42.600 --> 00:00:44.733
pass between Saturn
and the Sun.

16
00:00:44.733 --> 00:00:47.733
The Cassini spacecraft
has even captured
some on camera.

17
00:00:47.900 --> 00:00:51.066
Now, while observing
annular eclipses from
here on Earth,

18
00:00:51.133 --> 00:00:54.633
do it properly and don't look directly at the
Sun without special

19
00:00:54.833 --> 00:00:57.833
eye protection designed
for solar viewing.

20
00:00:57.933 --> 00:00:58.566
Happy viewing!
