Lunar Eclipse
“What is a Lunar Eclipse?” asked
the inquiring student.
Wally Wolf’s Answer:
A lunar eclipse occurs when the Earth's shadow
falls on the moon. Lunar eclipses occur, on
average, about every 6 months
Total Eclipse - When the entire moon enters the
Earth's umbra (the darkest part of its shadow),
this is called a total eclipse.
Partial Eclipse - When only part of the moon
enters the Earth's umbra, this is called a partial
eclipse.
How long do they last?

Duration of Lunar Eclipses
During an average total lunar eclipse, the moon
is within the Earth's umbra for about an hour.
This is called totality.

Lunar Eclipse Definitions
Earth - the planet on which we live.
Moon - the natural satellite of the Earth.
Penumbra - the area in which the shadow of an object
(in this case, the Earth on the moon) is partial.
Sun - the star in our Solar System.
Umbra - the area in which the shadow of an object (in
this case, the Earth on the moon) is total. When the
entire moon is in the Earth's umbra, we experience a
total lunar eclipse. When part of the moon is in the
Earth's umbra, we experience a partial lunar eclipse.

ECLIPSE
What is a Solar Eclipse?

A solar eclipse happens when the moon
blocks our view of the sun. This happens
when the Moon is exactly between the
Sun and the Earth.
What are the Solar Eclipse stages ?

1. BAILY'S BEADS:
Baily's beads (often spelled Bailey's beads) are bead-like bursts of
light that appear about 15 seconds before and after totality during a
solar eclipse. Baily's beads are caused by light shining through
valleys on the edge of the moon. They were named for the British
astronomer Francis Baily (1774-1844), one of the founders of the
Royal Astronomical Society.

2. DIAMOND RING:
The "Diamond Ring" is a large burst of light that appears a few
seconds before and after totality.

3. TOTALITY:
Totality is the short part of an eclipse when the moon entirely blocks
the Sun. Totality usually lasts for just a few minutes (no more than
8 minutes in any one location on Earth).
