4. Lunar Eclipse
“What is a Lunar Eclipse?” asked the inquiring student.

5. 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.

6. 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.

8. 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.

12. PART TWO
SOLAR ECLIPSE

13. 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.

14. 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 ( ), 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).
