WHY DO WE ALWAYS SEE THE SAME SIDE OF THE MOON?

Two kinds:

Lunar eclipsesSolar eclipses Video clip on e

clipses

Shadow has two partsa. Umbra - total darkness where

total eclipse occurs.b. Penumbra - part of light is

blocked, where partial eclipse occurs.

Two kinds of eclipsesa. Lunar- earth casts a shadow on the MOON -

occurs only at Full moonb. Solar - moon casts a shadow on earth - occurs

only at new moon.3. Amount of light blocked is not always the same,

causes total and partial eclipses.

Animation of solar eclipse

Diamond ring effect just before or after a total solar eclipse.

This animation shows the relative sizes of the partial and total eclipse areas. The small, black dot is the umbra. You can see why not many people ever see a total eclipse.

This is a space shuttle photograph of an area of the Earth having a total solar eclipse.

Types of Solar Eclipses1. Total Solar Eclipses occur when the umbra of the Moon's

shadow touches a region on the surface of the Earth. 2. Partial Solar Eclipses occur when the penumbra of the

Moon's shadow passes over a region on the Earth's surface.

3. Annular Solar Eclipses occur when a region on the Earth's surface is in line with the umbra, but the distances are such that the tip of the umbra does not reach the Earth's surface.
