1. Eclipses
When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs.
There are 2 types of eclipses: solar (sun) eclipse & lunar (moon) eclipse.
The type of eclipse is named for what is being blocked from Earth.
Total solar eclipse Total lunar eclipse

2. Solar Eclipse
The umbra is the darkest and smallest part of the shadow & is cone shaped (total darkness).
The penumbra is the largest part of the shadow (partial darkness).
Total Solar Eclipse:
Only people in the umbra experience a total solar eclipse.
Partial Solar Eclipse:
In the penumbra, people only see a partial eclipse; since part of the sun is still visible, it is not safe to look directly at the eclipse.

3. Lunar Eclipse Total Lunar Eclipse
During a full moon the Earth blocks the sun’s light from reaching the moon making the moon look dark from Earth.
Total Lunar Eclipse
When the moon is in the Earth’s umbra, there is a total lunar eclipse
Partial Lunar Eclipse
The moon passes partly into the umbra of the Earth’s shadow.
