The Magnificent Lunar Eclipse There are two types of eclipses. The eclipse that is going to be discussed in this document is the lunar eclipse. A lunar eclipse occurs when the moon goes through the earth's shadow. This can only happen during a full moon. There are three different types of lunar eclipses; penumbral, partial, and total. Penumbral lunar eclipses occur when the moon passes only within the earth's penumbral shadow and does not fall within the umbra. It is the most common lunar eclipse. A Partial Lunar eclipse happens when the moon is only partially covered by earth's umbral shadow. It is easier to notice because Earth's umbral shadow clearly darkens part of moon's face.

A total lunar eclipse occurs when the sun, earth and moon are nearly perfectly aligned. Particularly spectacular this is because the color of the moon is a crazy red color. Due to moon being entirely covered by Earth's umbra. Moon is red because earth's atmosphere bends some of the red light from the sun around earth and toward the moon.
