More About Lunar Eclipses
A lunar eclipse happens when the Earth casts a shadow that blocks sunlight that normally reflects off of the moon. A total lunar eclipse can only happen when the sun, Earth and moon are perfectly aligned. During the time of total eclipse, the moon will often look reddish due to red and orange light being scattered by the atmosphere. This eerie, harmless effect has earned the tongue-in-cheek nickname "blood moon."
