Lunar Eclipse

There are always headlines when a blood moon is coming, but they don't always explain what a blood moon is - and how it differs from a lunar eclipse. A blood moon is the same thing as a total lunar eclipse (one of three types of lunar eclipses that can be seen from Earth). Whenever you read a news story about an upcoming blood moon - or see beautiful pictures of one that has just happened - the scientifically accurate term for what you're seeing is a total lunar eclipse. To help make more sense of the blood moon phenomena, it helps to understand how eclipses work. An eclipse occurs any time one celestial body (such as Earth or the moon) passes in between the sun and another celestial body and casts a shadow on that other object. In the case of a lunar eclipse, Earth passes between the sun and the moon and our shadow is cast onto the moon.
