When the moon passes through the Earth's shadow, it causes the Moon to look very unusual for a short period of time. This event is called a lunar eclipse, and it occurs roughly twice a year. Learn more about how lunar eclipses work in this video!

* To Note: This is an updated version of a previous video that has been edited to remove references to specific dates of lunar eclipses. The purpose of doing so was to create a version of this informational product that could be used more broadly in educational settings.
