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!

These videos and animations are available in both standard formats as well as stereoscopic 3D for those who can view it. We've included left and right eye clips, a side-by-side version, and an anaglyph (red/blue) version of the narrated video, and left and right eye clips for each of the animations. The labels next to each link will help you pick!
