Discover what happens during a lunar eclipse in this video from NASA. The orbit of the Moon around Earth causes the monthly phases of the Moon; lunar eclipses occur when the Moon passes through Earth's shadow. The video shows how the appearance of the Moon changes as it passes through Earth's penumbra and umbra, and why Earth's atmosphere causes the Moon to look red during a lunar eclipse.
