Give your answer to this question below!
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. There's one viewable to folks outside of North America on June 15, so sit back and learn more about how lunar eclipses work in this video! This video is also available in stereoscopic 3D, viewable by many kinds of 3D devices, including common red/blue paper glasses that you might have lying around!
