WATCH LIVE: The 'blood moon' total lunar eclipse
The moon will turn red, which is normal for a lunar eclipse, but this rare event will be bigger and brighter than those of the past few decades. That's because the eclipse will coincide with a supermoon - a "very rare" alignment that won't happen again until 2033.
Check this map to see if you live where the eclipse will be visible. If you don't live in a visible region, or a big city with too many tall obstructions or a lot of light pollution, bookmark this page.
