If you're thinking the moon is looking particularly foreboding, don't worry. Your eyes aren't playing tricks, and nor is it the end of days, but a lunar phenomenon that happens once roughly every 30 years. If you look outside now, you'll see a supermoon lunar eclipse: a combination of a very nearby moon -- making it look up to 14 percent bigger -- and reflected orange hue from the sun, which is lined up with the moon and the Earth. Get your camera out (or hold your phone real steady), and go outside. But if you don't really like "outside", NASA's offering its own livestream right here. And if you miss it, you'll just have to wait til 2033.
