Welcome to hell. Sorry, I meant Venus. Some say it's Earth's twin. But this world is nothing like home. And you're about to experience this scorching hot landscape firsthand.

Just 3,000 light-years from Earth is a black hole visible to the naked eye. Thankfully, we are a safe distance from this stellar black hole and many others like it. There are approximately 100 million of them out there in our galaxy that we know of. They are the remnants of supernovae, which occur when stars 10 to 20 times larger than our Sun collapse in on themselves. Could a black hole devour us all one day? There are millions of them out there just waiting. And if we happened to make a black hole accidentally, well, you better fasten your seatbelts. Things are going to really suck! Quite literally. What would we see if we got pulled into a black hole? Could Earth orbit the Sun and a black hole? Would we survive spaghettification? What would happen if we get past the event horizon?

From year to year, the moon never seems to change. Craters and other formations appear to be permanent now, but the moon didn't always look like this. Thanks to NASA's Lunar Reconnaissance Orbiter, we now have a better look at some of the moon's history. Learn more in this video!

This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called “tidal disruptions,” some of the stellar debris is flung outward at high speed while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA’s Chandra X-ray Observatory, Swift Gamma-ray Burst Explorer, and ESA/NASA’s XMM-Newton collected different pieces of this astronomical puzzle in a tidal disruption event called ASASSN-14li, which was found in an optical search by the All-Sky Automated Survey for Supernovae (ASAS-SN) in November 2014. The event occurred near a supermassive black hole estimated to weigh a few million times the mass of the sun in the center of PGC 043234, a galaxy that lies about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models about how black holes affect their environments.
