Black holes are massive things. Supermassive black holes, found at the center of most spiral galaxies, are packed with hundreds of millions (if not billions) of times the mass of a star, yet they fit in relatively small spaces. The point is, they've all got lots of mass, but astronomers just found one that makes every other black hole ever seen look small.
A while back, we brought you news of a supermassive black hole that was 17 billion times more massive than our sun, making it among the biggest black holes ever found. We didn't think they could get much bigger than that, but new research suggests they can, and there may be more of these monsters than we ever thought.
At the center of our galaxy is a black hole nine light-years wide and four million times more massive than our Sun. It's a monstrous astronomical creature that devours matter, and thanks to a very sophisticated telescope we've got a better picture of what that looks like.
The most exciting thing we can usually think of when we think of asteroids is how we might stop one from crashing into Earth someday, but now scientists have given us another bit of asteroid intrigue. A NASA probe just sent us images from one of the biggest space rocks in the asteroid belt, and they show some pretty strange topography.
The Mayan Apocalypse didn't happen last week, and we're all back to living our lives, but it turns out there's another opportunity for world-ending calamity on the horizon. There's an asteroid out there that could slam into our planet in 2040. But will it? NASA's got the answer.
