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.
