The VLBA has observed two supermassive black holes orbiting each other in a gravitational dance.
We’ve never observed a black hole directly, but that could change soon.
How does a galaxy get rid of a supermassive black hole?
We haven’t completely ruled out black holes as the source of dark matter, but there are few mass ranges left.
What happens when you fall into a black hole? Maybe you could live a long and happy life.
A new x-ray deep field image supports the idea that supermassive black holes formed before galaxies did.
The brightest supernova observed may have been caused by a hungry black hole.
Observations of gravitational waves might allow us to test the quantum properties of black holes.
To make a black hole, do we have to squeeze mass all the way to its limit, or do we just have to get close enough?
