Thanks for joining us for Black Hole Week 2023! We hope you had fun and learned something new about these weird balls of gravity. Hope you see you back at the event horizon for Black Hole Week 2024 (May 6-10). In the meantime, keep up with black hole news by following us on

Quick Facts
A black hole's "surface" is its event horizon. Inside this boundary, you'd have to go faster than light, the fastest thing in the universe, to escape the black hole's gravity.
While light can’t escape once it is past the event horizon, the areas around black holes can host some of the universe’s most spectacular light shows!
There are likely tens of millions of black holes dotted around the Milky Way, but so far we’ve only identified a few dozen. The ones we’ve found are typically paired with a star, interacting with it in a way that reveals the black hole’s presence.
