That black hole photo: How event horizons bend time, space, and light

The recent photo of a black hole is something extraordinary. Here's why.

  • Black holes are usually surrounded by disks of very, very bright, very hot material. And that's how we find them.
  • Black holes themselves give off no radiation at all. Any light gets absorbed into the black hole — all forms of light, from gamma rays to radio waves.
  • A black hole's gravity is so strong it actually bends space itself. What does this mean? There's no way to get out of the black hole — out of the event horizon — because space and time themselves are bent into the black hole.
