supermassive black hole
The first image of a black hole shows the supermassive black hole at the center of the galaxy M87.
  • Scientists have obtained the first ever proof that black holes can lose energy.
  • They've long believed that magnetic fields could suck energy out of black holes but didn't have proof — until now.
  • The M87 supermassive black hole is emitting energy like "million-light-year-long Jedi lightsabers," the co-author of a new study said.

Scientists have long believed that black holes, which generally swallow up everything around them, can also lose energy.

But they didn't have proof — until now.

A new study published this month found that the M87 supermassive black hole is emitting huge amounts of energy thanks to its magnetic field.
