Black holes may look like big dark spots in space, but they can shine brightly because of the accretion disk, a ring of hot, glowing matter that swirls around them. When this matter gets pulled into the black hole, it releases energy that lights up the universe, just like fireworks exploding from a party.
Examples
- Accretion disks can glow so brightly that astronomers can see them from millions of light-years away.
- When stars fall into a black hole, they sometimes explode in a brilliant flash of light.
