Why Do Black Holes Glow?

Imagine a black hole as like a really hungry vacuum cleaner. When it eats something, especially stars or gas clouds, it gets so excited that it starts glowing bright, like when you drop a cookie into a dog's mouth and they wag their tail and bark at the light! This glow is called accretion, and it’s what happens when stuff gets squished really fast near the black hole.
