What is a supermassive black hole?

Back

A supermassive black hole is a black hole with a mass that is millions to billions times that of the Sun, often found at the center of galaxies.

Front

How do quasars differ from regular galaxies?

Back

Quasars are extremely luminous and are powered by supermassive black holes, while regular galaxies do not exhibit such extreme brightness.
