How do quasars produce so much light?
Quick Answer
A quasar is powered by a supermassive black hole feeding on gas and dust. As the material heats up while falling in, it can outshine an entire galaxy.
The Full Story
Quasars are among the brightest objects in the universe because matter swirls into a supermassive black hole and forms a very hot accretion disk. Friction and magnetic effects heat the gas to extreme temperatures, causing it to emit huge amounts of light. Some quasars are visible across billions of light-years. They were first identified in the 1960s when astronomers realized these point-like radio sources were incredibly distant and energetic.
