* Extremely bright: Quasars are the most luminous objects in the universe, emitting more energy than entire galaxies.

* Star-like appearance: When viewed through telescopes, they appear point-like, similar to stars.

* Distant: Quasars are found billions of light-years away.

Here's how quasars work:

Quasars are powered by supermassive black holes at the centers of galaxies. As material falls into the black hole, it heats up and emits intense radiation across the electromagnetic spectrum.
