A quasar is a starlike object in space that may emit energy, light, and radio waves.

In the vastness of the universe, there are many bodies such as planets, moons, asteroids, and suns. Another type of object is the quasar. Quasars are a lot like suns, though much smaller. Quasars have large redshifts, which means the light from the quasar increases in frequency, moving to the red part of the light spectrum. Quasars are powerful and usually produce a lot of radiation. Don't mess with a quasar!
