Most of the light in the universe comes from the stars. Without starlight,

Stars can be immensely bright, with some being many thousands of times brighter than the sun. 

The brightest known objects in the universe are called quasars, and they can be up to 100,000 times brighter than the entirety of the Milky Way galaxy

A quasar is composed of two beams of energy that move outwards in opposite directions

Hubble discovered that every quasar in the universe originates within the cores of massive, far away galaxies.

There are no known quasars in any of the closest galaxies to the Milky Way
