Quasars are the most luminous celestial objects in the universe and all over across the entire electromagnetic spectrum. Quasars are typically more than 100 times brighter than the galaxies which host them. In reality they are powered by supermassive black holes a billion times as massive as our sun. The light we see from quasars comes from a disk of gas and stars, which surrounds the black hole called an accretion disk. Intense heat and light is emitted from this accretion disk, caused mainly by friction produced from the swirling around. Most quasars have been found billions of light-years away. Galaxies like the Milky Way may once have hosted a quasar that has long been silent. The most distant known quasar is ULAS J1342+0928. The Huge-LQG {Large Quasar Group} (U1.27)73 remains the largest structure known in the observable universe, as of 2013.
