Quasars are one of the main mysteries of space. They have been seen as far as seven billion light years away. Most of them are now on the edge of the galaxy. It has giant spikes of light on the edges that mean that it is in a disrupted galazy or in a colliding or merging galaxy.

     One theory for quasars is that they are giant black holes eating up dust, gas, and stars. If this was true, it would be destroying galaxies. The discoverer of Quasar was named Schmidt. He named it "Quasi-stellar" (starlike).

     Just a few years later a man named Hang-Yee Chiu changed the name to "Quasar."

     One quasar was found switching to the red area of the nebula. Another was found moving at 1.5 billion light years away from Earth. That’s when the race began to find faster moving quasars. Another was found moving at 81.2 percent the speed of light years. Even faster ones were found until one was found moving at 90% the speed of light!

     Quasars give off the same amount of energy as a regular star.

     They give off a giant amount of infrared radiation. Another theory is that quasars are leftovers from the "Big Bang." That theory is the one that is most believed. They may be the nuclei of ancient galaxies or be a galaxy being born.
