Quasar

In General, almost all of the Galaxy there is a big black hole that is very powerful. Galaxy is also the core of galaxy. The core of the Galaxy is usually found in the center of a Galaxy, where black holes is super great. Because the black hole is thus generating energy for the core of the Galaxy.

Quasar active galactic nuclei are located far away and is the object of a very bright, very energetic and very strong. This object emits energy. When viewed in telescopes, quasars would seem like a point-like stars. But it turns out that point is not a star but a very bright Galaxy nuclei that are far away from us.

Quasars are powered by an enormous black hole at the Galactic Center, which digest the material around it and emits very large gravitational energy. It's always a black hole devouring the surrounding materials to get into her. Like giant eating anything around him.

When the black hole digest the material around it, the materials spinning faster and begin to heat up. All particles rubbing against each other so that release large amounts of light and x-ray radiation as well. Well when material is then in heartily by the black hole, then the North and South poles black holes would release energy that astronomers are known as cosmic jets. The energy is released very quickly and darting energy is very strong.

Quasar themselves do not always come from the merger of the Galaxy, because it is not the result of a combination of the two galaxies. Quasar could be in galactic black holes that could evoke a quasar in it. But when two galaxies merge, super black hole still in it will indeed form a quasar. Because the black hole is generating energy for active galactic nuclei.
