Quasar

A quasar is an incredibly bright light which occures when gas near a supermassive black hole goes into the black hole at very high speed. When the gas gets close to the black hole, the gas heats up because of friction. Therefore, the gas glows very brightly, and this light is visible on the other side of the Universe. It is often brighter than the whole galaxy that quasar is in.

Galactic Astronomers now think that when a galaxy has a quasar, the quasar changes the galaxy. A quasar can also be the beggining of a Galaxy and the object which creates the galactic core. Every galaxy begins as an elliptical galaxy, and gas and dust gathers in the centre. Eventually this gas ignites to form the equivalent of a galaxy-sized star. This gigantic star lives only for a few hundred years before it's core collapses into a giant black hole, which then consumes the rest of the Gas, resulting in a quasar. Quasars run the lives of galaxies. First, a galaxy is changed from an irregular galaxy to a spiral galaxy, and then from a spiral into an elliptical galaxy. Every time a quasar occors, it significantly changes the Galaxy. The Skyriver Galaxy also began as a quasar, and had since experienced a second.
