A quasar is an astronomical entity that emits a very high levels of electromagnetic radiation. A single quasar can give off more energy than 100 normal galaxies. It believed that what we are really seeing is the interaction of matter with massive black hole at the center of galaxy.

A quasar is an astronomical entity that emits a very high levels of electromagnetic radiation. A single quasar can give off more energy than 100 normal galaxies. I think Quasar may stand for quasi-stellar-objects or “quasars”. But what is it? Why does it emit such a bright light?

Well a quasar is created by matter interacting with the supermassive black holes at the heart of most known galaxies. The matter that collects close to the black hole forms an accretion disk, with gravitational influences that cause super-heating of the matter up to millions of degrees. The resulting energy is released in the form of jets of radiation that extend millions of light years from the supermassive black hole.
