What are quasars?</h3>
A quasar is a massive and extremely distant celestial object that emits extremely large amounts of energy and typically appears as a star in a telescope. It has been proposed that quasars contain massive black holes and may represent an evolutionary stage for some galaxies.
Quasars are extremely bright celestial objects. Quasar is an abbreviation for quasi-stellar radio source. A quasar is a very bright active galactic nucleus (AGN) powered by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses and surrounded by a gaseous accretion disc.
Quasars have enormous radiant energy. The most powerful quasars have luminosities that are thousands of times that of a galaxy like the Milky Way.
