What are QUASARS?

Quasars are among of the brightest object in the universe, radiating more energy than entire galaxies. After speculating for years about a mysterious nature of quasars, astronomers now know that they are located at the heart of some galaxies. They draw their own energy from enormous black hole which has masses billions of times greater than that of our sun/ Like cosmic vacuum cleaner these gravitational monsters suck up matter fro their surrounding, releasing unimaginable quantities of energy in the process.
