Pair Of Quasars Discovered

Pair Of Quasars Discovered:

The Hubble Space Telescope recently discovered a pair of quasars from the early universe.

  • A quasar is an extremely active and luminous type of active galactic nucleus (AGN).
  • An AGN is nothing more than a supermassive black hole that is active and feeding at the center of a galaxy.
  • The brightest quasars can outshine all of the stars in the galaxies in which they reside, which makes them visible even at distances of billions of light-years.
  • Quasars are thought to form in regions of the universe where the large-scale density of matter is much higher than average.
  • Most quasars have been found billions of light-years away.
  • Quasars emit energies of millions, billions, or even trillions of electron volts.
  • This energy exceeds the total of the light of all the stars within a galaxy.
