Shining so brightly that they eclipse the ancient galaxies that contain them, quasars are distant objects powered by black holes a billion times. Many astronomers believe that quasars are the most distant objects yet detected in the universe. Quasars give off enormous amounts of energy - they can be a. Studies showed that these quasars lie at the hearts of distant galaxies to dim to be seen by themselves. It was also discovered that the region producing light.

Quasars also provide some clues as to the end of the Big Bang 's reionization. This energy exceeds the total of the light of all the stars within a galaxy. The word quasar is short for "quasi-stellar radio source". When two quasars are so nearly in the same direction as seen from Earth that they appear to be a single quasar but may be separated by the use of telescopes, they are referred to as a "double quasar", such as the Twin Quasar. The matter accreting onto the black hole is unlikely to fall directly in, but will have some angular momentum around the black hole that will cause the matter to collect into an accretion disc.

Many astronomers believe that quasars are the most distant objects yet detected in the universe. In other projects Wikimedia Commons. A quasar gradually attracts this gas and sometimes other stars or or even small galaxies with their superstrong gravity. The emission of large amounts of power from a small region requires a power source far more efficient than the nuclear fusion that powers stars. Perhaps one of the most perplexing mysteries in current astrophysics is the science behind Quasars. Like us on Facebook. Most quasars, with the exception of 3C whose average apparent magnitude is But was it really? Since they have the largest red shift of any known object in the cosmos due to the effect of the expansion of the universe, astronomers are able to observe their red shift to measure their speed and distance.
