Amazing Facts

Facts about Quasars






  1.     Quasars are the most intense sources of light in the
    Universe. Although no bigger than the Solar System, they glow
    with the brightness of 100 galaxies.

  2.     Quasars are the most distant known objects in the
    Universe. Even the nearest is billions of light-years away.

  3.     The most distant quasar is on the very edges of the known
    Universe, 12 billion light-years away.

  4.     Some quasars are so far away that we see them as they were
    when the Universe was still in its infancy — 20 percent of its
    current age.

  5.     Quasar is short for Quasi-Stellar (star-like) Radio
    Object. This comes from the fact that the first quasars were
    detected by the strong radio signals they give out and also
    because quasars are so small and bright that at first people
    thought they looked like stars.

  6.     Only one of the 200 quasars now known actually beams out
    radio signals, so the term Quasi-Stellar Radio Object is in fact
    misleading!

  7.     The brightest quasar is 3C 273, two billion light-years
    away.

  8.     Quasars are at the heart of galaxies called ‘active
    galaxies’.

  9.     Quasars may get their energy from a black hole at their
    core, which draws in matter

  10.     The black hole in a quasar may pull in matter ferociously.

  11.     The Hubble space telescope’s clear view of space has given
    the best-ever with the same mass as 100 million Suns.
