Four quasars were spotted by the scientists in a distinct region of the universe. To find a single quasar in the universe is very difficult, thus this is a rare and exceptional discovery.

Quasar is a chapter of galactic evolution. Its life is extremely short. A quasar shines between 10 million to 100 million years in the 10-billion-year lifetime of a galaxy.  This causes the objects extremely exceptional and difficult to find. Discovering four so close together came as a shock.

However, that is exactly what they have found.

“This was extremely surprising, as we knew that quasars are very rare objects, and it should be extremely unlikely to find four of them so close together,” writes  wrote of the Max Planck Institute for Astronomy.

This is a new part of space they are exploring, and it is 10 billion light years away from our planet.

Xavier Prochaska from University of California (Santa Cruz) professor mentions, “There are several hundred times more galaxies in this region than you would expect to see at these distances.”

Hennawi added, “It may be that quasar episodes are more likely to be triggered in such an unusual environment, which is rich in both gas and galaxies;” conditions that had been regarded to be mutually exclusive.


He added that the next is to try to look for more of these giant emission clouds, something that the new results suggest is easier than previously thought.

    Quasars are eternal, they alternate very long phases of activity and sleep.
    The quarted of quasars may belong to different Big Bangs.
    The alignments of quasars crediting thoughtful geometry of this universe.
