NEW YORK: Scientists have spotted four different quasars in different regions in the space. This is a rare discovery as it is a very difficult to spot even a single quasar in the space. Finding the quadrapular quasar has been surprising and an exceptional spotting for the scientists. Scientists say that similar spotting similar quasars would be possible in the near future.
What really is a quadruple quasar?
Well, first, a quasar is a phase of galactic evolution; and it is very brief. While finding one quasar is easy, finding two in one place is a little rarer. Finding three is highly improbable; but finding four should be impossible.
Yet, 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 Joseph Hennawi wrote of the Max Planck Institute for Astronomy.
But this is a new part of space they are exploring. And the good news is that many discoveries are being made in this region of space, 10 billion light years away from our planet.
For example, University of California (Santa Cruz) professor Xavier Prochaska comments, “There are several hundred times more galaxies in this region than you would expect to see at these distances.”
Hennawi goes on to say, “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.
Furthermore, he explains “Current models of how structure forms in the universe would never predict that there would be so much cool, dense gas around. Instead, those models predict that the gas in such a massive object should be 1,000 times hotter and 1,000 times less dense.”
