Eduardo Banados, an astronomer from the Observatories of the Carnegie Institution, discovered a monstrous quasar located at 13 billion light-years away from Earth, which might help scientists learn more about the early Universe and how it formed. What puzzled the astronomer is that from the about 200 quasars found so far, “the peculiarity of this object is that it is extremely bright in radio waves,” as Banados stated.
A quasar, which is a stage in the evolution of galaxies, presents a supermassive black hole at its center and absorbs stellar matter while spits out high-energy particles. Usually, quasars emit radiations and light making them be among the brightest celestial objects in the visible Universe. However, the monstrous quasar Eduardo Banados was abnormally bright.
“To be honest, at the beginning I did not believe that this was coming from the quasar. It was too strong. I had never seen such a strong radio-emitter when the universe was so young,” said Eduardo Banados.

The scientist noticed that the radio waves emitted by the black hole at the core of the quasar dubbed as P352-15 are too powerful and very bright. That means the quasar itself is not a common one, but it’s a very dense one and is active since the early Universe.
After he pinpointed this unique quasar, Banados asked for help from the National Radio Astronomy Observatory (NRAO) in Socorro, New Mexico to employ the National Science Foundation’s Very Long Baseline Array (VLBA).
Helped by the VLBA reading, scientists could come up with a couple of theories, but one thing is sure, namely, as Emmanuel Momjian said, “this quasar may be the most distant object in which we could measure the speed of a jet” emitted by the black hole at the center of such a spectacular space object.
Although quasars are a combination of a supermassive black hole and the galaxy this one absorbs, only 10% of these celestial objects are very powerful radio waves emitters, such as the P352-15 monstrous quasar.
