Scientists discovered the oldest known source of a radio signal so far, and these radio rays that reached the earth and discovered by scientists took 13 billion years to reach the earth, meaning that the signal that scientists captured goes back to the time when the age of the universe was 730 million years. Knowing that its source is quasar.
Many quasars have been discovered in the past, but the quasar is the furthest source detected so far.
Quasars are one of the brightest cosmic bodies, and are usually found in the centers of some galaxies, and they derive their energy from a supermassive black hole. When the black hole consumes the surrounding gas, it releases bursts of energy capable of crossing the universe to reach the Earth at some point, and scientists have been able to The capture of these rays is due to the radio activity of this quasar, which is not unique to all quasars, as only 10% of quasars are able to emit radio rays.
Despite the discovery of many cosmic bodies dating back to the age of the early universe, the detection of objects that emit radio rays is among the most difficult discoveries so far.
The P172 + 18 quasar derives its energy from a supermassive black hole, which is very virulent, and its mass is 300 million times greater than the mass of our sun, and it drains surrounding materials at a tremendous speed, and it is one of the fastest-growing objects observed so far.
Scientists were able to reveal the details of this quasar using the Magellan telescope located at the La Campanas Observatory in Chile, and there is more research on the accelerated growth of this black hole and the discovered quasar that is made using a lot of equipment, including the very large telescope in the European Southern Observatory.
The record in distance from Earth recorded by this quasar may not hold, as with more research, cosmic bodies will be found further away in the universe.
