Rare Quartet of Quasars 'Lyman-a' Spread over a Distance of 700,000 Light Years Apart

Four quasars were discovered in the nebula, known as the Lyman-a, for the first time in the cosmic history. Quasars are nothing but very bright objects which are present in very close proximity with each other, and are found to be really rare.

This study was being carried out at the Max Planck Institute for Astronomy in Germany and was led under the guidance of Joseph Hennawi. This group of scientists were studying 29 quasars of the nebula. During the research phase, they suddenly discovered this rare quartet-quasar.

Hennawi revealed that finding multiple quasars system is in itself a big achievement as quasars are already so rare. He further said that the normal distance between two quasars is around 100 million light years. The recently discovered quasars in Lyman-a nebula are within 700,000 light years from each other. Thus, the probability of this event is about 1 in 10 million, states CS Monitor.

Hennawi also explained the algorithm of the quasars' formation. He said that the presence of a black hole at the center of every galaxy attracts the materials which revolve around it till its rim, making these celestial materials to travel equivalent to the speed of light. In case, the attraction is very strong, then these materials enter the quasar phase in the universe.

After this stage, this blob of celestial object gains so much energy that it leaves its parent galaxy and becomes the brightest object in the universe. According to Hennawi, the lives of these quasars is very brief, lasting somewhere around 10 million to 100 million years.

Almost 500,000 quasars were found till date but only few of them were in a binary state, let alone in a quartet, as per reports by Omni Feed.

The sighting of this quadruple-quasar system has been done for the first time in the entire universe. This discovery has galvanized all the astronomers and scientists as they are super excited about this discovery.
