Scientists discovers the Farthest Known Black-Hole Ever

Scientists have discovered the relic object from the early universe; NASA declared it as the farthest known super-massive black hole. According to NASA, the gargantuan black hole is 800 million times the mass of our Sun and is enormous for its young age. Study co-author Daniel Stern of NASA’s Jet Propulsion Laboratory located in Pasadena, California claimed that it challenges the theory about the formation of black hole.

This black hole grew larger than anticipated in only 690 million years after the Big Bang. Some astronomers hypothesized that due to special condition the black hole might have took the rapid growth. Scientist named this massive material underlying in the center of galaxy as a quasar. The co-author Bram Venamans of the Max Planck Institute for Astronomy in Germany defines the Quasar as the brightest and most distant known celestial objects that are crucial to understanding the early universe. Study of quasar is essential, as it comes from the time when universe was emerging from dark ages.

The discovery will help for information about universe when it was only 5 percent of the current age. The period when the universe began in a hot soup of particles that spread apart is called Inflation. After the Big Bang and about 400, 000 years, these particles cooled and coalesced into neutral hydrogen gas. The universe stayed without luminous source, until gravity condensed matter into the first stars and galaxies. The study of quasar will provide additional information before the universe became reionized. According to Banados, “It was the universe’s last major transition and one of the current frontiers of the astrophysics”. Scientists determined the distance of quasar by redshift, which is a measurement to determine the wavelength of the light stretched by the expansion of the universe before reaching Earth”. The higher the redshift, the greater the distance and astronomers are evaluating the time when they observe the object.

The newly uncovered quasar has a red shift of 7.54 that is based on the detection of ionized carbon emissions from the galaxy that hosts the massive black home. It means it took 13 billion years for the light from the quasar to reach us. Scientist speculates sky contains between 20 and 100 quasars as bright as distant as this quasar. NASA is looking forward from different other agencies, which they have been working to find the distant object. Stern said” The sensitive facilities and next generation tech we can expect many exciting discoveries about the early universe in coming days”.
