Most distant black hole in early universe

     Scientists have discovered a supermassive black hole ; the farthest known black hole ever.Its matter-eating beast is about 8000000000 (8 x 10^9) times the mass of the sun, which is extremely large for its young age. Researchers have published their findings in the "journal of Nature" This black hole grew very fast then expected by the scientists, it started to become black hole within 690 million years after the great Big-Bang challenging the theories of black hole formation.


     Scientists used the data from WISE ( Wide-field Infrared Survey Explorer) with ground based surveys to study this black hole. It was also observed by Carnegie observatory and Magellan Telescopes in Chile. Carnegie astronomer Eduardo Banados led his full efforts to identify the object out of million objects through the data from WISE. It had been found that, to follow the black hole with Magellan Telescope will be better than WISE.


     The formation of black hole in s short age is a mystery. Scientist predict that for a large black hole in the early stage of universe, there must be some special condition to allow the rapid growth of this black hole. It may be the result of a quasar. 


    The universe started to began after 400,000 years after the big-bang, the particles and masses from big-bang spread apart in the universe. These particles were cooled and turned into hydrogen gas, but still it prevailed dark universe without any source of light. After that the gases in the space get ionised so that the light can travel. Thus the universe become transparent to light. Scientists predict that whole sky contains 20 to 100 quasars as bright and distant. 

Collaborative Mission:

     A mission called European Space Agency's Euclid Mission and NASA's Wide-field Infrared Survey Telescope are deeply involved in finding the distant objects in the sky. We will have several facilities and technologies to predict exciting discoveries in the early universe in coming up years as stated by Stern, NASA.
