Scientists Discover Most Brightest Galaxy In The Universe

             

The United State Space Agency (NASA) said in Washington yesterday that, a new galaxy 12.5 billion light-years from Earth has been discovered and it is the most luminous one known in the universe, blazing more brightly than 300 trillion suns.

The NASA Wide-field Infrared Survey Explorer (WISE) telescope discovered the remote galaxy that shines with the light of more than 300 trillion suns, making it the most luminous galaxy ever found.

It said the galaxy, known as “WISE J224607.57-052635.0’’, belongs to a recently discovered new class of objects called extremely luminous infrared galaxies.

NASA said its dazzling light may be due to a behemoth black hole at its belly.
The space agency explained in a statement that “Supermassive black holes draw gas and matter into a disk around them, heating the disk to roaring temperatures of millions of degrees and blasting out high-energy, visible, ultraviolet, and X-ray light.
It said the light, however, was absorbed by surrounding cocoons of dust, which prevents the agency from seeing the galaxy with optical telescopes.
“When the dust heats up, it radiates infrared light, which is only now detected by the WISE telescope.
NASA said because light from the galaxy hosting the black hole has traveled 12.5 billion years to reach us, astronomers are seeing the object as it was in the distant past.

It said just like the most luminous galaxy found to date, the galaxies were not found earlier because of their distance, and because dust converts their powerful visible light into an incredible outpouring of infrared light.
