World – NASA, the US aerospace agency said on Thursday (21) the discovery of a remote galaxy has a brightness of more than 300 trillion suns. The galaxy belongs to a new class of celestial bodies recently discovered by the infrared telescope WISE- Wide-field Infrared Survey Explorer, the “extremely luminous infrared galaxies”.
The galaxy, cataloged as WISE J224607.57-052635.0, may have a black hole at its center. According to NASA, this is rare in a distant galaxy like this.
The `supermassivos` holes attract gas and matter to an accretion disk around it, about to heat up to temperatures of millions of degrees and cause release visible light, ultraviolet and X-rays. The light is blocked by “cocoons” dust, which, when warm, emanating infrared radiation.
According to the US agency, the light from the galaxy traveled 12.5 thousand million years to reach the current time, so astronomers see the body as it was in the past. The black hole would have a billion times the mass of the Sun when the universe was one-tenth of its present age, about 14 billion years.
“We are observing a lot of intense phase of galaxy evolution,” said Chao-Wei Tsai, NASA, and lead author of the study, which is published on Friday in The Astrophysical Journal.
As the black hole in question has become so gigantic remains an unknown to the authors of the research, who believe that “dazzling light” the galaxy can be derived from the action of this hole.
The study reports 20 new “extremely luminous infrared galaxies”, including the brightest galaxy detected so far. These galaxies were found previously due to its distance and because the dust makes its visible light into infrared radiation, not visible.
