Located in the unspoiled wilderness universe, with a distance of 12.5 billion light years from Earth, there is a very bright galaxies. Even being the most sparkling in the universe - at least until now.
Its sparkle brightly more over 300 trillion than the Sun. The galaxy is called WISE J224607.57-052635.0. The existence of these galaxies are known by means of NASA's Wide-field Infrared Survey Explorer (WISE) satellites.

NASA believes the discovery will change our view of the universe so far. "We are witnessing a phase of the galaxy evolution that is very intense," says NASA in a statement as quoted by News.com.au.
The astronomers team of NASA suspect, a giant black hole is in the middle of the galaxy responsible for the strange phenomenon, the brilliance of the galaxy.
"The giant black hole was pulling gas and materials into the disk around them. As a result, the disc heats up to temperatures of millions of degrees," according to NASA.

The material is sucked into the black hole spiral, may be heated in an extraordinary way, and then release large amounts of visible light - ultraviolet and X-ray wavelengths. The light is blocked by cloud of dust in the vicinity. When the dust is heated, then emits infrared rays.
Although the existence of a black hole at the galactic core is not new, however, such findings - in the wilds of the cosmos is rare. Because the light from galaxies where black holes are within 12.5 billion light years, astronomers seemed to see the object as if they were in the past.
"The black hole size is billions of times the mass of our Sun, when the new universe there is a tenth of its current age is 13.8 billion years," NASA said. Currently NASA is trying to determine the mass of the black hole at the center.
"Knowing that these objects would reveal their history, as well as other galaxies, it is part of an important and complicated associated universe." The findings are explored in detail in The Astrophysical Journal in May 2015.
The question is, why a black hole could be as big and move fast? The study authors suspect, it may indeed be a black hole of that size at birth.
"Like a big elephant," said Peter Eisenhardt one of the authors of the study from the Jet Propulsion Laboratory (JPL) of NASA in Pasadena, California, USA, as quoted from SPACE.com. "He came from a baby elephant."
However, there is another explanation. "The other way how a black hole grow by it is to keep 'partying', swallow matter and gas around it, faster than what is expected," said Chao-Wei Tsai, the study leader who is also from JPL.
WISE that find the WISE J224607.57-052635.0 in between 19 'extremely luminous infrared galaxies' (ELIRGs). Strong light from the ELIRGs core heats around clouds of dust, which is then emitted infrared radiation which can then be detected by WISE. *** [EKA | FROM VARIOUS SOURCES | NEWS.COM.AU | SPACE.COM]
