Astronomers at the National Aeronautics and Space Administration (NASA) have discovered a distant galaxy. According to the United States space agency, the newly discovered galaxy is the brightest galaxy in the Universe so far. The galaxy shines as bright as about 300 trillion suns.

In a press release, the space agency said that the galaxy has been named 'WISE J224607.57-052635.0' and is a part of a new class of object. To discover the galaxy, NASA astronomers used data from its Wide-field Infrared Survey Explorer (WISE), an infrared-wavelength astronomical space telescope.

NASA said that the galaxy shines due to the infrared light that comes from a huge black hole. Those black holes draw gas and matter into a disk around them. They heat the disk to a temperature of millions of degrees and blast out visible, high-energy and X-ray light. That light is blocked by the cocoons of dust that surrounds it, NASA stated.

According to the space agency, it is not found that how black hole reached a huge size. In a paper in Astrophysical Journal, NASA said that there could be a number of theories. Scientists said that there are possibilities that it was born big.

Lead author of the NASA report, Chao-Wei Tsai, said, "Another way for a black hole to grow this big is for it to have gone on a sustained binge, consuming food faster than typically thought possible. This can happen if the black hole isn't spinning that fast".

According to NASA, the light took more than 12 billion light years to reach the place where astronomers saw it, which means that the picture of the galaxy is ancient. The scientists said that the discovery is rare and surprising which could reveal interesting things about Universe.
