“We are looking at a very intense phase of galaxy evolution,” said Chao-Wei Tsai of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. “This dazzling light may be from the main growth spurt of the galaxy’s black hole.Source : The Astrophysical Journal.

NASA said 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,"

"The light is blocked by surrounding cocoons of dust. As the dust heats up, it radiates infrared light.
