Twinkling heart of the Milky Way spotted. Researchers hope more info on supermassive black hole now

India TV News  

Twinkling heart of the Milky Way spotted. Researchers hope more info on supermassive black hole now For the first time, astronomers have found quasi-periodic flickers in milimeter-waves from the center of the Milky way galaxy, Sagittatrius A*. The team interpreted these blinks to be due to the rotation of radio spots circling the supermassive black hole with an orbit radius smaller than that of Mercury. According to the paper published in Astrophysical Journal Letters, astronomers presume that a supermassive black hole with a mass of 4 million suns is located at the center of Sgr A*. “This emission could be related with some exotic phenomena occurring at the very vicinity of the supermassive black hole,” says Tomoharu Oka, a professor at Keio University.
