Astronomers spot black hole 'burping' twice in 100,000 years
Using data from NASA's Chandra X-ray Observatory, astronomers have spotted a supermassive black hole consuming gas clouds and "burping" on two occasions one lakh years apart. Chandra detected a bright, point-like source of X-ray emission from galaxy J1354 signalling a black hole. The X-rays are produced as gases get heated under gravitational forces and are later expelled as high-energy particles.
