Huge black hole blasts out 'double burp'Astronomers have caught a massive black hole letting out a "double burp" after binging on hot gas. The burp itself consists of a stream of high-energy particles that is kicked back from the black hole. In the meantime, it had expanded 30,000 light-years away from the black hole itself. She said the black hole was going through a cycle of feasting, burping and napping, before starting over. The researchers think the black hole erupted twice because it consumed two separate meals.
