Astronomers are about to see a black hole gobble up a gas cloud: Gas clouds fate illuminates growth of supermassive black holes G2, a doomed gas cloud, is edging closer to Sgr A*, the hungry supermassive black hole at the Milky Ways center. The closest approach between the two is predicted to occur any day now. Astrophysicists have been watching closely, and the data do not show enhanced emission in the X-rays. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action. This work is fascinating because it will teach us about the growth and feeding of supermassive black holes....we arent sure in detail how they get their mass. Do they grow rapidly when they are young, like our kids do, or do they grow in fits and starts, whenever fuel becomes available? sciencedaily/releases/2014/04/140404085807.htm
