Added 1 new A* page:This BBC article talks about NASA's Chandra X-Ray space telescope finding evidence for a supermassive black hole at the center of a galaxy 800 million light years away having emitted two clouds of gas, 100,000 years apart, which would seem to confirm the theory that huge black holes can go through feeding cycles, where the intense radiation and high-energy particles thrown off during such a black hole's active period serve to push other material around the hole away, resulting in a quiet period in which the hole has nothing to "eat"—until material again drifts close enough for the hole to feed, and the cycle begins again. Sgr A*, the supermassive black hole at the center of our own Milky Way galaxy, is, in this theory, in one of those quiet periods between feasts.
