Scientists zero in on black hole

Cosmic Log - Scientists zero in on black hole: "Astronomers have taken an unprecedented look at the tumult surrounding a supermassive black hole, using a quintet of space telescopes. And they're finding out that it's a horribly messy eater. The black hole in question is at the center of the galaxy Markarian 509, which is nearly 500 million light-years away. Unlike the black hole at the center of our own Milky Way galaxy, Markarian 509's colossal black hole is sucking huge amounts of dust and gas into its gravitational maw. Its mass is 300 million times that of the sun, or roughly 75 times the mass of the Milky Way's central black hole."
