Massive black holes stop the creation of new stars: "Just months ago, NASA's Chandra X-ray Observatory discovered record 20 million mph (32 million km/h) winds nearby a supermassive black hole. Now astronomers working on ESA's Herschel Space Observatory are suggesting that such incredibly strong winds - whose speed depends on the size of the black hole - are preventing the gas and dust in galaxies from forming new stars, explaining the link between the size of a black hole and the rate at which new stars are formed."
