'Red and dead' galaxies surprise astronomers

Maggie McKee reports for NewScientist: “The corpses of three “dead” galaxies - which to the surprise of astronomers stopped forming stars long ago - have been identified by the Spitzer Space Telescope during a survey of the distant, early universe. The find bolsters a theory that colossal black holes can starve galaxies of the gas needed to create new stars.”
