Early this year, astronomers trying to understand quasars--objects that shine with the brilliance of millions of stars from the far edges of the universe--got a shock. Theorists assumed that each of these beacons is powered by a giant black hole sucking in material from a surrounding galaxy. But when the Hubble Space Telescope provided the first clear look at quasars, the host galaxies seemed to be missing. Now a reanalysis of the same images suggests that the galaxies were there all along.
