    Astronomers are using Hubble to look at Comet Holmes, a strange comet that brightened this October to nearly a million times in less than 24 hours. Comet Holmes is the only comet ever seen to brighten so strangely and dramatically. The brightening was first witnessed 115 years ago ? astronomers will be able to get a better look now that the comet is performing under Hubble's gaze. An elliptical galaxy with a supermassive black hole in its center looks like it underwent a collision in the distant past. The collision is fueling the black hole, feeding it meals of stars, gas and dust.
