Where is the Central Supermassive Black Hole?

"Expecting to find a black hole in every galaxy is sort of like expecting to find a pit inside a peach," explains astronomer Tod Lauer of the National Optical Astronomy Observatory in Tucson. "With this Hubble observation, we cut into the biggest peach and we can't find the pit. We don't know for sure that the black hole is not there, but Hubble shows that there's no concentration of stars in the core." MORE
