  • There ought to be more small satellite galaxies around the Milky Way than we have seen--and now, at last, they've been found. The main explanation is simple: they were there all along, we just missed them. Stacy Kim at Ohio State University in Columbus and her team pored through data from the Sloan Digital Sky Survey. They found that extrapolating from the number of galaxies in the survey area--about one third of the sky, thus far--we should be able to detect about 200 satellite dwarf galaxies
