Hubble observes an oddly organized satellite galaxy

Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way's closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appears devoid of new star formation and younger stars. In fact, Andromeda III seems to be only about 3 billion years younger than the majority of globular clusters―dense knots of stars thought to have been mostly born at the same time, which contain some of the oldest stars known in the universe.
