Photo: "Rogue" Dwarf Shines New Light on Tiny GalaxiesAndromeda XIV is a recently discovered dwarf galaxy on the outskirts of galaxy M31 (seen above), which is part of the so-called galactic local group that includes our Milky Way. The odd dwarf is moving too fast to fit into standard models of how these tiny, faint galaxies take shape, a new study says, which suggests that it might have formed in isolation and is just now entering our cosmic neighborhood.
