Photo: "Rogue" Dwarf Shines New Light on Tiny Galaxies



There's a new rogue dwarf joining our party—although it's not one you'd be likely to find in World of Warcraft.

Andromeda 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.
