NGC 2915 is a blue dwarf galaxy located 12 million light-years away in the southern constellation Chamaeleon, right on the edge of the Local Group. The optical galaxy corresponds to the core of a much larger spiral galaxy traced by radio observation of neutral hydrogen.
The reason for the spiral arms and majority of the galaxy's disk to be still neutral hydrogen (as opposed to have formed stars) is not well-understood but is thought to be related to the galaxy's isolation, in that it has no nearby satellite galaxies and no nearby major galaxies to force star formation.
