irregular galaxy in the constellation Chamaeleon
via Wikipedia infobox
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 galaxy has a short central bar, much like the Milky Way and very extended spiral arms. The central disk appears to be rotating in the opposite direction to the extended spiral arms.
