NGC 1156 is a dwarf irregular galaxy in the Aries constellation of the type ibm. It is considered a Magellanic-type irregular. The galaxy has a larger than average core, and contains zones of contra-rotating gas. The counter-rotation is thought to be the result of tidal interactions with another gas rich galaxy some time in the past.
The AGES survey has discovered a candidate dark galaxy close to NGC 1156, one of only a few so far found.
It has a H II nucleus.[2]
