The Very Rare Hickson 91 Compact Galaxy Group

*****************

The largest of the three spirals (NGC 7214) in the Hickson 91 group is only 1.4 arcmin wide, but this is still a pleasing image. You can easily see the tidal tails caused by the galaxies’ gravitational interactions. At some distant time in the future the galaxies in this compact group will merge.

This is an RGB image.
