This group of four galaxies is around 220 million light years away.
The collection of spiral galaxies on the left side of the image include:
(from top to bottom) NGC 542, NGC 536 and NGC 531. The warped arms of
the latter two galaxies strongly suggests they are interacting with
one another. NGC 529 on the right side of the image is a bright lenticular
galaxy. This galaxy probably used to be a spiral like its neighbors, but
either due to gravitational interactions or a lack of material to form
more stars has relaxed to this smooth almost elliptical (but not quite)
