Image Description:

This is the not-so-cleverly named NGC 5044 Galaxy Group in the constellation of Virgo, significantly South and a bit East of Markarian's Chain, also in Virgo. The large spiral in the lower left is NGC 5054, which may or may not be associated with the rest of the galaxies in this group. The image above is a 50% scaled version of the original, cropped for display on the web. The full size image is also available. North is up.
