The four prominent galaxies seen in this intriguing image are one such group, Hickson 44, about 100 million light-years distant toward the constellation Leo.

The two spiral galaxies in the center of the image are edge-on NGC 3190 with its distinctive, warped dust lanes, and S-shaped NGC 3187.

Along with the bright elliptical, NGC 3193 at the bottom left, they are also known as Arp 316. The spiral in the upper right corner is NGC 3185, the 4th member of the Hickson group.
