NGC 5395 and 5394 , also known as Arp 84, are two interacting galaxies in the constellation Canes Venatici. The larger, NGC 5395, is at a distance 165 million light-years and NGC 5394 is 162 million light-years away. NGC 5394 is thought to have cart wheeled through NGC 5395, instead of a grazing encounter.

The larger elliptical galaxy, to the upper left of NGC 5394, is IC 4356. At a distance of about 675 million light-years, IC 4356 is a member of the Virgo I galaxy group.

Arp 84 is also known as the Heron Galaxy. It takes little imagination to see a blue heron's body, complete with neck, head and a beak reaching out to a nearby fish. Also seen in the image, are hundreds of background galaxies... as faint as magnitude 23.2.
