Hubble image of Arp 219, also known as UGC 2812.
Arp 219 appears in several catalogs of ring galaxies. The ring, made of tidal tails of material that wrap around the galaxy, was likely formed through interactions with a companion galaxy.
In this image, the luminosity comes from Hubble ACS/WFC observations, and color comes from PanSTARRS.
