NGC 3718, at right, is an unusual warped spiral galaxy in Ursa Major. Also known as Arp 214 from Harlton Arp's Atlas of Peculiar Galaxies, it is also classified as a galaxy with an active nuclei powered by a giant black hole. NGC 3718 shines with an apparent magnitude of 11.6 and has an apparent size of 8 x 4 arc minutes. It lies about 52 million light years away. NGC 3718 is thought to be interacting with barred spiral galaxy NGC 3729 (left), which is located about 150,000 light years from NGC 3718 in space, and some 11.5 arc minutes away from our perspective. The interaction may be causing the warping of NGC 3718, but it is also possible that the disturbed nature of the galaxy is caused by an act of galactic cannibalism where NGC 3718 consumed another galaxy. This may also account the the prominent dust lane in NGC 3718, which is second only to the dust lane found in NGC 5128 (Centaurus A) which harbors a gigantic black hole itself. Hickson 56 (Arp 322), a group of 5 galaxies (from left: PGC 35631, PGC 35620, the interacting pair PGC 35618 and PGC 35615, PGC 35609) is to the south (below) NGC 3718, and lies more than 400 million light years away.
