I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.

UGC 4653 known as Arp 195, is a trio of interacting galaxies located 763 million light-years away from the solar system in the Lynx constellation.[1] The galaxies are being distorted through gravitational interactions with each other.[2]

This image was captured by the Hubble Space Telescope.[2] The galaxies make up the 195th object in the Atlas of Peculiar Galaxies which was created by Halton Arp.[3] They fall into the category of galaxies with material ejected from nuclei.[4]

UGC 4653 has active nuclear regions which produce infrared (IR) emissions.[5] These appear to be more like AGNs than HII regions.[5]

Supernova

Type Ia supernova, SN 2008bv[6] was discovered in UGC 4653 with a magnitude of 18.3.[7] It was located 1".7 east and 3".9 south of the nucleus.[8]
