Galaxy Aarp 273 - Arp 273 is a group of interacting galaxies, lying 300 million light years away in the constellation Andromeda. It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in
NGC two galaxies that have been colliding for hundreds of millions of years. Just off to the lower right is the smaller galaxy, moving away. The larger galaxy used to be a spiral galaxy, now damaged. Gravity has distorted the shapes of the galaxies.
VV also known as Arp provides a textbook example of colliding galaxies seen in the early stages of their interaction. The edge-on galaxy near the top of the image is VV 340 North and the face-on galaxy at the bottom of the image is VV 340 South.
Galaxy Collision: This composite image of data from three different telescopes (x-ray, infrared, and optical) shows an ongoing collision between two galaxies, NGC 6872 and IC 4970 (the small galaxy to the left).

The Whirlpool Galaxy, the red spiral, and its companion galaxy, NG 5195 are 23 million light-years from Earth. The warm dust in red is a sign of active star formation probably triggered by a collision between the two galaxies.
