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 1966. Read more On the 28th January 1962, a Type II supernova catalogued as SN 1962R was discovered in the galaxy UGC 1810. Arp 273 is part of the Abell 347 cluster of galaxies, which in turn is part of the Perseus-Pisces Supercluster (SCl 40). __________________

A galactic rose highlights Hubble's 21st anniversary In celebration of the 21st anniversary of the Hubble Space Telescope's deployment into space, astronomers pointed Hubble at an especially photogenic group of interacting galaxies called Arp 273. This image, taken by the NASA/ESA Hubble Space Telescope, shows a group of interacting galaxies called Arp 273. The larger of the spiral galaxies, known as UGC 1810, has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The swathe of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light.
