ARP 273 -3- Hubble
ARP 273, files downloaded from Hubble Legacy Harchive and processed by me with Pixinsight and Photoshop, filters used: f390w, f475x and f600lp. Credit: Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA). Arp 273 (APG 273) is a pair of interacting galaxies located in the direction of the constellation Andromeda at a distance of 345 million light-years from Earth.
It is catalogued in the Atlas of Peculiar Galaxies compiled by Halton Arp in 1966. The pair is formed by the interaction of the spiral galaxy UGC 1810 which appears face-on and the five times smaller spiral galaxy UGC 1813 which appears almost in profile (edge-on). The latter shows the hallmarks of active star formation in the galactic core and is hypothesized to have already crossed the larger galaxy in the past. At the end of one of UGC 1810's spiral arms, a third small galaxy can be seen.
On January 28, 1962, a type II supernova was detected in the galaxy UGC 1810 cataloged as SN 1962R.
Arp 273 is part of the galaxy cluster Abell 347, itself a component of the Perseus-Pisces Supercluster (SCl 40).
