UGC 8335 (Arp 238) is a pair of strongly interacting spiral galaxies. They have been distorted by extreme tidal forces, creating prominent tidal tails and a bridge of gas and stars between the galaxies.[4][5]
UGC 8335 is about 400 million light-years from Earth, in the constellation Ursa Major. It is the 238th object in Halton Arp's Atlas of Peculiar Galaxies.[4]
Supernova
On 25 April 2012, Doug Rich discovered supernova SN 2012by in UGC 8335.[6][7] At the time of discovery, the supernova had a magnitude of 17.6.[8] A peak magnitude measurement of 17.3 was recorded two days later, on April 27.[6] SN 2012by was classified as a type II supernova by Tomasella et al. at the Astronomical Observatory of Padova. The research group also found that its spectrum was similar to that of SN 1996as.[8]
