Arp 148

arp 148Mayall’s Object is classified in the Atlas of Peculiar Galaxies as Arp 148. It is believed to be the result of two colliding galaxies located 500 million light years away within the constellation of Ursa Major. Astronomers believe that a pair of galaxies collided, resulting in a new object consisting of a ring-shaped galaxy with a tail emerging from it. It is thought that the original collision created a shockwave that initially drew matter into the center which then formed the ring.
