MegaCam Canada-France-Hawaii Telescope image of Arp 227, also known as NGC 470 and NGC 474.
The large lenticular galaxy (NGC 474, left) is interacting with a smaller companion spiral galaxy (NGC 470, right). NGC 474's spectacular shells and tidal tails may be the result of a past merger with a smaller galaxy.
