Object name: ARP240Designation(s): ARP240, NGC5257, NGC5258, Arp 240 consists of two spiral galaxies pulling material out of each other making a bridge between the two. Arp classified them under "Appearance of Fission". This is the same classification of "The Mice" and "Antennae" galaxies. Located some 300 million light-years from us I didn't get a lot of detail but you can see the bridge that connects the two galaxies. The two galaxies are NGC 5257 (right) and NGC 5258. About the same time I was taking this Hubble released a series of such colliding galaxies that included this pair. Here's a link to Hubble's image of this pair with a bit more about them.
