NGC 2207 and IC 2163 are a pair of colliding spiral galaxies about 80 million light-years away[2] in the constellation Canis Major. Both galaxies were discovered by John Herschel in 1835. So far, four supernovae have been observed in NGC 2207:

NGC 2207 is in the process of tidally stripping IC 2163.

Merging galaxies

NGC 2207 is in the process of colliding and merging with IC 2163. But unlike the Antennae or the Mice Galaxies, they are still two separate spiral galaxies. They are only in the first step of colliding and merging. Soon they will collide, probably looking a bit more like the Mice Galaxies. In about a billion years time they are expected to merge and become an elliptical galaxy or perhaps a disk galaxy.[7]
