Description

NGC2207 and IC 2163 are a pair of colliding spiral galaxies about 80 million light-years away in the constellation Canis Major. Both galaxies were discovered by John Herschel in 1835. So far three supernovae have been observed in NGC2207 (SN 1975A, SN 1999ec and SN 2003H). NGC2207 is in the process of tidal stripping IC2163. IC2163 Mag 12.4. NGC2207 is in the process of colliding and merging with IC2163. 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.
