NGC 2207 and IC 2163 are a pair of colliding spiral galaxies about 80 million light-years away[2] in the constellation Canis Major.
[4] The larger spiral, NGC 2207, is classified as an intermediate spiral galaxy exhibiting a weak inner ring structure around the central bar.
Both galaxies contain a vast amount of dust and gas, and are beginning to exhibit enhanced rates of star formation, as seen in infrared images.
NGC 2207 is in the process of colliding and merging with IC 2163.
They are only in the first step of colliding and merging, with NGC 2207 being in the process of tidally stripping IC 2163.
