Mayall's Object (also classified under the Atlas of Peculiar Galaxies as Arp 148) is the result of two colliding galaxies located 500 million light years away within the constellation of Ursa Major. It was discovered by American astronomer Nicholas U. Mayall of the Lick Observatory on 13 March 1940, using the Crossley reflector . [ 4 ]
Interacting galaxies (colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. An example of a minor interaction is a satellite galaxy disturbing the primary galaxy's spiral arms. An example of a major interaction is a galactic collision, which may lead to a galaxy merger.
NGC 2623 gained its unusual and distinctive shape as the result of a major collision and subsequent merger between two separate galaxies. [9] This violent encounter caused clouds of gas within the two galaxies to become compressed and stirred up, in turn triggering a sharp spike of star formation.
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, with NGC 2207 being in the process of tidally stripping IC 2163. Soon they will collide, probably looking a bit more like the Mice ...

NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet". On 20 June 2013, the Hubble Space Telescope examined and photographed NGC 2936. [5] NGC 2936 once had a flat, spiral disk. The orbits of the galaxy's stars have been perturbed due to gravitational tidal interactions ...
NASA has captured what it looks like when two galaxies collide. The image is of Arp 299, about 140 million light years away from Earth, and has been merging for millions of years.
