Encyclopedic overview

NGC 2936, also known as the Penguin Galaxy or the Porpoise Galaxy, is an interacting spiral galaxy located at a distance of 326 million light years, in the constellation Hydra. NGC 2936 is interacting with elliptical galaxy NGC 2937, located just beneath it. They were both discovered by Albert Marth on Mar 3, 1864. To some astronomers, the galaxy looks like a penguin or a porpoise. NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Material emanating from elliptical galaxies".

On 20 June 2013, the Hubble Space Telescope examined and photographed NGC 2936.
