NGC 4194 = Arp 160 is an irregular galaxy in the constellation Great Bear , an estimated 115 million light years from the Milky Way . It is also called the "Galaxy of Medusa" because after the collision of the galaxies, a tidal tail formed, the shape of which resembles the hair of Medusa. Halton Arp organized his catalog of unusual galaxies into groups according to purely morphological criteria. This galaxy belongs to the class of galaxies with internal absorption .
The galaxy pair was discovered by William Herschel on April 2, 1791 and later listed in the New General Catalog by Johan Ludvig Emil Dreyer .
