NGC 5256

NGC 5256 is a galaxy that contains two disc galaxies, that are colliding into each other. It is located in the constellation Ursa Major, and was discovered by William Herschel on 12 May 1787. The two nuclei of the galaxies are separated by about 13046.3 light years. NGC 5256 is located at about 350 million light years away from the earth.[1][2][3][4]
