NGC 596
NGC 596 is an elliptical galaxy in the constellation Cetus. The galaxy lies 65 million light years away from Earth, which means, given its apparent dimensions, that NGC 596 is approximately 60,000 light years across. The galaxy shows an outer envelope and is a merger remnant. The surface brightness profil is smooth and featureless.[2] The galaxy hosts a supermassive black hole, whose mass is estimated to be 170 million (108.24) .[3]
