NGC 2787 is a Lenticular Galaxy of the Hubble-type SB0-a in the constellation Greater Bear in the northern sky , about 36 million light years away from the Milky Way . The typical bar of a bar-spiral galaxy can not be seen visually at NGC 2787. Scientists suspect a supermassive black hole in the core of this galaxy . The around a dozen white dots visible in the image from the Hubble Space Telescope are not stars , but globular clusters with hundreds of thousands of stars that are held by the gravity of NGC 2787 and orbit them.
The object was discovered on December 3, 1788 by the German-British astronomer Wilhelm Herschel .
