Black holes in galactic nuclei - Figure 3


The giant spiral galaxy in the constellation of Andromeda (M31), with its two smaller companions: NGC 205 (left) and M32 (right). The galaxy M32 is suspected to harbor a three million solar mass black hole in its nucleus. See this animation for an illustration of the effect that the black hole has on the motions of the surrounding stars.
