Globular cluster black hole, artwork. The black hole is at centre, and has been depicted in exaggerated form, with the green lines marking the paths of nearby stars that orbit it. These stars move faster when near the black hole than when further away. Studying the motion of such stars is one way to detect the presence of a black hole when other methods are not possible. The cluster's stars make up the rest of the image, and are mostly cooler (yellow) stars, with some hot (blue) stars. This black hole is in the Omega Centauri globular cluster (NGC 5139), which is around 18, 300 light years from Earth, in the constellation of Centaurus.
