The elliptical galaxy M87 is the home of several trillion stars, a supermassive black hole, and a family of 13,000 globular star clusters. It is the dominant galaxy at the center of the neighboring Virgo cluster of galaxies, which contains some 2,000 galaxies. Being in the center of the Virgo cluster, M87 may have accumulated some of its globular clusters by gravitationally pulling them from nearby dwarf galaxies that seem to be devoid of globulars today.
