| Globular Cluster M 80 (which is also known as NGC 6093) is a globular cluster of stars some 28,000 lights years distant about 4o northeast of the star Antares toward the constellation Scorpius. Globular clusters are dense clusters of stars that are held together by their own mutual gravitational attraction. Globular clusters were formed early in the history of the Milky Way galaxy and are now among the oldest objects in the Universe––around 15 billion years old. Globular cluster M 80 is one of the densest of the globular clusters in the Milky Way galaxy and contains several hundred thousand stars packed into a volume about 72 light years across. Globular clusters are distributed in a more or less spherical halo that surrounds the Milky Way galaxy. |
