The Milky Way galaxy is home to roughly 150 known globular clusters. These clusters are tightly packed, spherical groups of stars, typically containing tens of thousands to millions of stars. Globular clusters are generally very old. Their ages are 12-13 billion years. This age makes them among the oldest stellar objects in the Milky Way.
Messier 10 or M 10 is a bright and rich globular cluster of stars in the equatorial constellation of Ophiuchus.
At approximately 15,000 light-years from Earth it is one of the closest globular clusters. It’s estimated to be about 11.4 billion years old., making it one of the younger globular clusters in our galaxy.
