Discovered by Charles Messier in 1764, M9 is a large globular cluster located near the center of our galaxy, the Milky Way. Globular Clusters are some of the oldest objects of the galaxy, providing clues about it’s evolution and structure. There are also several dark clouds of interstellar dust nearby, which are featured in the first image above. While M9 can be seen with decent binoculars, it is only with large telescopes that the cluster comes into full view.
