Messier 75 is a spherical collection of hundreds of thousands of old stars bound together by gravity, located about 67,000 light-years away in the constellation Sagittarius. It's one of the densest known globular clusters, making it valuable for astronomers studying how stars age and interact in crowded stellar environments.
