Quick Answer
A globular cluster is a tightly packed spherical group of very old stars orbiting a galaxy. Some globular clusters contain hundreds of thousands or even millions of stars.
The Full Story
Globular clusters are dense, roughly spherical systems of stars bound by gravity. They are among the oldest known stellar systems, often containing stars formed early in a galaxy’s history. The Milky Way has more than 100 known globular clusters, including famous examples like M13 in Hercules. Their age and composition make them valuable for studying the early history of galaxies.
