Globular clusters are densely packed, spherical collections of stars that orbit outside the plane of the Milky Way galaxy. They typically contain hundreds of thousands to millions of stars that are bound together by gravity. Globular clusters are among the oldest structures in the universe, with ages ranging from 10 to 13 billion years old. Research on globular clusters focuses on understanding their formation, evolution, and dynamics. Scientists study the properties of individual stars within globular clusters, as well as their overall structure and motion. By studying globular clusters, researchers can learn more about the early formation of galaxies, the distribution of dark matter, and the dynamics of star clusters in general. Overall, globular clusters provide valuable insights into the history and structure of our galaxy and the larger universe.
