In which distinct region of the galaxy do ancient globular clusters predominantly orbit?
Answer
Galactic halo
Globular clusters exist in a different gravitational environment than open clusters, indicating their ancient origins tracing back to the galaxy's formation era. While open clusters reside in the galactic disk where active star formation takes place (like the spiral arms), globular clusters orbit in the sparsely populated galactic halo that surrounds the main disk structure. This fundamental difference in location highlights their contrasting ages and histories within the galaxy.
