Unlike open clusters found in the disk, where are the ancient, stable globular clusters located?
Answer
In the halo
Globular clusters represent the oldest stellar systems in a galaxy, having ages measured in billions of years, and they possess a dense, spherically symmetrical shape that indicates strong, stable mutual gravitational binding. This stability allows them to reside in regions far removed from the dynamic chaos of the active star-forming disk. Specifically, they are found predominantly in the Galactic halo, the vast, spherical region surrounding the main disk component of the galaxy.
