Globular clusters contain some of the oldest known stars, often over 10 billion years old.
They are found in the halo of galaxies and can provide insights into the early stages of galaxy formation.
These clusters lack significant amounts of gas and dust, indicating little to no new star formation occurs within them.
The density of stars in a globular cluster is much higher than that in open clusters or within galaxies themselves.
Studying globular clusters helps astronomers estimate the age of the universe by comparing their stellar populations to theoretical models.
