Stellar population studies

Stellar population studies involve analyzing groups of stars within galaxies to understand their age, composition, and formation history. By examining properties like brightness, color, and chemical makeup, astronomers can determine when different stars were born and how galaxies evolved over time. These studies help us learn about the universe’s past, how galaxies grow, and the life cycles of stars. Essentially, they provide a detailed snapshot of the stellar community within galaxies, revealing clues about the cosmos' development and the processes shaping it.
