Stellar Populations

Stellar populations refer to groups of stars in a galaxy that share similar characteristics, such as age, composition, and formation history. In astrophysics, researchers categorize stars to understand the evolution of galaxies and the universe. For instance, young stars, often found in regions of active star formation, differ from older stars that have evolved over billions of years. By studying these populations, scientists can piece together the timeline of a galaxy's development and gain insights into the processes that govern star formation and evolution across different environments in the cosmos.
