stellar population synthesis

Stellar population synthesis is a scientific method used to understand the combined light from a group of stars, such as a galaxy. By analyzing the light's color and brightness, astronomers can determine the age, composition, and history of these star groups. It’s like decoding a complex fingerprint to learn about how and when the stars formed. This technique helps scientists study distant galaxies and understand the evolution of the universe by interpreting the collective signals from many stars, rather than examining individual stars directly.
