Properties of Stars

LSST will collect data on billions of stars, and each star has its own set of unique characteristics. How do astronomers determine the age of a star, its size, or its true brightness by studying the light it emits?


The H-R Diagram: A Window to the Stars

Students will learn that stars have unique properties that dictate their behavior and evolution. They will use an H-R Diagram to identify patterns and trends in star properties.
