Light is a vital tool in astronomy but we can do more with it than just take pretty pictures. In this class we will learn how astronomers split light into the electromagnetic spectrum, what that is, and what that can tell us about various objects throughout the universe. There will be an interactive demonstration to help students understand the physics behind why splitting light emitted from celestial objects creates useful scientific data. Once we know how the data is collected, we will connect it to current research topics in astronomy.
