A star field in the region of Sagittarius showing a range of stars.

Stars have long fascinated us. Remote and seemingly inaccessible, we now have a solid understanding of many of the properties and processes of stars. They are not fixed or permanent, instead they have a life cycle determined by their mass and location. In this unit you will examine the main types of stars and their sources of energy. We will apply basic properties of light and thermodynamics to determine some stellar properties.
