How long will the Sun shine? How do we discover Earth-like planets among the many exoplanets circling other stars? How did the universe begin and how has it evolved over its 13.8-billion-year history? How do we detect not only light but also gravitational waves from afar? Astronomy is the science that asks and tries to answer questions like these. We have come a long way toward understanding what makes the sky appear as it does and how the Universe behaves. The Astronomy Department offers courses for anyone who is interested in learning about the Universe, and who would like to be able to follow new astronomical discoveries as they are made. All courses in Astronomy satisfy the Division III requirement. We offer an Astronomy major and an Astrophysics major (administered jointly with the Physics Department).
