Astronomy is the study of planets, stars, galaxies, and the Universe as a whole: the physical laws that govern celestial bodies, how they originated, and how they evolve in time. As a purely observational science with few exceptions (meteorites and moon rocks), we cannot touch our objects of study directly, thus we must rely on measurements of light and subatomic particles collected by earth-based and space-based observatories and robotic space probes. The subject spans the whole of the Universe, from our home on Earth to the distant reaches of the cosmos, and all of time from the present day to the earliest moments after the Big Bang.
The Astronomy Department offers a wide range of courses: those designed for the non-major interested in learning about the latest advances in Astronomy at the GE-level, courses for undergraduate astrophysics majors, and advanced graduate courses for those preparing to pursue a research Ph.D. degree.
