# BS in Astrophysics

## OVERVIEW

This degree is a rigorous program for those students who plan to pursue graduate studies in astronomy, astrophysics or physics and are aiming at a long-term research career. For more thoughts on why one may want to pursue a degree in astrophysics, see here.

Astrophysics requires in-depth study of the application of physics and mathematics to astronomy. Students learn about the key physics governing the universe, such as classical dynamics and electromagnetism, quantum mechanics and relativity, and practice applying these concepts to phenomena ranging from asteroids to galaxy clusters and cosmology. They learn to carry out and analyze astronomical observations, and gain research experience via a year-long senior project with a faculty member.

The overall course sequence is available as a pdf (BS Astrophysics course map), and the individual course descriptions with sample syllabi may be found here. The detailed learning objectives may be found here.

Students interested in a more flexible program as preparation for astronomy-related careers should consider the BA in astronomy.

Students interested in gaining exposure to astrophysics as a supplement to a different major may consider the Minor in Astronomy or Minor in Astrophysics.
