BS in Astrophysics

For students interested in graduate studies in astronomy, astrophysics or physics

Why pursue an astrophysics degree?

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.

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.

Degree requirements are listed below and on the UH Manoa Catalog.
