Check out our Prospective 鶹Ժ page for more information about applying to the APS Ph.D. program!

The Department of Astrophysical and Planetary Sciences is one of the few programs that combines both astrophysics and planetary science, providing a unified view of space sciences; the solar system and comparative planetology; stellar and galactic astronomy; and cosmology. 鶹Ժ are given hands-on experience with telescopes, optics, instrumentation, and computer image processing and modeling. 

The Interdisciplinary Emphasis lends itself to a career in education, science journalism, science policy, information technology, science management, or technical work where a graduate degree is not required.


The Physics Emphasis is intended for students who wish to do research and continue on to graduate work in astronomy or planetary sciences. This emphasis also lends itself well to a career in technical work related to the field.


Our Ph.D. program allows graduate students to practice teaching, assist in cutting-edge research, and begin to take part in the larger professional astrophysics community.

  • The APS department recognizes our scientific and educational missions are strengthened by contributions from diverse perspectives. We aim to promote a fair, inclusive, and supportive environment for all.  As a member organization of the American Astronomical Society, our department adheres to their and encourages all our faculty, students, and staff to do the same.
