At the School of Earth and Space Exploration, students in the astrophysics PhD degree program are working with faculty and researchers to discover new planets, trace the evolution of stars and galaxies, explore the origin and development of the universe, build space-flight hardware, and design instruments for telescopes and satellites.
Arizona State University is home to one of the world’s leading centers for observational and theoretical research in astrophysics. Our research interests range from the solar system to stars, to the Milky Way, to the most distant galaxies in the universe, and from computational astrophysics to fundamental questions of astrobiology.
Graduate students in astrophysics work with faculty who are leaders in observational and theoretical research and become part of our NASA- and NSF-funded space missions, studying topics such as how stars are born and die, how galaxies interact and evolve, and how the universe changed as it developed from its beginnings.
In bringing together the brightest minds in astronomy, astrophysics, cosmology, and planetary sciences, we are seeking to answer the most significant questions about our universe.
The PhD program in astrophysics is designed to develop creative scholarship and prepare students for professional careers in astrophysics, astronomy, or related fields. The degree requires 84 credit hours, a written comprehensive exam, an oral comprehensive exam, a prospectus, and a dissertation.
The majority of SESE’s admissions are for the fall semester. Spring admissions occur under special circumstances. Graduate admission to SESE consists of the following application dates for full consideration of funding and campus recruitment activities. Applications received after these dates will be considered at a lower priority for funding and visitation: December 15 of the previous year for fall admission or October 1 of the previous year for spring admission.
Most applicants will have a degree in an area related to the graduate degree they are seeking, although this is not a requirement. There is not a minimum score requirement for the GRE exams because scores are taken into consideration with the academic record and other materials as a whole. Meeting the minimum criteria does not guarantee admission to the program.
The School of Earth and Space Exploration is committed to high-impact scientific discovery. We ask important questions with deep consequences as we explore the great unknowns of our Earth, our solar system, and the universe beyond.

Additional Curriculum Information
When approved by the student's supervisory committee and the Graduate College, this program allows 30 credit hours from a previously awarded master's degree in a related field to be used for this degree.
The astrophysics PhD degree uses a research-based model and requires a written thesis and an oral defense after completion of a comprehensive examination. A minimum of 84 credit hours is required for the degree. Students submit a plan of study that details their elective course selections after conferring with the supervisory committee. All students admitted to this program are also required to take one core course and one colloquium course, each earning 1 credit hour.
