Degree Awarded: PHD Astrophysics
The PhD program in astrophysics develops creative scholarship in students and prepares them for professional careers in astrophysics, astronomy or related fields.
Students in this program take graduate-level courses in stars and interstellar media, galaxies, and cosmology; obtain quantitative skills through analysis and modelling; may have observing opportunities through regional and international telescope observatories; and conduct independent, fundamental, astrophysical research. Graduate students work closely with a research advisor on a wide range of topics including theoretical physics, cosmology, galaxy dynamics, stellar evolution, exoplanets, and developing and building instrumentation.
Graduate students in astrophysics become leaders in observational and theoretical research; they participate in NASA- and NSF-funded space missions and study topics such as how stars are born and die, how galaxies interact and evolve, and how the universe changed as it developed from its earliest beginnings.
The program's world-class faculty have research expertise across the full breadth of astrophysics including the solar system, stars and galaxies from the Milky Way and the most distant galaxies in the universe. Current ASU research applies both computational and observational approaches to the exploration of a range of topics such as fundamental cosmology and whether there is life on exoplanets.

Additional Application Information
An applicant whose native language is not English must provide proof of English proficiency regardless of their current residency.
Professionals with expertise in astrophysics are in high demand across all sectors and industries, including remote sensing, data science, instrument building, computational science, defense industries and scientific research. Coding and numerical modeling skills translate across many domains, even beyond astrophysics. Skills in the measurement and analysis of data related to the physics, chemistry, structure of the universe and exoplanetary systems are valuable to businesses and institutions relying on data-driven strategies to explore beyond the Earth and solar system.
A doctoral degree in astrophysics is required for some careers in post-secondary education and research.
Career examples include:
- astrophysics professor
- data scientist
- instrument builder
- project manager
- research astronomer
- telescope operator
