The Ph.D. program in Astronomy and Planetary Science prepares a student to work as an academic, government, or industrial research in astronomy or planetary science. Each student completes a ten-course core curriculum and works on an original research project under the direction of a faculty member. Research work culminates in an oral presentation and a dissertation.
To receive a Doctor of Philosophy Degree (PhD) at Northern Arizona University, you must complete a planned group of courses, from one or more disciplines, ranging from at least 60 - 109 units of graduate-level courses. Most plans require research, a dissertation, and comprehensive exams. All plans have residency requirements regarding time spent on the Flagstaff campus engaged in full-time study.

Purpose Statement
The Ph.D. program in Astronomy and Planetary Sciences is designed to provide students with a broad technical understanding of the dominant physical, chemical, and geological processes that control stellar and planetary systems while requiring students to have and present detailed mastery of their specific research topic within the field of astronomy and planetary science.
The Ph.D. program in Astronomy and Planetary Sciences leverages state-of-the-art resources found in Arizona, and especially one of a kind facilities near Flagstaff, to deliver a unique and distinct graduate education that cannot be found in Arizona’s other state universities. The Department of Physics and Astronomy will partner with Lowell Observatory, United States Geological Survey (USGS) Astrogeology Science Center, United States Naval Observatory, and the Naval Research Laboratory, as well as the Discovery Channel Telescope (DCT) and the Naval Precision Optical Interferometer (NPOI), all in or near Flagstaff. This program also capitalizes on the wide range of nearby geologic environments (including Meteor Crater) to enable terrestrial and analog planetary science investigations
Students will build skills and knowledge through formal class work and an original research project. Core coursework will focus on the development of essential skills PhD astronomers and planetary scientists need upon entering the workforce in an academic or industrial setting (instrument design and fabrication, optical design, computational approaches, big data, remote sensing, and/or techniques of observational astronomy). These courses will focus on advanced topics in astronomy and planetary science that students need for a solid foundation upon which to build their own postdoctoral research (formation and evolution of solar systems, atmospheres, interiors, and surfaces of planetary bodies, astro-chemistry, exoplanet science, and other topics). In addition, students will perform their own original research, write a dissertation, and make an oral, public presentation of their results. In the original research component, students will learn how to collect and analyze data, write up their results, and communicate their results to others in a manner consistent with professional standards in the astronomical and planetary science communities.
Students entering the PhD program in Astronomy and Planetary Sciences typically have an undergraduate degree in physics, astronomy, geology, chemistry, or similar field. Upon completing their PhD, students are likely to pursue teaching, research, technical jobs in industry or at research facilities, or similar professional opportunities that require PhD-level knowledge, tools, and experience.
