Astronomy

The Department of Astronomy at Boston University offers a comprehensive undergraduate program designed to provide students with a solid foundation in the fundamental principles of astrophysics, observational techniques, and data analysis. This program aims to cultivate a deep understanding of the universe, from the smallest cosmic particles to the largest galactic structures. Students pursuing a degree in Astronomy gain hands-on experience through laboratory work, astronomical observations, and research projects that utilize state-of-the-art telescopes and computational tools. The curriculum encompasses a broad range of topics including planetary science, stellar astrophysics, cosmology, and astrophysical instrumentation, preparing graduates for diverse careers in research, education, and industry.

Throughout the program, students are encouraged to develop critical thinking and problem-solving skills, as well as proficiency in programming languages and data management essential for modern astrophysics. The program also emphasizes interdisciplinary approaches, linking astronomy with physics, mathematics, and computer science to facilitate a comprehensive understanding of the physical universe. Undergraduate students have opportunities to participate in ongoing research projects alongside faculty members, attend seminars, and present their findings at various scientific conferences. In addition to academic coursework, students can engage in internships and collaborative projects with professional observatories and research institutions.

Graduates of the Astronomy program at Boston University are well-equipped for further study or careers in astrophysics, space exploration, data science, and related fields. The department’s strong connections with research institutions and its extensive alumni network provide valuable opportunities for mentorship, internships, and employment. Whether pursuing graduate studies or entering the workforce directly, students leave the program with the skills, knowledge, and experience necessary to contribute to the advancing field of astronomy and our understanding of the universe.

In addition to the requirements listed below, all students are expected to participate in a journal club and seminar series (GRS AS 850, 851, 865, 866) each semester that they are in residence, although they will only receive a total of four academic credits toward their degree by taking these courses.

Students must accumulate 64 credits with a grade of B− or higher from graduate-level classes. Course requirements are as follows:

• 32 credits must be 4-credit astronomy (AS) courses numbered GRS 701–749
• 12 credits must be advanced AS courses numbered GRS 750–799 or, with the permission of the director of graduate studies, graduate-level physics or engineering courses
• 4 credits must be research preparation courses (or approved substitutes), including:
  • GRS AS 802 Graduate Research and Scholarship
  • GRS AS 803 Research Methods in Astronomical Data Analysis
• 4 credits of AS seminar courses:
  • GRS AS 850/851 Astrophysics Seminar
  • GRS AS 865/866 Space Physics Seminar

No more than 12 credits may be for research courses numbered GRS AS 900–919.

Students with prior graduate work may be able to transfer course credits. For details, see the GRS Transfer of Credits policy.

Comprehensive Examination

Students must pass both the written Astronomy Comprehensive Examination and the Oral Qualifying Examination. The written Comprehensive Exam consists of two 3-hour written tests administered on two separate days. The exam is designed to test the student’s ability to solve quantitative problems in astrophysics and space physics using both knowledge of the material covered in the core courses (GRS AS 700–749) and application of basic physical principles. The written Comprehensive Exam must be passed no later than the spring semester of a student’s second year in the program.

After passing the written Comprehensive Examination, a student must take the Oral Qualifying Examination within the subsequent academic year. During this year the student should undertake a directed research project with a member of the faculty. Ideally, the research should lead to a potential dissertation topic. The purpose of this directed research is to ensure that the student has the preparation and the ability to conduct the original research required for the PhD thesis. It is expected that the directed research will lead to publishable results.

The Oral Qualifying Examination is based on the directed research: the student presents the results of the research in a formal seminar and is examined afterward by a panel consisting of the student’s research advisor and other members of the Department of Astronomy faculty. The panel questions the student, not only about his or her research, but also about the student’s knowledge of related fields of physics and astronomy.

Dissertation and Final Oral Examination

Candidates must demonstrate their abilities for independent study in a dissertation representing original research. A prospectus for the dissertation must be completed and approved by the readers, the director of graduate studies, and the department chair/program director. Candidates must undergo a final oral examination in which they defend their dissertation as a valuable contribution to knowledge in astronomy, astrophysics, or space physics. They must also demonstrate a mastery of their fields of specialization. All portions of the dissertation and final oral examination must be completed as outlined in the GRS General Requirements for the Doctor of Philosophy Degree.

It is possible for a student admitted to the Astronomy PhD program to leave the program with an MA degree only. This may occur if the student fails to complete the PhD requirements and/or if the student decides that he or she no longer wishes to remain in the PhD program. To exit the program with an MA, the student must fulfill all of the requirements listed for the MA in Astronomy.

The Astronomy undergraduate program at Boston University offers a range of financing options to support students throughout their studies. Tuition fees for the program vary depending on the student's status as a resident or non-resident of Massachusetts. For in-state students, the annual tuition is approximately $58,000, while out-of-state students pay around $58,000 as well, with additional fees for laboratory and material costs. To assist students with these expenses, Boston University provides numerous financial aid opportunities. Merit-based scholarships are awarded based on academic achievement, standardized test scores, and extracurricular involvement, with some scholarships covering a significant portion of tuition. Need-based financial aid is also available, and students are encouraged to complete the Free Application for Federal Student Aid (FAFSA) and the university's Financial Aid Application to determine eligibility for grants, loans, and work-study programs. The university participates in federal loan programs such as the Stafford and Perkins Loans, which offer low-interest borrowing options. Scholarships and fellowships specific to science and astronomy are available through departmental funds and external organizations. The university also offers work-study programs that enable students to gain practical experience while offsetting educational expenses. Additionally, many students supplement their income through on-campus employment opportunities. Boston University is committed to making higher education accessible, and its financial aid counselors assist students in navigating the application process to maximize available support. Furthermore, students are encouraged to explore external scholarships from astronomy associations, scientific societies, and private foundations that support STEM education. For international students, specific scholarship opportunities and financial support options are available, but applicants are advised to plan ahead due to potential visa-related financial requirements. Overall, the university's comprehensive financial aid system aims to minimize financial barriers and ensure that qualified students can pursue a degree in astronomy at Boston University without undue hardship.
