Bachelor of Arts in Astronomy and Astrophysics

When pursuing a major in Astronomy and Astrophysics, you have the opportunity to confront fundamental questions about the nature of our universe and our place in it. 

Students in the program use telescopes at campus observatories. You may also use and analyze data from the Wisconsin-Indiana-Yale-NOAO Observatories, other ground-based observatories, and space-borne observatories such as the Hubble Space Telescope. The program also offers extensive computing facilities in Swain Hall. 

The Department of Astronomy is part of the Indiana University College of Arts and Sciences. In the major, you work with world-class faculty who are recognized both for their contributions to the field and as excellent teachers.

The Department offers a Bachelor of Arts degree as well as a Bachelor of Science degree in Astronomy and Astrophysics. The B.A. major is designed for students who are interested in astronomy as the subject of a liberal arts education, and allows great flexibility in the selection of courses because the focus is on breadth of knowledge rather than on depth or specialization. The B.S. major focuses more on depth of knowledge, and as such prepares students for graduate study and a subsequent career in astronomy and astrophysics, and also for careers in related technical fields. Bachelor of Arts majors frequently seek out additional majors, minors, and certificates available in the College of Arts and Sciences and elsewhere on campus, such as related to computing, journalism, or math. The academic advisor and faculty can provide advice to you about combining Astronomy and Astrophysics with another major or degree.

The Astronomy/Astrophysics major and coursework offer training in creative, disciplined, and quantitative analytical thinking that is valuable for a great variety of careers. B.A. majors often seek employment in the field and may pursue graduate degrees in related areas. Businesses, industries and government agencies also actively seek Astronomy majors for their strong analytical and abstract reasoning skills.

The major in Astronomy and Astrophysics encompasses study of the entire universe-its past, present, and future. Topics covered in courses and/or research programs include: 

  • Our solar system-Sun, planets, asteroids, and comets
  • The life cycles of stars
  • Exoplanets
  • The origin of the elements
  • Our Milky Way galaxy and other galaxies
  • Clusters of galaxies
  • The large-scale distribution of both luminous and dark matter in the universe
  • Dark energy and cosmology

The Astronomy department also offers a minor designed to supplement other majors on campus.


Getting started

The B.A. degree in Astronomy and Astrophysics focuses on breadth of learning rather than on depth. B.A. majors are encouraged to start by getting a solid foundation in calculus and physics during the first year. Students with a strong high school math and physics background are encouraged to begin the General Astronomy sequence (AST A 221-A 222) early. However, this degree is designed to allow flexibility in course selection and you will have choices for how to begin the major. The B.S. degree, on the other hand, requires more math and physics courses and has an honors program.

Tracks and concentrations

The Astronomy and Astrophysics B.A. degree does not include separate tracks. Depending on your interests, you may choose advanced electives from related areas, including Probability and Statistics, Scientific Computing or Programming, Data Mining, Visualization, Artificial Intelligence or Autonomous Robotics, Science Writing, and Mathematics or Physics courses. This breadth of options allows you to gain useful skills and widen your opportunities.

Upper level coursework

As an Astronomy and Astrophysics major, you are required to take at least three upper level courses in Astronomy, including AST-A 305 Modern Observational Techniques and two upper level courses covering Stellar, Milky Way, Extragalactic Astrophysics, or other topics.

We encourage you to work with the academic advisor to discuss how the Astronomy and Astrophysics B.A. coursework will help you achieve your goals and complement your other interests.

Commonly pursued majors, minors and certificates

Your major represents about one quarter of your degree requirements. With the help of your academic advisor, you are able to combine several areas of interest with additional majors, minors or certificates. The B.A. degree opens up the possibility of combining diverse majors, such as Journalism, Economics, English, or History.

You should investigate degrees and minors that will provide you with important skills to complement your Astronomy degree. Here are just a few ideas:

Sometimes students majoring in other schools, such as the Kelley School of Business, the School of Informatics, Computing and Engineering, or the Jacobs School of Music, express interest in also pursuing an Astronomy major. The academic advisor will work with you to find out if it is possible for you to combine your first degree with a concurrent Astronomy and Astrophysics degree.

Enhance your major

Working with faculty

When pursuing a degree in Astronomy and Astrophysics, you have the opportunity to work with faculty who have expertise and experience in the field. Take advantage of office hours to talk with your instructors about your performance in class, the content of assignments, and how the course helps you work toward your goals.

IU STARS in Astronomy and Cox Scholars work directly with faculty mentors as soon as they arrive on campus. Acceptance to one of these programs gives you an outstanding opportunity to get involved in research your first year, acquire research skills, gain exposure to new areas of research, and receive mentoring from a leading faculty member.

You can get involved in research as early as your first year. Many incoming first year students apply to the Arts and Sciences Undergraduate Research Experience (ASURE) program. ASURE students experience project-based learning enhanced by a community of supportive faculty and peers. Choose an ASURE path in the arts and humanities, social and historical studies, or natural and mathematical sciences. Consider joining one that will deepen your skills and knowledge in an area related to your major or a different one to become a more well-rounded thinker. 

Astronomy and Astrophysics majors are strongly encouraged to participate in research on campus at IUB because our department believes it is critical for you to get involved in research as an undergraduate. Our faculty members mentor students one-on-one in research projects, which are usually observational and involve acquiring and analyzing data. You may have the opportunity to receive on-site training in data acquisition at our WIYN telescopes at Kitt Peak, Arizona, and other world-class facilities.

You might also work with space-borne data acquired by the Hubble Space Telescope, Spitzer, Galex, and others. After your research has progressed far enough, you may be encouraged to present results at professional meetings, such as those of the American Astronomical Society or even international meetings. 

The National Science Foundation funds a large number of research opportunities for undergraduate students through its REU Sites program. Talk with the academic advisor to learn more about the preparation necessary for these programs. B.S. students are better prepared to be admitted to these highly competitive programs.

You can find other summer and semester-long Astronomy research and other opportunities through the American Astronomical Society, the American Association for the Advancement of Science, NASA, and Pathways to Science.


The Department of Astronomy offers a departmental honors program for students interested in getting involved in research. However, students interested in departmental honors should consider the B.S. degree. Recent senior honors theses include research on a broad range of astronomical problems, carried out in close collaboration with faculty.

High achieving students may be recognized for Academic Excellence in the College of Arts and Sciences, or be eligible for admission to the Hutton Honors College.
