Physics and astronomy students are driven to understand the nature of space, time, and matter from the quantum level to the outer reaches of the universe. They are intellectually curious, bright, and confident individuals preparing to make their mark in a wide range of careers.

Why Study at Iowa

The Department of Physics and Astronomy offers challenging courses on a variety of subjects. You'll begin with courses that teach problem-solving skills, logical thinking, and technical skills. Advanced classes usually have 15-20 students, allowing maximum individual attention. As you progress, you'll have opportunities to do research or participate in one of the many internships available at national laboratories and other facilities.

Outside of class, you may join the Society of Physics Students, which is open to all students interested in the subject. The society coordinates field trips and activities that foster student-faculty interaction and scientific learning.

The physics and astronomy program has about 110 undergraduate and 70 graduate students. For more information about our program and students, visit

Course Work

Students majoring in astronomy may earn a Bachelor of Arts (BA) or a Bachelor of Science (BS).

In general, the BS prepares you for graduate study in physics or astronomy and for research-related careers. The BA gives you a foundation for professional study in law, medicine, and other areas; for careers in fields such as administration, business, and technical writing; for secondary school teaching; and for graduate school. 

These courses are required for both the BA and BS degree programs:

  • Calculus I–II
  • Physics I–II–III–IV
  • General Astronomy I–II
  • Intermediate Mechanics
  • Introduction to Astrophysics I–II
  • Astronomical Laboratory
  • Additional physics and astronomy courses (choices are different for BA and BS students)

If you're earning a BS, you'll also take Calculus III and a linear algebra course. Visit the Astronomy web page for more details about course work related to astronomy.

It is possible to graduate with honors in both degree programs. With a few additional physics courses, a double major with physics is also possible.

Teaching Licensure

The BA degree program is more suitable than the BS program if you are interested in teaching science at the secondary school level. Review the College of Education's Teacher Education Program website for more information. Iowa also offers a BS in Science Education.

Student Opportunities

In addition to nearly 600 Student Organizations, Iowa students choose from multiple Living-Learning Communities, Study Abroad Programs, and Undergraduate Research Opportunities.

Most undergraduate students in the Physics and Astronomy department participate in research projects. Some work directly with faculty members. Students have worked on projects ranging from the development of ultrafast optical measurement techniques to the use of satellite data in studying interplanetary media.

Students may earn course credit for research. Some funding is available for undergraduate research through individually funded faculty projects, the Iowa Center for Research by Undergraduates, and the department's Van Allen Research Grants.

The Astrophysics Group studies a wide range of astrophysical phenomena, from solar system plasma to x-ray emission from black hole accretion discs. 

Iowa students are extraordinarily successful at competing for summer research opportunities at other top universities and at facilities such as research laboratories and national observatories.

Faculty, Facilities, and Resources

The department is recognized for its top-notch research. Its 29 faculty members work in astronomy and in nine areas of physics, including atomic and molecular, condensed-matter, high-energy, mathematical, medical, nuclear, optical, plasma, and space physics. Departmental research garners more than $16 million per year in external support.

Several faculty members are fellows of professional associations such as the American Physical Society and the American Geophysical Union. One is an elected member of the National Academy of Sciences. The late James Van Allen, a longtime professor and renowned space researcher, discovered the Earth’s radiation belts—named the Van Allen Radiation Belts in his honor.

The department has two optical telescopes and a radio telescope on the roof of Van Allen Hall and a fully automated telescope in Arizona. The optical telescope facility, run by students, is used for teaching and research projects. The department also maintains a full machine shop and 24-hour computer labs.

Additional resources on the UI campus include microfabrication facilities, the Iowa Advanced Technology Laboratories, and the Optical Science and Technology Center. Varied labs are devoted to plasma, medical, atomic, high-energy, and molecular physics. Several ultrafast laser labs, an III-V molecular beam epitaxy lab, and a high-resolution X-ray diffraction lab also are available.

Iowa City is only a few hours’ drive from the Fermi National Accelerator Laboratory and Argonne National Laboratory.


Iowa graduates have job placement rates ranging from 86-100 percent, depending on their area of study, and our Pomerantz Career Center offers multiple resources to help students find internships and jobs. 

Physics and astronomy graduates have mastered skills that are readily transferable to a number of fields. You might choose to work in research, engineering, software development, teaching, finance, biomedical research, or consulting. 

About 70 percent of physics and astronomy graduates go on to graduate school. With help from the department’s in-house recruiting office, they win acceptance to some of the best graduate programs in the country.


The Office of Admissions, the Office of Student Financial Aid, and departmental websites are great resources for students seeking scholarships.

Several scholarships are available for undergraduate astronomy majors. For example, first-year students may apply for the Shoemaker-Strickler Memorial Scholarship, which offers full tuition, fees, and a book allowance. The Strayer-Rairden Scholarship in Physics provides a renewable $1,000 award to a highly qualified applicant who has declared physics or astronomy as a major. Astronomy students also have been recipients of Presidential, Old Gold, and Goldwater Scholarships.
