Introduction
The Bachelor of Science degree emphasizes the necessary background in physics and mathematics, plus 18 credits of upper level astronomy. It is designed for students who plan to attend graduate school or work at astronomical facilities. The small size and informal atmosphere of the department encourages close working relationships between faculty and students. The undergrad students have created the League of Astronomers, which is active in outreach activities, operating the Campus Observatory, organizing an on-campus astronomy club, doing photometry and spectroscopy using instrumentation on their 12 inch telescope (provided by Student Technology Fees), and putting together a radio telescope facility on campus.
Undergraduate Learning Goals
- Understand the principle findings, common application, and current problems within Astronomy as a scientific discipline.
- Be versed in the computational methods and software resources utilized by professional Astronomers.
- Have experience operating modern Astronomical instrumentation and analyzing a range of experimental data.
- Be able to assess, communicate and reflect their understanding of Astronomy and the results of Astrophysical experiments in both oral and written formats.
- Learn in a diverse environment with a variety of individuals, thoughts and ideas.
Undergraduate Major Admission & Degree Requirements
Major Admissions Requirements
- Minimum requirements for consideration for standard admission: PHYS 121, PHYS 122, and PHY 123 (or transfer equivalent; may be presently enrolled in PHYS 123), with a 2.0 or greater cumulative GPA in the physics classes*; and either [MATH 124, MATH 125, and MATH 126] or [MATH 134 and MATH 135] (or full transfer equivalent; may be presently enrolled in MATH 126 or MATH 135).
- Admission is twice each year. Application deadlines are the third Friday of Autumn quarter and the third Friday of Spring quarter. *Winter Quarter Transfer Admission: Students transferring to the UW in Autumn or Winter quarter may also apply the third Friday of Winter quarter. Here is the application form.
- Meeting the minimum requirements does not guarantee admission. Admission is capacity constrained, and is based on a holistic review of the student’s record as follows:
- A) Academic performance. This aspect will include a review of overall GPA and content of all courses completed; frequency of incompletes or withdrawals and number of repeated courses; and an academic record that demonstrates interest in science, technology, engineering, and/or mathematics.
- B) Personal Statement. This statement will consist of a brief (500 – 1000 words) description of the student’s interest and goals in the Astronomy major, and will address strategies for success in the major. In exceptional cases with extenuating circumstances, a personal statement may also include a petition for a waiver of one of the stated minimum requirements in item 1. A more extensive list of additional topics one may wish to address in the personal statement are provided in this Google doc.
*In acknowledgement of the ongoing, extraordinary circumstances that began in Winter 2020, we understand many of you may have elected to pursue your required coursework for admission into the Astronomy major as S/NS. In addition, we are aware that many students’ overall GPAs were impacted negatively by the current International crisis starting in Winter 2020. For these reasons, we are considering Astronomy major applications with no hard GPA or course grade cut offs for Fall 2020 admissions. If you elected to take prerequisites as S/NS, or if your GPA is lower than a 2.0 in Physics 12X series courses, please include in your application a brief self-assessment of your readiness for upper-division Physics and Astronomy classes and your plans to address any deficiencies in your preparation.
Degree Requirements
The two major career paths in astronomy are professional research (generally requiring a Ph.D.) and scientific and technical support positions at observatories or in private industry. Our program prepares graduates for entrance into a graduate program or an immediate astronomy-related career. The undergraduate program also emphasizes the development of communication skills and the use of computers for data analysis in addition to formal training in astronomy and physics.
In addition to the Proficiency (Basic Skills) and Areas of Knowledge (General Education) requirements of the College of Arts and Sciences, the following curriculum (91 credits) is required for those students who wish to graduate with a major in Astronomy.

As a capstone sequence of hands-on research and dissemination of results, the following is highly recommended: ASTR 480, followed by either ASTR 481 or ASTR 499 or an REU project, and ending with ASTR 482. Furthermore, ASTR 480 & ASTR 499 are highly recommended if you are planning to apply to graduate school.
The minimum grade point to fulfill the above requirements is 2.00 in every course. Note that some of the advanced physics courses required have prerequisites which are not included in the minimum requirements for an astronomy degree. Some engineering courses may be allowed to substitute for some of the physics above (as approved by advisor).
In addition to the formal degree requirements, it is strongly recommended that every student gain a knowledge of computer programming. Introduction to Programming for Astronomical Applications (ASTR 300 – 2 credits) is highly recommended to be taken prior to astronomy 400 level courses and UNIX knowledge is required for ASTR 480.
Astronomy graduate admissions are always highly competitive, and often those students with the strongest backgrounds in physics, math, and research experience have the best chances of admission, other considerations being equal. Hence a strong preparation in physics is extremely important for students who plan to enter a graduate program. Most of our students major in physics as well as astronomy, especially since the additional requirements are modest.
It is highly beneficial for gaining admission to graduate school to have completed several credits of independent research (ASTR 499) with a faculty member.
