The department offers four majors, astronomy, astrophysics, engineering physics, and physics. The major in astronomy consists of three possible concentrations, general astronomy, astrobiology, and astrochemistry. 

Astronomy (ASTR)

The B.A. Degree

The major in astronomy requires courses in astronomy, physics, chemistry, and mathematics. A student majoring in astronomy needs to complete the core courses and one concentration. A student may not earn more than one concentration in astronomy. The astronomy concentrations are:

General Astronomy: The General Astronomy concentration consists of courses which cover a wide range of topics in astronomy. The General Astronomy concentration prepares the student for planetarium work and/or museum education and may serve as a basis for earning state certification as a secondary school teacher of general science. Students who wish to pursue graduate study in astronomy are strongly recommended to either double-major with physics or pursue the astrophysics major.

Astrobiology: The Astrobiology Concentration consists of courses which cover a wide range of topics in both astronomy and biology. The Astrobiology Concentration provides the student an alternate route for certification as a secondary school teacher of general science. The student would have more experience with biology than a general astronomy student, which could prove advantageous for attaining secondary school science positions. Students who wish to pursue graduate study in astrobiology are strongly recommended to double-major in Biology with the General Astronomy concentration.

Astrochemistry: The Astrochemistry Concentration consists of courses which cover a wide range of topics in both astronomy and chemistry. The Astrochemistry Concentration provides the student an alternate route for certification as a secondary school teacher of general science. The student would have more experience with chemistry than a general astronomy student, which could prove advantageous for attaining secondary school science positions. Students who wish to pursue graduate study in astrochemistry are strongly recommended to double-major in Chemistry with the General Astronomy concentration.

The Department of Astronomy and Physics does not offer a B.S. degree in astronomy, but we do offer a B.S. Degree in astrophysics. Students interested in a B.S. degree in astronomy should consider pursuing the astrophysics major.
