## 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.
