Astronomy and Astrophysics (BS)

Astronomy and Astrophysics is the study of planets, stars, galaxies and the universe as a whole, including how these originate and how they evolve in time. The principal pursuits of the astronomer are to extend our understanding of the physical nature of the universe and to convey this understanding to students and the general public.

The Bachelor of Science degree in Astronomy and Astrophysics offered by the Ohio State University is excellent preparation for graduate study in astronomy and other physical sciences, as well as a solid grounding for becoming a teacher in the physical sciences at the primary and secondary levels.

About 1/3 of graduates undertake advance study in physics, astronomy or other disciplines, while many others have found that the degree has prepared them for rewarding careers in many technical fields.

Career Opportunities

Individuals with MS and BS degrees in astronomy and astrophysics may also find employment at observatories, planetariums, science museums and in industry where they may assist in computational and observational research programs or participate in public education programs. At least one Ohio State astronomy alumna used her training as a stepping-stone to a career in science journalism.

Observations over the entire electromagnetic spectrum (gamma rays, x-rays, ultraviolet, visible light, infrared, microwave, and radio waves) are collected with both earth-based and space telescopes and analyzed using the tools of modern theoretical physics. The heart of the prospective astrophysicist's education consists of a firm grounding in physics plus the advanced mathematics at the core of the physics.
