Overview

Astrophysicists apply physics and mathematics to the study of planets, stars, galaxies, pulsars, black holes, quasars and the universe, among many other fascinating objects in order to understand their origin, evolution and ultimate fate. Students who major in astronomy or astrophysics usually have very inquisitive minds and a good aptitude for physics and mathematics. The bachelor degree programs in astronomy and astrophysics provide the student with a solid background in laboratory and theoretical astrophysics as well as in the fundamentals of physics and mathematics. Research opportunities are available to supplement classroom instruction.

B.S. in Astrophysics 

The bachelor of science degree in astrophysics is designed for students who wish to go on to graduate studies in astrophysics with the goal of becoming professional astronomers. Professional astronomers generally find positions at colleges, and universities, national labs, NASA or its contractors and in various space industries. This degree also prepares you for many jobs in related fields such as computer science, mathematics or physics.

B.A. in Astronomy 

The bachelor of arts degree in astronomy is intended for students who desire a broad background in astronomy, mathematics and physics but do not plan to do graduate work in astrophysics. With this broad background, the student is well prepared in many fields of endeavor, including planetarium and museum work, teaching astronomy at colleges and universities, secondary education, science writing, or, in fact, in many professions in which the ability to learn is critical.

Both of these degrees can be profitably combined with mathematics and other sciences producing excellent double majors or double degrees.

Declare an Astronomy Major

Students in the CAS are required to declare a major by the end of their sophomore, or fourth, semester. If students are still undecided at that time they should reach out to the CAS Advising Center via inadvise@lehigh.edu as well as the Center for Career and Professional Development for assistance with finding an appropriate career path.
