Studying astronomy or astrophysics can be pursued through a physics major, as many professionals in the field hold a bachelor's in physics followed by a master's in astrophysics. The University of California system offers limited direct astronomy programs, but a physics degree provides a solid foundation for entering astronomy-related fields. At the undergraduate level, physics curricula focus more on general physics concepts rather than specialization, which aligns with the educational path of many astrophysicists. For instance, at UCSC, the distinction between physics and astrophysics degrees is minimal, primarily differing in lab components. This pathway allows for flexibility in career options and advanced studies in astronomy or astrophysics later on.
