Cosmology is the study of the origins, large-scale structure, and ultimate fate of the universe. It is a primarily theoretical discipline, but has been substantially influenced by empirical findings such as cosmic microwave background radiation and the Hubble expansion.
Astrophysics is the study of the physical laws and processes that drive the behavior of planets, stars, galaxies and other astronomical systems. It involves a mix of theoretical and empirical aspects, integrating fundamental theory (particularly general relativity) with observations, primarily from optical and radio telescopes.
