Dear Ariana,
BSc physics and BSc astrophysics are two courses.
BSc Physics is an undergraduate program about natural science that involves the study of matter and its motion through space-time, along with related concepts such as energy and force.
Whereas, B.Sc. in Astrophysics is an undergraduate involving the study of the physical and chemical properties of celestial bodies and the natural phenomena that occur in the universe

I hope this information helps you

All the best
