Question

Difference between astrophysics and nuclear physics

Answer 1

Astrophysics is often thought of as a subspecialty of astronomy, and the difference is subtle. Astronomy, one of the oldest sciences, consists of observing and cataloging the positions and motions of the stars, planets and other heavenly bodies. Generally speaking, practicing astrophysics implies applying chemistry and physics to better understand astronomical observations, including the origin, nature and eventual fate of the heavenly bodies.

Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. Other forms of nuclear matter are also studied. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons.

Answer 2

astrophysics is related to space. nuclear physics is the smaller end. Astrophysics is about the big stuff like planets and stars.
Nuclear physics is about the small stuff like atoms and protons and neutrons
