天体物理学天文学
Astrophysics is the study of the physical and chemical properties of astronomical objects such as stars, galaxies, and the interstellar medium. Astronomy, on the other hand, is the study of the motion, evolution, and composition of celestial objects. Astrophysicists use mathematics and physical laws to explain the behavior of objects in space, while astronomers use observation and analysis to make discoveries about the universe.
