Astronomy is the study of celestial objects, such as stars, planets, and galaxies, along with their movements and origins. It focuses on observing and cataloging these objects in the universe. Astrophysics, on the other hand, is a branch of astronomy that employs the principles of physics to understand how celestial objects function and the physical properties that govern them. Astrophysics delves deeper into the physics of celestial objects, their interactions, and the processes that occur in the universe.
