🌌 Introduction to Astrophysics
Astrophysics is a branch of science that applies the principles of Physics and Chemistry to the study of astronomical objects and phenomena, including the universe as a whole. As one of the founders of the discipline, James Keeler, said, astrophysics 'seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are', which is studied in Celestial Mechanics. This field of study has led to a deeper understanding of the universe and its many mysteries. The study of astrophysics has also led to a greater understanding of the Universe and its many wonders. For example, the discovery of Dark Matter and Dark Energy has revolutionized our understanding of the universe.
