Astronomy is the oldest of all sciences. It deals with the study of stars, their energies, composition, positions, motions, and interactions. It also involves the study of individual stars within our Milky Way galaxy and galaxies outside the Milky Way. By studying astronomy, we can learn about physics that cannot be replicated on Earth and expand our understanding of the universe.
An astronomer understands how stars, planets, and other objects interact with each other. They can predict unusual events in the sky and provide critical information for research teams like NASA.
