Astronomy

Definition of Astronomy as it relates to Science, Medicine, Physics

Astronomy is the scientific study of celestial objects and phenomena outside Earth's atmosphere. It involves observing stars, planets, comets, galaxies, and other interstellar bodies to understand their physical properties, chemical composition, and evolution. As a subfield of physics, it employs principles from mechanics, electromagnetism, statistical thermodynamics, quantum mechanics, and relativity to explain astronomical observations and phenomena. Astronomy has strong ties with other scientific disciplines like chemistry, biology, geology, and mathematics, making it an essential component of the broader fields of science and medicine. By studying the universe's composition, structure, and behavior, astronomy contributes significantly to our understanding of the origins, evolution, and fate of the cosmos.
