Definition
A fundamental and natural science that deals with the study, observation, measurement, and physico-mathematical interpretation of celestial bodies (stars, planets, satellites, comets, asteroids, galaxies), cosmic structures, and the universe as a whole. This discipline investigates the origin, evolution, chemical composition, and motion dynamics of matter and energy in extra-atmospheric space, being one of the oldest branches of human knowledge.
