Astronomy

Astronomy is the scientific study of celestial bodies and phenomena beyond Earth’s atmosphere. It encompasses the observation and analysis of stars, planets, moons, galaxies, and the universe as a whole. Astronomy seeks to understand the composition, behavior, origins, and eventual fate of these objects and the laws that govern their motion and interactions. It involves the use of various scientific methods, instruments, and technologies, such as telescopes and spacecraft, to gather data and test theories. The field can be divided into several sub-disciplines, including planetary science, stellar astrophysics, cosmology, and observational astronomy, each focusing on different aspects of the universe. Astronomy has ancient roots, as humans have long looked to the skies for understanding and navigation, but it has evolved into a rigorous scientific field that blends physics, mathematics, and chemistry to unveil the mysteries of the cosmos.
