Astronomy - Page 3

Astronomy is the scientific study of celestial objects, space, and the universe as a whole. It encompasses the observation and analysis of stars, planets, comets, galaxies, and cosmic phenomena, seeking to understand their origins, evolution, dynamics, and the laws governing them. As one of the oldest sciences, astronomy utilizes a range of tools and techniques, including telescopes, satellites, and computer models, to gather and interpret data about the cosmos. It blends aspects of physics and mathematics to develop theories about the universe, such as the Big Bang, black holes, and the life cycles of stars. Astronomy is divided into various subfields, including observational astronomy, which focuses on acquiring data from celestial phenomena, and theoretical astronomy, which involves developing models to explain those observations. Through advancements in technology and interdisciplinary approaches, astronomy continues to expand our knowledge of the universe and our place within it.
