Astronomy - Page 21

Astronomy is the scientific study of celestial objects, space, and the universe as a whole. It encompasses the observation and analysis of stars, planets, moons, galaxies, and other cosmic phenomena. Astronomy seeks to understand the origin, evolution, and eventual fate of the universe, as well as the physical laws governing celestial bodies. It involves various disciplines, including observational astronomy, which focuses on collecting data from telescopes and other equipment; and theoretical astronomy, which uses mathematical models and simulations to explain astronomical observations. The field has evolved over centuries, incorporating advancements in technology and expanding our knowledge beyond the limits of the solar system to include distant galaxies and cosmology, the study of the universe's large-scale structures.
