Astronomy - Page 37

Astronomy is the scientific study of celestial bodies, such as stars, planets, comets, galaxies, and the universe as a whole. It involves the observation and analysis of these objects and phenomena, seeking to understand their origins, evolution, dynamics, and the fundamental laws governing the cosmos. Astronomy combines physics, chemistry, and mathematics to explore the nature and behavior of matter and energy beyond Earth's atmosphere. It encompasses various sub-disciplines, including observational astronomy, which focuses on gathering data from telescopes and other instruments, and theoretical astronomy, which involves the development of models and simulations to explain astronomical phenomena. Astronomers use a range of tools, from ground-based observatories to space telescopes, to study the universe's structure, composition, and the physical laws that govern it.
