Astronomy

Astronomy is the scientific study of celestial objects, such as stars, planets, comets, and galaxies, as well as the phenomena that occur outside Earth’s atmosphere. It involves the observation and analysis of these entities to understand their characteristics, behaviors, and origins. Astronomy encompasses various subfields, including astrophysics, planetary science, and cosmology, which explore different aspects of the universe and its contents. The primary tools of astronomers include telescopes and other instruments that collect and analyze light and other radiation emitted by celestial bodies. The discipline also involves mathematical calculations and theoretical models to explain the physical laws governing the universe. With roots dating back to ancient civilizations, astronomy has evolved significantly, leading to a deeper understanding of the universe and Earth’s place within it.
