Astronomy is the scientific study of celestial objects, such as stars, planets, galaxies, and the universe as a whole, as well as the phenomena that occur beyond Earth's atmosphere. It is one of the oldest natural sciences, with its roots dating back to ancient civilizations that observed and documented the movements of the stars and planets. Here are some key aspects of astronomy: Observation and Data Collection: Astronomers use telescopes and other instruments to observe and collect data about celestial objects. These observations can be made in various wavelengths of light, such as visible, infrared, ultraviolet, and radio, depending on the object and the information sought. Stellar and Galactic Studies: Astronomers study stars to understand their life cycles, from birth in nebulae to death as supernovae or white dwarfs. The study of galaxies helps us understand their formation, evolution, and distribution in the universe. Planetary Science: This field focuses on the study of p...
