Astronomy

Astronomy is the study of the universe beyond the Earth's atmosphere, including stars, galaxies, planets, and other celestial bodies. Astronomers use a variety of tools and techniques, including telescopes, satellites, and computer simulations, to observe and analyze the universe. Major research areas in astronomy include the structure and evolution of the universe, the properties and behavior of stars and galaxies, the search for extraterrestrial life, and the study of cosmic phenomena such as black holes, supernovae, and gamma-ray bursts. Astronomy has greatly contributed to our understanding of our place in nature and the universe, and has stimulated new discoveries and innovations.
