The study of the universe beyond the Earth's atmosphere is known as "astronomy." This scientific discipline explores celestial bodies, including stars, planets, galaxies, and the overall structure of the universe. Astronomers use various tools such as telescopes, satellites, and space probes to collect data and understand cosmic phenomena. Astronomy encompasses a wide range of topics, including the origins of stars, planetary systems, black holes, and the potential for extraterrestrial life. The field continuously evolves as new discoveries are made, deepening our understanding of the universe and our place within it.
