The study of planets and celestial bodies is known as astronomy. This scientific discipline encompasses the observation and understanding of various phenomena beyond Earth, including stars, galaxies, moons, and comets. Astronomy employs various tools and techniques, such as telescopes and space probes, to gather data and make discoveries about the universe’s formation, structure, and evolution. It is divided into different branches, including astrophysics, which focuses on the physical properties and underlying mechanisms governing celestial phenomena. Astronomy plays a fundamental role in expanding our knowledge of the cosmos.
