The study of the universe is known as "astronomy." This branch of science explores celestial bodies, such as stars, planets, moons, comets, and galaxies, as well as phenomena like black holes and cosmic radiation. Astronomers use various tools, including telescopes and space probes, to gather data and understand the universe's structure, origins, and evolution. Astronomy intersects with other scientific fields, such as physics and cosmology, helping us comprehend complex concepts like the Big Bang and the fate of the universe. This discipline has ancient roots but continues to evolve with advancements in technology, deepening our understanding of the cosmos.
