Astronomy is the scientific study of celestial objects and phenomena beyond Earth’s atmosphere, including stars, planets, galaxies, nebulae, black holes, and the vast cosmos itself. It explores the origins, evolution, and fate of the universe through observation, theory, and cutting-edge technology such as telescopes, space probes, and satellite missions. From mapping distant galaxies to detecting exoplanets and probing cosmic microwave background radiation, astronomy connects physics, mathematics, and chemistry to unravel the mysteries of space and time—revealing our place in the universe and inspiring ongoing discoveries across astrophysics and cosmology.
