Astronomy is the scientific study of the universe, which applies the principles of physics and mathematics to explore its origins, structure, and evolution. It involves use of the scientific method and quantitative reasoning to formulate and test models of celestial bodies such as the Sun, Moon, planets, stars, and galaxies, and to answer fundamental questions about phenomena like black holes, dark matter, the expansion of the universe, and the Big Bang. Astronomy also contributes to advancements in space exploration, satellite technology, navigation, and spaceflight.

The problem-solving skills developed through the study of astronomy are in high demand across fields such as space science, applied physics, aerospace engineering, atmospheric science, meteorology, computer science, software development, information technology, education, and more.
