Astronomy is the scientific study of celestial objects, space, and the physical universe as a whole. It seeks to understand the origins, evolution, and future of cosmic phenomena, from the smallest subatomic particles to the largest structures like galaxy clusters. Astronomers use a wide range of tools and techniques, including telescopes on Earth and in space, satellites, and computational modeling, to observe and analyze light, radiation, and other signals emanating from space.

The field encompasses a vast array of sub-disciplines. Astrophysics, for instance, applies the principles of physics to explain astronomical phenomena, investigating the physical properties of stars, planets, galaxies, and the intergalactic medium. Cosmology is concerned with the origin, structure, and evolution of the universe on its largest scales, including the Big Bang theory and the nature of dark matter and dark energy. Planetary science focuses on planets, moons, asteroids, and comets within our solar system and beyond, while exoplanetology specifically studies planets orbiting stars other than our Sun. Astrometry is the branch dedicated to precisely measuring the positions and motions of celestial objects.

Historically, astronomy has been a fundamental science, influencing navigation, timekeeping, and philosophy. Early civilizations observed the stars for practical purposes and to develop religious and mythological systems. The development of the telescope in the early 17th century revolutionized the field, leading to groundbreaking discoveries about the solar system and the nature of celestial bodies. Modern astronomy continues to push the boundaries of human knowledge, exploring questions about life beyond Earth, the fundamental laws of the universe, and humanity's place within the cosmos.
