The word “astronomy” comes from the Greek language and is derived from two ancient Greek words: ἄστρον (astron), meaning “star”, and νόμος (nomos), meaning “law” or “culture”. Therefore, astronomy literally translates to “the law of the stars”. This etymology reflects the early focus of the field on the study and understanding of stars and celestial bodies.
Astronomy is one of the oldest sciences, with its origins tracing back to ancient civilizations that observed the night sky. These early astronomers used their observations of the stars, planets, and other celestial objects to navigate, keep time, and form the basis of early calendars. Over centuries, as observational techniques and theoretical knowledge advanced, astronomy evolved into the sophisticated and comprehensive scientific discipline it is today, focused on the study of celestial objects and phenomena beyond Earth’s atmosphere.
