Astronomy is the oldest of the natural sciences, dating back to antiquity. The earliest astronomers were simply observers of the night sky, but over time they began to develop theories about the nature of the universe.
One of the earliest civilizations to make significant contributions to astronomy was the Babylonians. They developed a system of constellations and recorded the movements of the planets. The Babylonians also developed a calendar that was based on the solar year.
The Greeks were also important contributors to the development of astronomy. They made significant advances in our understanding of the solar system and the stars. The Greek astronomer Ptolemy developed a model of the universe that was widely accepted for centuries.
