Renaissance astronomy

Renaissance astronomy was a period of significant change in understanding the universe, roughly from the 14th to the 17th century. During this time, scholars questioned long-held views based on ancient Greek and medieval ideas. The most notable shift was moving from the Earth-centered (geocentric) model to the Sun-centered (heliocentric) model, thanks to astronomers like Copernicus. Innovations in telescopes and observations by figures like Galileo expanded knowledge of planets and stars. This period laid the groundwork for modern astronomy, transforming our view of the cosmos from a fixed, Earth-centered universe to one of dynamic motion and vast scale.
