The Revolutions of the Celestial Spheres

"The Revolutions of the Celestial Spheres" is a significant work by the astronomer Nicolaus Copernicus, published in 1543. It challenged the long-standing geocentric model, which placed the Earth at the center of the universe, by proposing a heliocentric model where the Sun is at the center, and the planets, including Earth, revolve around it. This revolutionary idea laid the foundation for modern astronomy, changing our understanding of the cosmos and influencing scientists like Galileo and Kepler. Copernicus's work marked the beginning of a shift towards a more accurate view of our solar system and the universe.
