Johannes Kepler’s 1609 masterpiece, Astronomia Nova (New Astronomy), is one of the most significant pillars in the history of science. Along with Copernicus’s De revolutionibus and Newton’s Principia , this single text shattered centuries of geocentric dogma and reshaped our understanding of the cosmos.
