9 Most Important Astronomical Discoveries

From ancient stargazers mapping the heavens to Einstein bending the fabric of space-time, the history of astronomy is a story of breathtaking revelations. Each discovery shattered old beliefs and opened our eyes to a universe far stranger and more magnificent than anyone imagined. In this video, we explore the 9 most important astronomical discoveries that changed how we understand the cosmos. From Copernicus proving Earth orbits the Sun, to Kepler's laws, Galileo's telescope, Hubble's expanding universe, and the search for habitable exoplanets, we trace the milestones that shaped modern astronomy.
