Kepler and Galileo's Astronomical Discoveries

The video explores the evolution of European astronomy, focusing on the contributions of Tycho Brahe, Johannes Kepler, and Galileo Galilei. It highlights Tycho's precise observations, Kepler's laws of planetary motion, and Galileo's use of the telescope, which collectively advanced the heliocentric model and challenged traditional views.
