Galileo Galilei

The Father of Observational Astronomy

Galileo Galilei was a pivotal figure in the scientific revolution. His groundbreaking observations and advocacy for the heliocentric model of the solar system challenged prevailing Aristotelian and Ptolemaic views, forever changing our understanding of the cosmos.

Using his improved telescope, Galileo made revolutionary discoveries, including the four largest moons of Jupiter (now known as the Galilean moons), the phases of Venus, and sunspots. These observations provided strong evidence for Nicolaus Copernicus's heliocentric theory, which placed the Sun, rather than the Earth, at the center of the universe.

Galileo's work extended beyond astronomy. He made significant contributions to the study of motion, inertia, and gravity, laying the groundwork for Isaac Newton's later work. His insistence on empirical evidence and mathematical reasoning championed the development of the modern scientific method.

Despite facing opposition from religious authorities, Galileo's relentless pursuit of knowledge and his courageous defense of scientific truth have cemented his legacy as one of history's most influential scientists.
