Galileo made significant improvements to the telescope, allowing for better magnification and clarity. His observations confirmed the phases of Venus and the moons of Jupiter, supporting the Copernican heliocentric model.
Galileo Galilei was an Italian astronomer, physicist, and engineer. Known as the "Father of Modern Science," his work laid the foundation for modern physics and observational astronomy.
Heliocentric Theory: Galileo’s observations provided crucial evidence for the
heliocentric model proposed by Copernicus.
Scientific Instruments: He developed several scientific tools, including an
early thermometer and the improved telescope.
