1609 AD.
He found the Galiliean Moons and improved the telescope.
Galileo Galilei was an Italian physicist, mathematician and engineer, who contributed largely to the scientific revolution. He invented a pendulum clock, which was inspired by a swinging chandelier in the Cathedral of Pisa.
Galileo Galilei is best known for his work in astronomy and physics, particularly for being the first to use a telescope to study the stars and planets. His observations and experiments challenged prevailing beliefs about the nature of the universe and laid the foundation for modern science.

Galileo Galilei is remembered for his contributions to astronomy, especially for his observations with the telescope that supported the heliocentric model of the solar system proposed by Copernicus. He also made significant advancements in the fields of physics and mathematics. Galileo's work laid the foundation for modern observational astronomy and the scientific method.

The invention of the telescope is credited to Hans Lippershey, a Dutch spectacle maker, who applied for a patent for the device in 1608. However, it was Galileo Galilei who significantly improved upon Lippershey's design and used it to make groundbreaking astronomical observations in 1609, including the moons of Jupiter and the phases of Venus. Galileo's work laid the foundation for modern astronomy, showcasing the telescope's potential to explore the universe.
Galileo's biggest contribution to science was the way he learned about mechanics. Instead of just observing a in nature, he set up experiments. In fact, Galileo was the first scientist to routinely use experiments to test his theories.
Galileo Galilei (15 February 1564 - 8 January 1642) was a Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism. Galileo has been called the "father of modern observational astronomy", the "father of modern physics," the "father of science," and "the Father of Modern Science."

Galileo Galilei proved that objects in the solar system orbit around the sun, not the earth. He found this out by observing variations in venus's phases that could not be explained if all objects orbited the earth
