Galileo was essentially one of the first astronomers. He did not invent the telescope but he did improve it. The telescope was invented in 1603 in Holland by Hans Lippershay, a dutch spectacle maker. He is also the first person to prove the Sun rotates on its axis and that the Earth rotates on its axis and that it revolves around the sun based on Copernican's theory. Galileo invented the horse powered water pump. He also set down the foundation of the Newton laws.
He was an Italian astronomer who lived around 1600 and carried on a long dispute with Vatican theologists over whether the Earth or the Sun was at the centre of the universe (as known at that time) . . . . . . Difficult to say what his most important discovery was, but one important one was the discovery of moons in orbit around Jupter. This was the first time anything had been discovered that could be shown not to be revolving round the Earth, and with later evidence it led - after Galileo's lifetime - to the acceptance of the heliocentric theory, with the Sun at the centre.
Galileo Galilei is most famous for his discovery that the Earth was not at the center of the solar system, and the fact that the Earth orbits the Sun, and not vice versa.
Galileo is considered to be the founder of the science of physics, because he was the first to show that the fundamental properties of the physical universe could be systematically investigated by observation and logical analysis, rather than by pure speculation as had previously been done. In terms of specific discoveries, perhaps the most important was the discovery that the weight of an object does not affect the speed at which it falls.
Galileo's most significant observation and discovery was that the universe (or now the solar system) was Sun-Centered. Originally, people accepted the Copernican theory that the universe was Earth-centered. For a few years Galileo had to defend his discover until 1616.
He made a big difference by challenging old accepted theories and making important discoveries in astronomy and dynamics. Maybe his most important discovery was the moons of Jupiter, the first time any objects had been seen that definitely did not orbit the Earth. This encouraged Galileo to take up the Copernican heliocentric theory which has the Sun at the centre of the local system of planets known as the Solar System. Science did not fully demonstrate the accuracy of the heliocentric theory until the 19th century but Galileo's important contribution was to stimulate the debate. His disagreement with the catholic church was taken up by protestant propagandists, which did nothing for the quality of the scientific debate, but gradually the heliocentric theory became universally accepted by the first half of the 19th century.
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.
he made phrases of the moon and first to use a telescope
He found the Galiliean Moons and improved the telescope.
Galileo Galilei. Perhaps his most important discovery was finding that acceleration due to gravity is independent of the objects mass.

Galileo was another of the most important philosophers in ancient history. He was motivated in his exploration by his religion and curiosity.
