After Galileo built his first telescope in 1609, he observed and described the landscape of the moon, discovered four of the moons of Jupiter, discovered the phases of Venus, and discovered sunspots. Galileo's discovery of sunspots supported the idea of heliocentrism, a model that places the sun at the center of the universe with the planets orbiting around it.Continue Reading
Galileo studied and later taught mathematics at the University of Pisa. He helped to describe ballistics and presented his "Principle of Inertia." In 1632, Galileo presented his concept of basic relativity in physics, which later became the basis of Einstein's special theory of relativity.
In 1632, Galileo published a book openly supporting heliocentrism. He was later forced to publicly denounce his findings.Learn more about Astronomy
Galileo is famous for many things but is probably best known for discovering Jupiter's four moons. The moons around Jupiter are called "Gallilean moons."Full Answer >
While he did not invent the telescope, Galileo modified one of the devices before discovering a number of planets and moons, including Venus, which inspired a scientific revolution. His contention that Copernicus was correct about a heliocentric galaxy drew the ire of the Vatican, which believed the Earth was at the center of the galaxy. Galileo later published his findings, which resulted in his imprisonment.Full Answer >
Galileo's full name is Galileo Galilei. He was an Italian mathematician who is well known for his significant work in laying the foundation for modern physics and astronomy.Full Answer >
Galileo Galilei, more commonly known simply as Galileo, was an Italian scientist and astronomer active during the late 1500s and early 1600s whose pioneering observations and studies have been credited as the birth of modern physics and astronomy. He was a supporter of the Copernican theory that the sun resides at the center of the Solar System and that the Earth rotates around it.Full Answer >
