What was Galileo galilei known for?

Answer 1

Some of Galileo's accomplishments were the improvement of the telescope and the discovery of evidence that showed that the moon and other planets were not "wandering stars" but physcial bodies like Earth. Such evidence was the discovery of craters and mountains on the moon, sunspots on the sun and 4 of Jupiter's moons.

Answer 2

He gave credence to Copernicus's claims that the Sun was the center of the universe, not the Earth. He also perfected the USE of the telescope, he DID NOT invent it. (The telescope was invented by Hans Lippershey in 1608). With his telescope, he observed sun spots, proved that the Moon had mountains and craters, discovered the largest four moons of Jupiter, and that Venus goes through phases.

Answer 3

A great Italian astronomer and physicist, renowned for his epoch-making contributions to physics, astronomy, and scientific philosophy. In 1610, he was among the first to use a telescope to study the heavens and with it discovered the four big moons of Jupiter, the phases of Venus, the mountains of the Moon, and the starry nature of the Milky Way, breakthroughs that he announced the same year in his Siderius Nuncius (Starry Messenger). His defense of the Sun-centered heliocentrismin Dialogue on the Two Chief World Systems (1632) brought severe censure from the Church and he was forced to recant before, at the age of 69, being sentenced to life imprisonment (commuted to house arrest); he was not formally exonerated by the Catholic Church until 1992. Having heard, in 1609, of the invention of the telescope, but lacking a detailed description, he set about learning the principles of the instrument himself and, within a matter of weeks, had produced his first simple "optik tube," which he immediately directed to the skies. Thus began a new and exciting era of observational astronomy that continues to this day. Galileo made a number of telescopes ranging up to 5 cm in aperture and 170 cm in focal length, and with magnifications from about 8 to 30.

Answer 4

Some of his achievements were mathematically proving that earth and other planets orbited the sun and also improving the telescope to actually prove that theory. Now, of course he did much more, but those are just some of the things he's most known for.

Answer 5

Galileo was the first to make important astronomical discoveries using a telescope. He discovered the four largest moons of Jupiter. His discovery that they orbit round Jupiter was the first indication that not everything in the universe orbits round the Earth.

Galileo made important discoveries in physics and is said to be the founder of the science of dynamics, which is the branch of physics concerned with moving objects.

In the latter part of his life he publicised the idea that the Earth itself orbits the Sun, as proposed by Copernicus, and provoked a famous dispute with the Catholic church which examined the proposal in a court case, after which Galileo recanted after not being able to provide evidence for it.

Later scientific discoveries showed that the idea that the Sun is at the centre of the solar system is correct, but that was after Galileo's lifetime.

Answer 6

He invented the telescope, the thermometer and thought of the idea to use pendulums in clocks, he is known as the father of the scientific revolution.

Answer 7

He discovered many planets and proved that the planets orbited the sun. He was also the first to invent the telescope.

Answer 8

The invention of the telescope, and discovering that the planets revolved around the sun- not the earth.
