Galileo observed that the planets Mercury and Venus pass through phases just like the Moon. The only way this could happen is if they circled the Sun, and not the Earth. Most importantly, he discovered that Jupiter had four moons. In the 1609, Galileo heard about a new invention called a telescope. He decided to build a telescope and use it to look at the Universe. That is just what he did and that is how he learned about the universe.
Yes Galileo was very important, because if he wasn't born than we might not even now about the stars, the planets, the moon, or even about the universe. And why is that? That is because Galileo was the one whom discovered it. Galileo was also the one whom "invented" science, math, and other great things we now do in school today. Galileo was the one whom invented the telescope, the thermometer, and other great and useful things that we use in our every day lives.
No. He discovered great moons, which, had they not been orbiting planets might have been considered planets themselves, but the first new planet since antiquity was Uranus, discovered by Sir William Herschel.
Because the Sun has a great gravitational pull on the planets. Without the Sun the planets would travel in straight lines (ignoring other gravitational forces in the Universe.)
A: To our solar system the distance is great But compared the the universe it is inches away
The 1500's was considered the Renaissance (although, perhaps late in the Renaissance movement). I'll hit this a little from both ends.Leonardo da Vinci (1452 to 1519) was considered a great inventor, scientist, and painter. He had several detailed anatomy studies, and made drawings of weapons, "flying machines", helicopters, and bridges. Many of his drawings never were built, or weren't attempted for another 500 years.Nicolaus Copernicus (1473 to 1543) is often considered the father of modern Astronomy. Aristotle had placed the earth in the center of the universe and the planets and sun orbiting around the earth which didn't fit well. Copernicus changed this with the sun as the center of the universe and the earth and planets orbiting around the sun.Hans Lippershey (1570 to 1619) Invention of the telescope (1608).Galileo Galilei (1564-1642). Made a crude water thermometer in 1593.Used telescope to observe planets. Discovery that the planets weren't just points of light. Discovery of moons around Jupiter (using the telescope above, 1610).
Hydrogen is the most abundant element in the universe, making up 75% of ...Thiselement is found in great abundance in stars and gas giant planets.
Copernicus hypothesized (discovered) that the Sun is the center of the universe and that the Earth isn't. (Actually the Sun is not the center of the Universe but it its the center of our solar system). At that time the church thought that the Earth was the center of the universe and they thought that they were right all the time and Nicolas Copernicus proved them wrong and they got angry at him for doing that because a lot of people didn't trust the church any more.
He Discovered that Earth was not the center of the solar system , Jupiter Has four moons and Venus has a face like a moon!! He also discovered the rings of Saturn. all this he just use one telescope?
Scientific advances in astronomy, medicine, and other conflicts continue to have great effects on the way we live and face the world.
This particular universe is discovered through direct observation. Knowledge about the universe continues to expand on many frontiers including particle physics which exploits equipment such as colliders to increase the understanding of properties of matter; astronomy contributes through land and space-based telescopes, manned spacecraft and unmanned probes and landers. Galileo, the 16th-century scientist, and known as the father of observational astronomy, provided a great example in discovery by practicing a pure form of science: he looked through a telescope and wrote notes about what he saw.
