Although, Galileo did not invent the telescope, he is thought as the inventor of the telescope. Hans Lippershey was the person who invented the telescope in 1608. Galileo learned about the spyglass in 1609. He thought that learning about spyglass was so exciting and interesting. His interest of the spyglass led him to the discovery of improving the telescope. In order to discover deeper, Galileo began to experiment with making the telescope and polished the lenses of his own telescope to increase the range about eight to nine times further. Due to Galileo’s improvement of his telescope’s range, he was the first person to discover sunspots, to see the moon’s craters, and to keep on track of the phases of

Galileo’s findings from his telescopic observations were revolutionary because he showed that the heavens were not perfect.

Dear Mr. Pope, My names is Ivan Cortes and the Scientist name is Galileo galilei his theory is that he was the first one to make a telescope to see the space and the moon and all the planted in space he found like mountain and valley and the surface of the moon and sunspot and the biggest moon ever also called as Jupiter and the phases of the planet Venus

God is known as the creator of Earth and one who knows everything. However, Galileo’s invention of the telescope has found things our leader did not inform us about Earth. Galileo believed earth was immobile and the sky was unchanging but his invention later proved otherwise. He discovered four moons around Jupiter proving that everything in our Universe did not circle the Earth. The telescope led him to see the rings of Saturn, phases of Venus, sunspots, and stars in the Milky Way.

In 1604, Galileo discovered a law of free fall, which anticipated Newton’s First Law. This marked the beginning of his study of the heavens. After constructing his telescope, with a magnification of twenty, he applied himself to the stars. It was through his telescope that he first postulated that the moon had mountains and valleys, just like earth, stating that “The false and inveterate idea that the heavenly bodies are devoid of all mutation and alteration…the inalterability of the sky…If ‘corruption’ and ‘generation’ are discovered in the moon, why deny them to the sky? ” He also claimed that the Milky Way consisted of innumerable stars, undermining the idea of a finite universe, and that Jupiter possessed its own moons, weakening the argument that all things revolved around the earth. Galileo also established that the sun contained moving sunspots, which undid the theory of the sun’s supposed perfection. The Church only

Sir Galileo Galilei was an Italian philosopher, physicist, mathematician, astronomer, and engineer. He is famously remembered for his several discoveries and inventions. In the year 1609, he first built his telescope which has been considerably valuable in studying and discovering what’s out there—outside this realm. He is most recognized for his examinations in January 1610, the four moons of the Jupiter which are named after him—Galilean moons. His telescope was 36.5 inches long and is a refracting telescope that collects visible light (Galileo's Refractor: The first telescope opens a window on the universe).

Galileo made many different discovers. They were the telescope, saturn's rings and that the moon has craters. There are many more. He made the telescope with two lenses almost like glasses. He used this to make most of his discovered. Another discovery he made was that the moon has craters. He used a telescope to find this out, but everyone thought he was crazy since the church says that god made everything perfect.

Throughout Galileo's lifetime, he has invented and inspected a couple of things that have changed our lives nowadays. After hearing about the telescope, Galileo structured one himself improving its magnification thirty-two times. After constructing his telescope, he was able to observe the moon and conclude that it has an uneven surface and monthly liberations. He also discovered four Jupiter moons, which are Io, Callisto, Ganymede, and Europa. In addition, he made inspections about sunspots, phases of Venus, and Saturn. Moreover, he perceived that the milky way is comprised of many stars. Ultimately, he wrote several books constituting all the consummations he did. Some of his books are the Sidereus Nuncius, The Assayer, Dialogue Concerning

The four massive moons of Jupiter were discovered by Galileo Galilei, around 1610 and they were the first group of objects found to orbit another planet. The names of these objects that were discovered by Galileo come from the lover of Zeus, the supreme god of the Olympians. These objects are among the largest objects in the Solar System with the exception of the sun and the eight other planets, with a radii larger than any of the planetary-mass objects that are neither a planet nor a natural satellite. Galileo's discovery of these moons showed that the telescope is an important tool for astronomers by proving that there were many objects in space that cannot be seen by the naked eye. Galileo named his discovery the Cosmica Sidera which is known as "Cosimos stars", but the names that eventually prevailed were chosen by Simon Marius. Simon Marius discovered the moons independently at the same time as Galileo, and gave them their present names. Galileo was able to know each and ones of the objects longitude based by timing of the orbits of the Galilean moons. The times of the eclipses of the moons could be calculated a little bit earlier, and were compared with local observations on land or on ship to determine the local time and hence of the longitude. But there was a main problem with this technique which was that it was too difficult to observe the Galilean moons through a telescope on a moving ship, and Galileo tried solving this problem with a device invented by himself called the celatone. Galileo Galilei has made many discoveries, but this discovery was prominently the best

Galileo’s observational discoveries in astronomy allowed for the basis to begin discrediting the old ideas in favor of a new understanding of the universe. The longstanding way of thought in astronomy favored a spherically rotating universe around the Earth with unchanging and perfectly symmetrical constellations and planets. The contemporaries of Galileo believed, for example, that the moon had the face of a shiny, polished sphere, whereas Galileo showed that the surface of the moon to be imperfect with rough mountainous areas along with deep valleys (or “seas” as he called them) marked with dark sports (Frova 162). This surface very much paralleled the rough surface of the Earth (meaning that Earth’s surface was not unique). Also with his improved telescope, Galileo was capable of viewing the stars with much more clarity. Galileo discovered newly formed stars and star clusters, which challenged the Aristotelian philosophy of an ageless universe. Additionally, Galileo observed four of Jupiter’s largest moons orbiting around the planet (Frova 179). His observations of Jupiter’s satellites did not agree with the idea that all heavenly bodies must rotate around a central Earth. Finally, and arguably most important, Galileo showed Venus’s phases and

Upon observing the moon for the first time through a telescope Galileo wrote,“Great indeed are the things which I propose for observation and consideration by all students of nature.” Galileo knew his discovery would impact the world but could not have known the magnitude in which it would affect everything known about astronomy. In The Starry Messenger, Galileo describes how he built and observed the moon through one of the first telescopes. His work not only perfectly and clearly reflects the time in which it was written but also shows how his discoveries related to the changing cultural norms. Without his curiosity and innovativeness astronomy would be nowhere near as advanced or influential.

Galileo’s greatest achievements were his work that backed up the Copernican Theory and his work creating the telescope famous. Galileo made the telescope famous because of the discovers he made with it. He built his own telescope which only had magnification of thirty times and was unpleasant to use but made some of the biggest discovers in the history of astronomy. He discovered that the sun was the centre of the solar system, not the earth as church believed which backed up what the Copernican Theory. Galileo was the first to discover that the moon was not flat and smooth but had craters, mountains and was a sphere. He was the first to discover that venus had phases similar to the moon. This greatly helped the Copernican Theory as it had

Galileo was first to have the use of a telescope to observe celestial bodies, which helped him greatly in making new discoveries. He was able to not only study the motion of other planets, but was able to observe the satellites orbiting those planets. Galileo also discovered an enormous amount of stars by observing the Milky Way giving way to theorizing that there is more to our universe then what was previously thought. Galileo later found himself in trouble with the Catholic Church for publicly announcing his findings, which went against the Church’s held beliefs of the Earth’s place in our universe. Sadly, Galileo had to essentially denounce his findings and was forced to keep his discoveries private for the rest of his days.

He also progressed the universal law of acceleration by finishing his theories on motion and falling objects (Galileo). After discovering the law of acceleration, Galileo began creating his own telescope. He built a telescope that could magnify at thirty power. When he turned his telescope to the sky, the things he discovered revolutionized astronomy. He saw the jagged edges on the moon, which he later realized were mountains. He was astonished when he turned his telescope to the Milky Way and observed that it was composed of many stars. He also observed the four moons of Jupiter and he even calculated how long it took them to make a full revolution (Galilei, n. pag). This was a phenomenal accomplishment for his time

In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”). Within
