Importance Of Telescope

Good Essays
After four hundred years of its invention, it became an important scientific instrument, a symbol of science. All through the 400 years history, this invention changed our view of the universe, our thoughts, societies and even our thoughts. This incredible scientific instrument has been built by the famous astronomer and philosopher from Pisa, Galileo Galilei. This invention can make far objects appear closer when viewed through one end of its long pipe. It was a telescope. The telescope’s iconic value is suitable. It was earth-shaking in its day and continues to be so today.

In august of 1609, four hundred years ago, there was a math professor from the University of Padua in Italy called Galileo Galilei. He changed and transformed the world

Galileo made a countless number of amazing discoveries when he pointed his telescope up to the sky. The most important and revolutionary discovery was that all planets rotated around the Sun, not our Earth, which had been the widely held theory until then and he challenged the Catholic Church's for this. This discovery created and spread a huge fuss between the people who followed the ancient belief of Greek and Egyptian proto-scientists that the Earth was the center of the universe and that the planets revolved around it, and those who followed the Copernican theory that in fact our Earth is just one of a number of planets revolving around the sun not the way around. [3] This is the major change the telescope made in history. Another great significance was denying the Aristotelian principles, which illustrates that the Moon is above the sub-lunary sphere and it’s in the heavens, therefore it should be flawless. Galileo noticed through his telescope that the moon’s surface is like the surface of the earth, not smooth and perfectly spherical, uneven, rough and crowded with bulges and it’s full of mountains chains and depths of valleys. Rotating it towards Jupiter, the remarks of the planet Jupiter exposed four star-like objects in a line with it. The objects moved and sometimes disappeared behind or in front of the planet. Galileo then concluded that these objects were Jupiter’s moons and it orbited it just like Earth. This was the first time that objects orbiting other planet than earth had been noticed, and this weakened Ptolemaic model. Today these four moons are known as the Galilean satellites; Io, Europa, Ganymede and Callisto. [4] In addition, Galileo presented the first primal mapping of the major stars of Earth's galaxy, the Milky Way. Based on brightness only, he mapped the largest stars into seven concentric circles which he called "magnitudes." Also, Galileo reached to the conclusion by observing the

    Hilliam says, “Isaac Newton combined laws of motions with his theory of gravitation to predict exactly how the planets orbit the Sun” (100). Newton’s law of gravity states that every object fall to the ground at the same speed. Even though Galileo had accomplished many things for science, “Galileo believed that his most important scientific contribution was his application of mathematics to the study of motion…” (Whitehouse 216). Galileo made many things possible for future scientists and astronomers. But many scientists and astronomers before Galileo made it possible for him as well.…

    Basically almost everything is held by gravity in space. Some astronomers believe some galaxies as held by black holes. But is that really the case? The short period of growth of the universe started of as the Big Bang about 13.7 billion years ago. After the Big Bang the universe started to cool of, starting protons and neutrons, hydrogen, helium, lithium and more.…

    The theory tells tries to show that the moon and earth was together when they past through a black hole. When going through the black hole the moon and earth separated as they are today. The only flaw in that theory is that it wouldn't explain why the moon orbits the earth. The theory that is probably the most trustworthy is the Giant Impact Hypothesis. The Giant Impact Hypothesis is that when the earth was still forming around 4.5 billion years ago the moon hit the earth, at least now it is called the moon before this mars sized planetoids was called Theia.…

    Brahe would go on to mentor an assistant named Johannes Kepler, who came up with the three laws of planetary motion. Theses laws would establish a concrete explanation behind the harmony amongst the stars. One of the most groundbreaking Copernican astronomers, Galileo Galilei was the first stargazer to observe the heavens with a telescope. This was a monumental happening – craters and rocky terrain on the surface of the Moon; the moons of Jupiter; spots on the surface of the sun; the phases of Venus. These findings were detailed in 1610’s The Starry Messenger, and amazed astronomers around the world.…

    The first law says that a planet’s path goes around the sun. The other describes the speed of a planet. All in all, the study with Mars is vital to the astronomical advantages we have today. In conclusion, the Scientific Revolution was vital to the things that we have today, and Johannes Kepler was among the great minds in that time. His advances in astronomy and mathematics were quite vital to things as important as bifocals and as obscure as an explanation for depth perception.…

    Since they are so many interesting things to see and learn about the universe, astronomers actually go into become specialists in their field work. They mainly focus on star-forming, galaxies, planet , they even try to search for life on other planets. Now the history of astronomy goes way back to the Babylonians (1600 B.C.). They believed that the heavens had the power over all of earth 's existence. Astronomy has one of the most earliest written records of Abstromnimacal observation.…

    The Heliocentric model meaning “Sun-centered” (Andronik 8) is the model we use today. Around 1510, Copernicus started work on the Heliocentric theory of the universe, another thing that he stated was that the Sun is the closest star to the Earth than any other star. Copernicus was dead before his system was proven correct. Galileo proved that the Heliocentric system was correct because he saw the movement of Venus with his telescope. Copernicus said that the Earth revolves around the Sun and the moon revolves around the Earth.…

    According to Mr. Donahue in the footnote for Chapter 7, “Mars and Mercury are the only planets whose orbits differ enough from circles for that difference to have an effect observable by Brahe’s instruments. Mercury is too near the sun to afford reliable observations of its entire orbit. Therefore, only the observations of Mars could have led Kepler to his ‘new astronomy.’” As soon as he discovered that Mars orbits non-uniformly by sweeping out equal horizontal areas in equal periods of times, he realizes that the orbit of Mars can by no means be circular, but only be…

    Theorists claim that this is due to that fact that the Apollo mission pictures were taken on the Earth, and astronomers would be able to figure out that the photos were taken from Earth. So to fix this conspiracists claim that NASA had a studio where they filmed the moon missions, surrounded, with a giant black screen, or they altered the pictures and removed the stars. However, there is a logical explanation as to why there are no stars. The moon is made out of regolith that is about four-to-five kilometers deep. The regolith has an albedo rating, telling how much light is reflected, between seven and ten percent (“Theories”).…
