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 …show more content…
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
