Starry Messenger

        In his book, Starry Messenger, published in 1610, Galileo wrote about his real important observations of the sky above. By use of a delve he made himself, improving greatly on the models available in his day, he was able to see things that could never in the beginning be seen. His telescope was far more right on than anything that had been uncommitted up to that point, and when coupled with his observational skills, proved to be a huge step forward in the guinea pig of astronomy.         By observing the stargaze, Galileo was able to see that the surface of the slug was non smooth or shaped as a guileless sphere like Aristotle thought it was. He noniced that the moon had some craters covering it, and even mountains. He made these observations by perusing the terminator of the moon. He noticed that origination was not suddenly straight like it would be if the moon was a utterly smooth sphere. In fact, there were many incons istencies in the line that proved that this was not the case.         Another big stripping he talks about in his book is that of Jovian satellites. By use of his telescope, Galileo was able to discover four satellites revolving well-nigh the orbiter Jupiter. He did this by observing four stars by Jupiter that he thought were interesting. They were precise small, but yet very bright.

For this fountain he kept watching them, and noticed their positions changing. This is how he observe that they were in fact satellites or Jupiter.         This discovery was not altogether important because new bodies had been discovered, but it also showed that the! landed acres was not the only center of rotation in our universe, which was the touristed view. This meant that our solar system was not geocentric, like Aristotle had thought it was. If you beggary to get a full essay, order it on our website: BestEssayCheap.com
