A Glimpse Of The Past Through The Astronomy Collection- Astronomy is the field of study of the universe beyond the earth, and it has seen great challenges in the past 5000 years. The earliest studies took place both in China and the Mid-East, where records indicate a distinction between the ecliptic and the celestial equator, while Greek astronomers identified the intersection points of the two giving the equinoxes. Pythagoras (585-495 B.C.) established a center for astronomical study in southern Italy around 530 B.C. and taught that the earth was a sphere, accounted for planetary motion, and believed that the earth and planets revolved around the sun, the heliocentric theory. This was a major turning point in astronomy in that until that time the most prevalent view was that the earth was the center of the then known universe. Unfortunately, the heliocentric model of the universe was rejected by the revered astronomer Hipparchus and the geocentric theory as refined by Ptolemy held center stage until first seriously challenged by Copernicus in 1543 A.D. Copernicus rightly saw that the sun was the center, and the planets revolved around it. But, there were two powerful detractions. First, and most importantly, the Church objected saying that it was heretical to place the sun as the center of the universe instead of man. And second, it was reasoned that if the earth actually moved around the sun then the stars should show evidence of parallax as the earth moved. This was very puzzling, even to Copernicus, but at that time in history the instruments used to test this theory were far too primitive, and no one could imagine how extremely distant the stars were. The invention of the telescope and Gallileo's use of it in 1608 changed the current thinking. By 1618 Kepler had proposed his three laws of planetary motion, resulting in dramatic predictions and verifications of planetary orbits. Isaac Newton's law of gravity allowed most of the pieces to fit together in a workable, predictable form. In 1887, in Cleveland, the Michelson-Morley experiment showed that the earth's motion in space has no effect upon the velocity of light coming to it, that the absolute motion of the earth is not measurable, and that light waves do not require a medium of transmission. These results opened up a whole new world in physics and ushered in the eventual Laws of Relativity by Einstein, that have been substantially confirmed through astronomical observations. An American, Benjamin Banneker, born near Ellicott’s Lower Mills, Md., in 1731, achieved fame as a compiler of almanacs and his work in Astronomy. He acquired his astronomical knowledge through self-teaching, aided by the loan of books by George Ellicott, a Quaker millowner. Great strides have been made in the expanding fields of the astronomy, and now observations are being made from space using the space shuttle using the Hubble Space Telescope and other space based devices. We live in a time when advances in astronomy seem to come on a daily basis, as the puzzle of the origin of the universe is relentlessly pursued.
