Abstract
This paper discusses the Hubble Space Telescope (HST), the first Earth-orbiting reflecting telescope. The paper examines how the Hubble Space Telescope serves a vital function in increasing our knowledge of the universe. The paper explains that since its launch in 1990, despite several crucial problems, it has revealed a universe full of mysterious bodies, nebula, star systems and galaxies and has expanded the possibilities that humankind is not alone in the universe.
From the Paper
"The first scientific idea for a telescope such as the HST came about in 1946 when Lyman Spitzer issued a proposal for a space telescope with a primary mirror between sixteen and fifty feet in diameter. Throughout the 1960's and 1970's, with the ultraviolet observatories OAO-2, OAO 3 and the IUE in the planning stages, the space telescope remained only a dream, due to the lack of technology. Yet Spitzer did not give up, for by the 1970's he had offered another proposal for a space telescope which would be able to provide images of very faint objects as contrasted to ground-based telescopes which suffer from distortion due to the Earth's atmosphere. According to Spitzer, such a telescope would not "supplement our present ideas of the universe we live in, but rather would uncover new phenomena not yet imagined and perhaps would modify profoundly our basic concepts of space and time" (42)."

Abstract
This paper discusses that there are many unanswered questions about the universe; therefore, there is a need for more powerful and better situated the telescopes as proposed by the Cornell University telescope at the Atacama desert in Chile where atmospheric conditions are superb. This paper explains that the astronomers and engineers at Cornell have devised a new design that they hope will provide more efficiency. The author points out that the new design allows the primary mirror to rotate in azimuth while a rotating Gregorian secondary mirror provides the primary mirror with a virtually unobstructed view of the source.
From the Paper
"Telescopes launched into outer space have captured public attention in recent years. The public may wonder at Cornell's choice to build a station on earth when advances seem to be in the sky with its advantage of greater 'height' and clearer view. It is true, of course, that observations at infrared and submillimeter wavelengths--such as the Atacama installation will perform--are far more easily made from space because of the absence of atmospheric interference. But, space stations are terrifically expensive, and the necessary limits on their telescopes' size places a huge constraint on their performance. Another important factor is that, in case of malfunctions, an earthbound telescope presents a great advantage. Thus, the search for optimal conditions on our planet has gone on for many years, and the Atacama Desert has become the astronomers' paradise of choice. The European Southern Observatory is already in operation there, and the United States' National Radio Astronomy Observatory will undoubtedly locate its new Millimeter Array there."

Abstract
The paper describes the origins of the telescope. It includes a brief history of the magnifying glass and the first spectacles from which the beginnings of the first telescope evolved. The writer discusses Galileo's part in the development of the telescope and explains the changes from the Galilean model through to the reflecting telescope developed in the mid 1700s. In summation, the paper explains that the telescope has led to other important inventions such as the microscope.
From the Paper
"The cost of quality glass had come done enough by the end of the thirteenth century and the quality was reasonable enough that it was becoming a real possibility for people to be aided in their eyesight problems as they reached their middle years. It was discovered by spectacle makers that they were able to enhance vision for people by shaping and polishing glass in such a way that the words were enlarged. This is what is known today as the magnifying glass and had become common by the middle of the thirteenth century. From here came the invention of the spectacles and as the glass lenses were made smaller and it was learnt what could be done by altering shapes and polishing the glass in various ways the beginnings of the telescope evolved."

From the Paper
"The Hubble Space Telescope is a cooperative program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) for the operation of a long lived space based observatory for the benefit of the international astronomical community. The idea was first developed in the 1940s, designed and built in the 1970s and 80s, and made operational only in the 1990s. This was to be a different type of mission for NASA, to create a long term space based observatory. In order to accomplish this goal and to protect the spacecraft against instrument and equipment failures, NASA had always planned on regular servicing missions. The Hubble has special grapple fixtures, 76 handholds, and is stabilized in all three axes. The Hubble is a 2.4 meter reflecting telescope which was deployed in low ..."

Abstract
A paper on the development of the telescope by Galileo Galilei. The author discusses the many theories borne from Galileo's observations of the heavens.
From the Paper
"Centuries ago, a tube and two lenses were the only essentials needed to start the journey into the sky. This instrument, called a telescope, expanded the human vision and brought new light from beyond their world and beyond the already visible sky. It allowed mankind to explore the most distant places imaginable without leaving their backyard. Astronomers have studied the stars for centuries, and, with the aid of a telescope, have discovered new entities that exist in the universe. The first person to use this tool for astronomical purposes was Galileo Galilei. He was the first to turn a telescope up into the stars and make observations. His telescope was crude and not as powerful as telescopes today, but it was effective during his time. Although modern telescopes are far more powerful and extremely effective due to electronics, mirrors, and other enhancements to the design of the telescope, the observations and discoveries made by Galileo and his rudimentary telescope are just as significant as those made by telescopes today and in the future."

Abstract
This paper is written about refraction and reflection images in telescopes. Refracting telescopes were the only type of telescope for nearly a hundred years" (Course Notes 36). In the refractor telescope, the objective lens is responsible for magnification. In reflector telescopes, it is the primary mirror that collects great amounts of light from distant objects and creates a brighter image.

Abstract
This paper compares the Hubble Space Telescope to its potential successor, the James Webb Space Telescope (JWST), in terms of their cost effectiveness. The paper looks at the technology of both telescopes to see which will bring continue to bring back the most valuable information, their respective missions, the cost of deploying and maintaining them in orbit, and the cost of repairs, if any, of the telescopes to determine the cost effectiveness of the telescopes.
From the Paper
"Ever since its launch in 1990, the Hubble telescope has been orbiting the Earth at 600 kilometers above, bringing valuable information and photos from space. Its history goes back to 1977, when the Congress approved the project funds. However, operations didn't take off until 1981, when the Space Telescope Science Institute was founded, designed especially for the production and research of the Hubble Space Telescope."

Abstract
This paper provides an overview of the Milky Way galaxy, named for the hazy band of light that stretches across the dark skies of the night. It looks at how, although this system (usually referred to as a spiral galaxy, much like the Andromeda galaxy) has created much wonder and awe since the beginning of human civilization, it was not until 1610 that its true nature was discovered by Galileo when he turned his small refracting telescope toward the night sky to reveal that the Milky Way was composed of countless individual stars, nebula and other astronomical bodies, many of which remained mysterious and unknown well into the 20th century.
From the Paper
"Looking from the Earth at the Milky Way, one obtains two distinct views--first, in the direction of the poles, the density of the stars decreases dramatically, meaning that at the poles, the stars are far apart and are set against a very dark background. Second, looking along the equatorial plane, the closest stars are situated against a faint but luminous band, being "the blended light of billions of stars in the galaxy's disc. In 1785, astronomer William Herschel, by using a 48-inch reflector telescope of his own construction, counted the stars in more than 600 regions of the sky and concluded that "the majority are concentrated along a plane and that the galaxy is disc-shaped with the Sun at its center" (Parker, 1988, 156).

Abstract
This paper details how Galileo Galilei affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church.
From the Paper
"Galileo Galilei was a mathematician, an astronomer, and a physicist who made several significant contributions to modern scientific thought. During his life, he made many scientific discoveries, often in contradiction with the centuries-old ideas of the Greek philosopher Aristotle. These contradictions led to great conflict with the Catholic Church; however, he emerged as a symbol to others who oppose unyielding authority and champion scientific progress. As James Reston's biography Galileo makes clear, Galileo is a historical figure who affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church."

Abstract
This paper looks at how, as Galileo first turned his telescope toward the heavens, he was drastically turning mankind away from its long-accepted view that the Aristotelian view of the heavens was correct. It examines the significance of Galileo's early astronomical observations on the Aristotelian universe by examining Aristotle's theory of the cosmos, pertinent background on Galileo, his discoveries, and the effect they had on Aristotle's universe.

Conclusion
From the Paper
"The next object Galileo turned his attention to was the planet Jupiter. In January of 1610, he saw three small but bright stars in the area of Jupiter that changed positions with time, but never strayed far from Jupiter. After repeated observations, Galileo concluded that there are three stars in the heavens moving about Jupiter. He later discovered a fourth satellite of Jupiter and he named these moons the Medicean stars. These satellites were seen to orbit Jupiter at various distances and speeds. This was the first time that a planet other than Earth was found to have satellites orbiting it."

Abstract
This paper begins by providing a brief biographical overview of Isaac Newton, from his birth in England in 1642 to his groundbreaking scientific theories and discoveries. The paper covers Newton's scientific achievements, starting with the fact that he established a unified theory of approach to modern science. It discusses his discoveries relating to the white light, the telescope and to the field of optics in general. The paper also covers Newton's mathematical achievements in the form of calculus and his most famous discovery of all - gravity.
From the Paper
"Newton's discoveries in optics were offset by his even more groundbreaking discoveries in pure mathematics and the science of mechanics. One of the most important modern mathematical tools 'The Integral Calculus' was the brainchild of Newton. It need not be mentioned that without this mathematical tool the progress that the scientific community achieved in many disciplines would have been significantly delayed. However Newton's discoveries in the field of mechanics outweigh all his other accomplishments. Though Galileo had already discovered the first law of motion his theory was based on the movement of objects without any external influence or attraction between them. Newton's three laws of motion explained the hitherto inexplicable behavior of all physical bodies in motion. Still more astounding was Newton's discovery of gravity. All these four laws put together explained the mechanical motion of all earthly and heavenly bodies. Newton not only proposed these laws but also ratified them by using the integral calculus."

Abstract
This paper examines the discoveries of two famous men, Galilei Galileo and Charles Darwin, and compares the way in which their respective ideas were accepted in their ages of discovery. It discusses how Galileo's discovery of the telescope and subsequent proving of the solar system's existence, led him to be branded as a heretic. The paper shows how Charles Darwin's 19th Century book "On the Origin of Species" also caused him to be labeled a heretic, especially when he related his theory to the evolution of man. The paper shows how both Galileo and Darwin undermined the Catholic church and in the face of enormous obstacles, eventually led people to accept their theories.
From the Paper
Galileo Galilei once said, " All truths are easy to understand once they are discovered; the point is to discover them." Contrary to his thoughts, however, all truths are not easy to understand, and some are even harder to sustain. Upon his development of the telescope in 1609 Galileo was able to present empirical evidence to prove Copernicus' heliocentric view of the solar system. Regardless of his evidence Galileo met the same fate as his precursor as his findings were cast aside and he was labeled as a heretic."

Abstract
This essay explores John F. Kennedy's inaugural address of 1961. It looks at the ways in which Kennedy's speech effected America and the world during the Age of Industrialization. Gauging history from the perspective of a refined hindsight telescope, this essay explains the relevance that Kennedy's speech had on the future course of globalization. The essay also highlights parts of Kennedy's address that relate to today's War on Terrorism.
From the Paper
"Kennedy, like Eisenhower before him, faced many obstacles in his search for allies. Initially, polycentrism posed a serious stumbling block for the cause of freedom. Just as there were many nations willing to align themselves with America in the fight for liberty, there were also a plethora of autonomous Communist movements that were spreading Communist ideals throughout Asia and the USSR. Kennedy also confronted problems of apathy and neutralism. Many nations denied the invitation to side with Democracy or Communism feeling that it was in the best interest of their respective nations to abstain from foreign involvement. This further delayed progress and globalization. Aggressive China, with her enormous population and dominant Asian influence, spread the seeds of Communism that grew to bite the heels of American soldiers throughout the long struggles of Vietnam. Kennedy's task was not an easy one. As president, Kennedy made countless attempts to ease conflict with Russia after the Cuban Missile Crisis. In spite of his attempts to ease tensions, Kennedy could not shrink from the fundamental principle of national restraint originally outlined in the Truman Doctrine."
