Introduction
Stars
The Search For Life
Conclusion
From the Paper "Man has been working on science since the beginning of time. As the human race continues to evolve, technology become more advanced and the ability to answer questions accurately grows stronger. One of the questions that has continued to stump mankind since the beginning of time is whether or not there is life out there. Songs are written about it, movies depicting aliens abound and books convey the belief that there is life on other planets and in other solar systems, however, to date no scientific evidence has been found that can support that belief. The technological advances that have occurred in recent history have allowed man to provide a more structured research setting to answer the questions about life bearing planets and alien life."

The Origins of Life, 2008. Looks at the origins of life on earth and the implications for the search for extraterrestrial life. 2,010 words (approx. 8.0 pages), 9 sources, APA, $ 63.95 »
Click here to show/hide summary
Abstract This paper explains that the search for life beyond this planet must be built on a solid understanding of how life managed to emerge on Earth. The author examines the development of extraterrestrial theories about the origins of life by beginning with an examination of previous theories of origin. The paper then presents current research and the empirical basis for current theories with implications for the search for extraterrestrial life. The author also offers some possible avenues of future research and examination, which could help refine the understanding of the origins of life in the universe.
From the Paper "In fact, the presence of a liquid like water seems to be the only major prerequisite for the development of life. Without a liquid, the complex chemical reactions required for the emergence of life are presumed impossible. But, that's not to say that the liquid in question must be water. Many researchers are exploring the possibility of life developing in more unorthodox liquids, such as methane, ammonia, or even sulfuric acid. Life on earth may have simply developed to take advantage of the very abundant liquid water; water's presence may have only been happenstance."

The Life Cycle of Stars, 2006. An analysis of the regeneration of stars. 1,118 words (approx. 4.5 pages), 2 sources, MLA, $ 38.95 »
Click here to show/hide summary
Abstract In order to shed some light onthe processes involved in the stars' life cycle, this paper discusses and analyzes how, throughout its 'life,' a star will remain dependent on other stars for its eventual re-birth--that is, the creation of another kind of a star. In line with the main topic of this paper, the discussion and analysis argue that the life cycle of a star is an interdependent and recurring process, mainly because stars depend on other stars to re-generate or create another star.
From the Paper "The second phase, the star's death, occurs when the star has finally used up its hydrogen atoms, and can no longer generate energy from its stellar body. As this happens, the star is "pulled" by the gravity and will burn its helium to become carbon, becoming a red giant. The dying star will be pulled towards the gravity because it will no longer have the counterforce that it once had (force from the energy radiated from it) in order to balance the two forces (gravity and energy pressure). Once helium gases were burned out or exhausted from the stellar body, carbon will be produced and scattered. The dead star will eventually have a carbon core, cool down, and become a white dwarf."

Formation of Stars, 2002. An analysis of the processes involved in the formation of stars. 1,541 words (approx. 6.2 pages), 3 sources, MLA, $ 50.95 »
Click here to show/hide summary
Abstract This paper explains that by viewing the gas that surrounds stars as a dynamic atmosphere, undergoing cycles of materials similar to those that go on in the Earth's own protective gases, astronomers are understanding more and more about the processes involved in the formation of stars. The paper deals with the questions of how the supernova of massive stars affect the formation of stars in the future, why star formation seems to occur in relative bursts, and how long the Milky Way will continue to produce stars.
From the Paper "Beyond applying the atmospheric model to intergalactic gas, astronomers have also been studying more carefully exactly what components make up the gas and at what temperature these components exist. About 90% of the constituents of intergalactic atmosphere are various forms of hydrogen, with close to 10% being helium, and everything else, from lithium to uranium -- the whole spectrum of the periodic chart -- making up less than 0.1%. The majority of the hydrogen is present as neutral hydrogen, termed H I by astronomers. This form of hydrogen gas is identified by the spectral frequency of the light that it emits, namely 1,420 megahertz. Although scattered throughout the galaxy, the majority of H I is located around the galactic midplane, and forms a gaseous disk about 300 parsecs thick (Reynolds, 2002, p. 40)."

Life Cycle of Stars, 2008. This paper describes the life cycle of stars, which is a normal progression. 1,185 words (approx. 4.7 pages), 4 sources, APA, $ 40.95 »
Click here to show/hide summary
Abstract This paper explains that stars have a life cycle that is simply too long for human life to perceive directly and even too long for all of human history to record. The author points out that astronomers have been able to categorize stars to show the different levels of development reached by different groups of stars. The paper relates that, over billions of years, the star slowly contracts, compensating for the heat and light energy it has lost. The author underscores that, as this contraction continues, the temperature, density and pressure at the core of the star increases. The paper tells that, as the temperature at the core rises and the star contracts, the tension between gravity pulling in and gas pressure pushing out determines the life of the star. The author describes this process through the star's life cycle from protostar to black holes.
From the Paper "At this stage, the star is called a planetary nebula. The core of this star becomes a whiter dwarf, an extremely dense star now the size of a planet. Once the white dwarf uses all its energy, it stops shining and becomes a "black dwarf," or a dead star. Astronomers see this as the final stage for our own Sun. however, for stars with higher masses than the Sun (up to about 40 times greater), the outer layers of the star may be thrown off with much more force in a supernova, an explosion leading to the collapse of the star down to a very compact size, producing what is known as a "neutron star."

Table of Contents:
A Summary of "Stars in the Making"
Relevance of "Stars in the Making"
A Critique of "Stars in the Making"
Suggested Changes to Harris' Article
From the Paper "In Harris' article, she makes the point that there are ways to mentor, motivate, and lead new salespeople to their full potential as salespeople; this point is cleverly proven by success stories from such luminary companies as Bausch & Lomb and others. Perhaps the most important message that Harris puts forth in "Stars in the Making" is that training, motivation and development of the skills needed for overcoming challenges are keys to the growth of salespeople over the long term. Because of this, Harris continues, sales managers must be coaches or mentors to their team members as well."

Aristotle's Astronomy, 2004. An analysis of Aristotle's astronomy. 1,174 words (approx. 4.7 pages), 4 sources, MLA, $ 40.95 »
Click here to show/hide summary
Abstract This paper presents a brief overview of Aristotle?s life and accomplishments. The paper examines Aristotle's education under Plato. The paper states that Aristotle had studied in depth and written about almost every subject that was in existence at the time, including anatomy, astronomy, physics, geology, zoology, aesthetics, rhetoric, logic, ethics, metaphysics, psychology, and literature. This paper focuses on his works regarding astronomy.
From the Paper "Aristotle (384-322 BCE) is one of the three most famous ancient philosophers whose work have left an indelible mark on the Western Civilization. Aristotle was born in Macedonia where his father was a physician in the royal court. He went to study in Plato?s Academy at the age of 17 where he stayed for 20 years and was Plato?s most distinguished pupil. After Plato died in 347 BC, he moved to Assos, a city in Asia Minor, and married the ruler (Hermias)?s adopted daughter. After Hermias? was captured and killed by the Persians a few years later, Aristotle was invited by the King of Macedonia to his court. There, he became a tutor to the King?s son Alexander?who was later to earn fame in history as Alexander the Great. In 335 BC, when Alexander became king, Aristotle returned to Athens and established his own school, the Lyceum. It was during the 13 years at Lyceum that most of Aristotle?s works were written. When Alexander the Great died in 325 BC, anti-Macedonian feelings in Athens forced Aristotle to retreat to a family estate in Euboea, where he died the following year."

Conclusion
From the Paper "The availability of spectroscopic software has allowed the possibility of quick and accurate study of quantum study of the spectral elements. GAMESS is one such software that can be used to calculate the SCF wave functions, perform automatic search for transition states, geometrical orientation and in analyzing the vibrational frequencies. GAMESS (General Atomic and Molecular Electronic Structure System) allows us to integrate quantum mechanics and molecular mechanics, which is essential for our understanding of the complex astronomical science. The software allows us to study chemical functions like dipole movements and to perform complex computations."

Tycho Brahe and 16th Century Astronomy, 2003. Examines the influence of Tycho Brahe on astronomy during the Renaissance. 2,364 words (approx. 9.5 pages), 15 sources, APA, $ 72.95 »
Click here to show/hide summary
Abstract Throughout the course of scientific inquiry, many great men and women have influenced scientific thought. Although their theories don't always agree with one another, their observations are important as they lead to further examination and observations of the natural world. During the great period of history known as the Renaissance, new insights into the universe and stars that surrounded the Earth influenced man's thought as to his position in the World. One such great scientist, an astronomer by the name of Tycho Brahe examined and observed the motions of the planets and stars during the Sixteenth Century. His theories of the Earth's position correspond with those of the religious and scientific ideas of the Renaissance. By studying his life, this paper shows how his method of analysis was influenced by the paradigms of scientific thought during the Renaissance. In addition, this paper shows that Brahe's observations influenced many astronomers and their research at that time and penetrated deeper to influence future astronomers in addition to scientists in other fields.
From the Paper "In early 1571, Brahe returned to his birth-home where he was called due to his father's illness. After his father died on May 9, 1571, Tycho shared a large inheritance and lordship with his elder brother. He didn't stay long, however, and soon moved to Herrevad where his uncle Steen promised to install a small observatory for Tycho17. On November 11, 1572, in this small observatory, Tycho discovered a new star in Cassiopeia. He continued to observe gradual changes of magnitude of this star during its appearance which lasted sixteen months18. Changing the paradigms of astronomical thought during the Sixteenth century, Tycho proved that it was not a meteor, but instead a real star which was within a region of fixed stars at the end of space."

Astronomy from Ptolemy to Galileo, 2005. This paper studies science, in particular astronomy, making use of the book "Science without Limits" by James Perlman. 675 words (approx. 2.7 pages), 1 source, $ 26.95 »
Click here to show/hide summary
Abstract This paper examines the history of science in terms of changes in astronomy from the time of Ptolemy to Galileo, based on the book "Science without Limits" by James Perlman. The writer notes how the ancients saw science as a form of philosophy, while by the time of Galileo, observation was being joined with experimentation to examine concepts and find the truth.
From the Paper "The history of astronomy shows the development of science as a discipline from the ancient world to the Renaissance, from the time of Ptolemy to the time of Galileo. Over that period, astronomy began to shift from a philosophy to a science. Science in the ancient world was not created out of whole cloth and was based on observations and the application of reason. Mathematics were also used to develop ideas about the universe. Mathematics is itself an application of reason, though aspects of mathematics have also been developed through observation and testing. By the time of Galileo, however, science was gaining a more experimental structure, and Galileo himself tested many ideas directly. His astronomy was also based on observations, but he was able to observe more directly and closely with the telescope. Perlman notes that "science in large part . . . is a matter of testing assumptions"."

Stars, 2007. An overview of the structure and characteristics of stars. 996 words (approx. 4.0 pages), 3 sources, MLA, $ 35.95 »
Click here to show/hide summary
Abstract This paper examines how a star is a huge, shining ball in space that produces a tremendous amount of light and other forms of energy. It looks at their physical makeup, the different types, and the recycling effect of star evolution on the rest of the universe.
From the Paper "Stars have many variants such as age, size, mass, and luminosity, but one thing they have in common is that "about 75 percent of all stars are members of a binary system, a pair of closely spaced stars that orbit each other" (Green, 2005, p. 1). Stars are also grouped together in galaxies such as the Milky Way which hosts more than 100 billion stars. "Three-dimensional computer models of star formation predict that the spinning clouds of dust may break up into two or three blobs; if true, this would explain why the majority of the stars in the Milky Way are paired or in groups of multiple stars" (science@nasa, p.1). Clearly, the structure and formation of individual stars mimics the structure of other important elements of the universe."
