Abstract
This paper looks at how life on Earth is defined, which stars are likely to have habitable planets, the possibility of extraterrestrial life, humanity's search for extraterrestrial life, and how astronomy is validated, updated and perfected by continuous astronomical research.

From the Paper
"The search for extraterrestrial life goes on, though so far none has been found. This does not mean it never existed or will not exist in the future. It may exist now, but in galaxies too far away from this one for us to detect. This paper will look at some of the methods being used to explore the universe and search for possible habitable planets and signs of extraterrestrial life. The properties of life on Earth differ depending on..."

Abstract
The paper explains that stars are set up to have planets circling around them and it is on those planets that scientists search to locate other life forms that may exist. The paper reveals that a growing body of scientists believe that there is/was life on Mars. The paper discusses how, with the advances in technology, it may not be long until we find a planet with living beings.

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."

Abstract
This paper discusses the Search for Extraterrestrial Intelligence (SETI) project and its search for extraterrestrial life via the capture and analysis of radio signals and use of cutting edge technology.

From the Paper
"Ever since ancient times, man has wondered about the existence of intelligent life on other planets. Speculation about what that life might be like has fueled the entire science fiction literary genre as well as a substantial number of movies, some of them excellent. Now, in the 21st Century, the search for extraterrestrial life has moved from the realm of science fiction into the realm of real science. New discoveries, new tools and cutting edge technologies have made the search for extraterrestrial life systematic, scholarly,..."

Abstract
This paper discusses what cultural aspects and other consequences would be of detecting extraterrestrial intelligent life. This paper will analyze the roles of the media, the government and the academic establishment that might be or should be played. The effect of sociology, politics and religion will be addressed.

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."

Abstract
Various governments and scientific institutions for over forty years have funded the search for extra-terrestrial intelligence (SETI). Continued public funding is currently under debate. This paper outlines the theoretical paradigm of SETI and current SETI research. It concludes by assessing the current state of the field and concludes that, while there is no evidence of extra-terrestrial intelligence (ETI), there is also no evidence against it. Therefore, it concludes, SETI research is an incredibly important and legitimate field of scientific inquiry that must be funded and pursued.

Abstract
The paper looks at how the constellations were described by the ancients, who saw patterns in the sky and saw these patterns as expressing their mythology. The paper asserts that because of the many centuries that have passed, many people see the stars as permanent and unchanging, but this is not true at all. The paper argues 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 paper points out that some changes do become more apparent, as when there is a supernova as a star reaches a crisis point and explodes into another form.

Abstract
This essay considers the traditional argument for pro-life choices which indicate to abort a fetus at any stage after conception is murder. By demonstrating that neither the pro-life or pro-choice can identify when personhodd starts, the paper states that there is always the potential for murder. Because life and personhood fall on a continuum, one cannot isolate its beginning and therefore any abortion is always a potential murder, something that is quite immoral from the start.

Abstract
This paper explores the experience of family members who are engaged in decision-making related to the withdrawal or withholding of life-sustaining interventions from another family member. It explains that the methodology used consists of a sample of four to five families who are contacted through ICU family conferences in one or two hospitals in which the conferences are concerned with the withholding or withdrawal of life support from a family member. The paper looks at how certain factors may be identified from family members' experiences that help to determine why the decision-making process is subject to wide variation.
The paper also notes that it is expected that certain family members engage in more effective decision making than others and that particular families engage in more effective decision making than other families. The paper highlights the fact that family decisions are rendered easier or more problematic by such variables as the person's prognosis, whether an acute or chronic illness is involved, perceived quality of life, degree of suffering, and the presence of an advance directive. The paper concludes that preparation for death most especially needs to be based in a team approach, and the emphasis should be upon the relationship between nurses and families and that the future needs of the family should be proactively considered once death has occurred.

From the Paper
"Nurses and other healthcare providers normally initiate the discussion that lead to withdrawal of life-support but patients and families make the final decision. The experience of decision making is different for family members when an acute illness is involved from a situation of chronic illness. After a period of denial, families of patients with acute illness or injury can recognize the need for withdrawal of support much more quickly (McHale Wiegand, 2006). Certain behaviors by healthcare providers can increase the level of distress experienced by the patient's family."

Abstract
This paper is a look in to the improbability of extra-terrestrial life. The writer discusses the nature of extra-terrestrial life, SETI's inability to find any intelligent messages, the improbability of life on other planets outside of our solar system, and the improbability of life on planets within our solar system. This paper is designed to deny the existence of extra-terrestrial life, not affirm it.

From the Paper
"The search for extraterrestrial life has piqued the interest of humans for ages. Scientists have long looked for it, and the U. S. Government funds many searches. However, the only reason that scientists have for their search is probability--there is no hard evidence to support a possibility of life, only supposition. The actuality of extraterrestrial life is minimal for three key reasons: the inability of SETI to find any significant sign of life after years of searching, the improbability of life on planets outside of our solar system, and the improbability of life within our solar system."
