From the Paper
"Cygnus A is the best known of the group of dumbbell galaxies. It consists of two nuclei in a common halo. It could be an extreme case of double galaxies. Galaxies are often radio sources.. Cygnus A is so-called because of the constellation in which it is located.. The galaxies at the center of radio star Cygnus A are photographed with the 200-inch telescope. These galaxies are practically at the limit of present optical observation. However, they are one of the strongest radio sources in the sky. Minkowski interprets Cygnus A as two galaxies, of about 100 billion stars each, in head-on collision - a catastrophe of tremendous magnitude. A different interpretation is that these two galaxies are the fragments of one original galaxy undergoing fission, that is, blowing apart in an explosion that must be just as violent as Minkowski's ...

Abstract
This paper is an in-depth treatise on the subject of black holes (it does not contain any sophisticated math). A black hole is a region of space where matters collapses in upon itself toward an infinite density, thereby endlessly increasing its mass and gravitational pull. It details the evidence for their existence both theoretical and empirical and describes the debates concerning their fundamental nature (how they warp time and gravity). It evaluates theories by Einstein and Stephen Hawking as well as related phenomenon such as white holes and wormholes.
From the Paper
"Man has always looked into the heavens and questioned the nature of the universe around him. Through the science of physics he has created such seemingly basic and ubiquitous concepts as time, mass, weight, and gravity. Held to be absolutes, these conceptual building blocks allow him to define, categorize, and relate the objects he discovers in the vastness of space. And without argument, his definitions and equations intercalating these abstractions hold true - except in one specific locus of space. A region of mystery possessing infinite depth yet of finite size, detectable in space yet emitting no electromagnetic radiation, an enigma of nature that beckons to be resolved. An entity first described as a ?frozen star? but then later dubbed a ?black hole? by John Archibald Wheeler. What is this black hole?"

Abstract
The paper looks at the Viking landing missions on Mars twenty years ago and their tests for biological processes on the Martian surface. It looks at how a recent series of orbiting Martian missions has yielded a good deal of chemical and geographic observations from afar. The most exciting possibilities have come from the analysis and interpretation of Martian surface formations seen by these missions. The paper includes a detailed description of these formations such as outflow channels, seepage gullies and several others. In further searches for definitive findings, several missions in the near future will land on Mars and hopefully provide the best data yet. This paper details some of the discoveries made to date, the strongest arguments for water on Mars and what the future holds for Martian exploration.
From the Paper
"The thought of life on Mars has intrigued humans for centuries. As Martian astronomy has made incredible leaps in the past 100 years and many spectacular discoveries have been made, we are still not sure if life does or has ever existed on Mars. Over the last thirty years, as our knowledge of biological functions has increased, scientists have focused more and more on the existence of liquid water as the biggest single indicator of possible life. To that end, much work and controversy has surrounded man?s efforts to find evidence of that all important ingredient for the development of life on Mars."

Galileo and Darwin, 2002.
A look at the discoveries of Galilei Galileo and Charles Darwin and the controversies surrounding their theories.

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 paper focuses on the history and the discovery of the nineth planet in the Solar System, Pluto, and its lone moon, Charon. The paper discusses various theories about what originally propelled astronomers to search for this mysterious planet, known as Planet X, and how its name Pluto finally came about after its discovery.
From the Paper
"John Murray, an astronomer from Open University in the U.K. proposes a theory in which two large objects may gravitationally affect the orbits of long period comets. These two objects would have to be about 32,000 AU from the Sun and extremely massive, about the size of Jupiter. John J. Matese of the University of Louisiana at Lafayette proposes a similar theory. His involves two to three Jupiter sized objects orbiting at about 2.3 trillion miles from the Sun. He says that their gravity is responsible for the deflection of roughly 25% of the known 82 Oort Cloud comets into the inner solar system. Matese says that these massive objects do not necessarily have to be planets; they may be undetected brown dwarfs ? undetected because the IRAS (Infrared Astronomical Satellite) of the 1980s was not sensitive enough to distinguish an individual brown dwarf against the galactic plane."

From the Paper
"Background
The Big Bang Theory is an explanation for the beginning of the universe. The universe today is expanding, as can be seen in the way all matter is moving outward. Tracing this movement back through time takes all matter to a single point, leading to the view that at one time all matter was concentrated in a singularity which for some unknown reason exploded, throwing all material now seen in the universe outward from that central point. There are various corollaries to this theory, such as the issue of whether the expanding universe will continue to expand forever or will eventually reach an end point and fall back on itself. There are also various consequences of the Big Bang which can be used to determine if the theory has validity. A number of researchers have examined aspects of the Big Bang theory and developed ideas..."

"Black Holes
Background
Many areas of astronomical research are inter related so that knowledge gained in one area causes a rethinking of other issues and provides evidence to solve old and new problems. One area of research that offers information useful to astronomers and physicists on many different issues is the search for black holes, an ongoing process that has been enhanced by the creation of the Hubble Space Telescope, and a central location for studying black holes is the Space Telescope Science Institute, the nerve center of the Hubble.
Black holes are theorized celestial bodies with a surface gravity so strong that nothing can escape from them, including light. If a star more massive than the Sun should undergo gravitational collapse at..."

"INTRODUCTION
People tend to believe all sorts of non-scientific and paranormal concepts and to accept this belief without proof. A prevalent belief is that aliens from some other cosmic body have visited the earth, though there is no direct proof of such an event. Many see this belief as deriving from the prevalence of science fiction in literature, films, and television and from anxiety brought about during the Cold War era, but in fact some belief in alien beings can be found throughout history, though identifying these interlopers as aliens from another planet is more common today than to see them as demons or emissaries from heaven or hell (even though many people believe in visitations from both these realms as well). Psychologists have considered the source of irrational beliefs of all sorts, including a belief ..."

"Mars Pathfinder - Generating Useful Data and Goodwill
The Mars Pathfinder Mission was an extremely successful venture, which has boosted the NASA Discovery Program and planet exploration in general. The data collected delivered some interesting surprises, but has contributed to our knowledge about the planet Mars and created basis for further study.
The Mars Pathfinder mission was the second launch in the NASA Discovery Program. Missions falling under this umbrella are of short duration, three years or less, and relatively low cost at 150 million dollars. The specific mission of the Mars Pathfinder was primarily to provide an engineering demonstration of the key technologies and concepts which will eventually be used in future missions. The mission was to demonstrate a low-..."

From the Paper
"The purpose of this research is to examine the phenomenon of supernovae. The plan of the research will be to set forth the context in which supernova observation and study have emerged in recent years, and then to discuss difficulties associated with supernova definition, study, and understanding, with reference to studies that have been undertaken regarding supernovas in general and the supernova known as SNV 1987A in particular.
On February 23, 1987, a truly cosmic event occurred--or more exactly was found to have occurred. Telescopes in New Zealand and Chile observed what was called the "brightest and closest" supernova to earth since "Kepler's supernova" in 1604 (Rensberger A7; Cowen 120). This was front-page news because telescopes had witnessed the event (marked by uncommon brightness), the historic proximity of the event to earth, and the fact that the initial ..."

"Manned Mission to Mars
Ever since the Sojourner began sending back video images from Mars, a renewed interest in the possibility of a manned mission to Mars has occurred. Such a plan as a mission to Mars raises all sorts of scientific, technical, and philosophical questions that this analysis will attempt to deal with. The main questions covered will be: 1) is there sufficient technology right now to handle such a mission? 2) is it important? 3) what kinds of data can it be expected will be returned? and 4) what are the problems of such a mission?
Is Technology Available
According the best data available, a manned mission to Mars is conceivable using the current technology resources available."

From the Paper
" Fluid Regulation in a Microgravity Environment
The extraterrestrial environment presents human beings with innumerable physiologic challenges. Astronauts engaged in space flight may experience alteration of their bodily fluids and electrolyte balance. Weightlessness generally causes a reduction in total fluid volume. In addition, there is typically a cephalad redistribution of the blood and other body fluids. This cephalad shift initiates a series of compensatory mechanisms, many of which involve hormonal fluctuations. Unfortunately, data collected from human subjects during actual space flight is rather scarce. This paucity has led to the use of various ground-based weightlessness simulations. Two important experimental techniques include the water immersion and bed rest methods. Unfortunately though, despite the considerable research.."

From the Paper
"Different cultures produce their own particular way of structuring the world they see around them. They use religion and ritual to explain, to gain control, and to express their own sense of connectedness to their environment. Pre-scientific societies develop their own mythologies to explain the origin of the universe and of human life. A comparison of three such societies shows how varied these ideas can be, with reference to the Maya, the ancient Chinese, and the Indians of the American southwest.
The New Text School in China was dominant throughout most of the Former Han dynasty and was given its name only later in apposition to the Old Text school, which rose to prominence in the time of Christ and gained ascendance through the Later Han dynasty. By "old" text the name means that the work was written..."

From the Paper
"For almost as long as people have studied the sky, the question of whether intelligent beings exist elsewhere has remained. Until recently, only conjecture and flights of imagination provided any answers at all.
Mars, being one of Earth's closer planetary neighbors, often evoked conjecture. In the 1890's the astronomer Percival Lowell misinterpreted the discoveries of a contemporary, Giovanni Schiaparelli, as canals cut into the Martian surface (Blazing a trail to Mars, 97). In 1922, Guglielmo Marconi used a radio receiver aboard his private yacht to listen for broadcasts from Mars (Shostak, 1995, 1). The search for extra terrestrial intelligence has widened considerably since then. Recent..."

Abstract
The paper defines black holes and explains what they are made up of. The paper explores common misconceptions surrounding black holes, as well as other mysteries. Finally the paper examines theories regarding how black holes eventually end.
From the Paper
"Black holes, one of space?s greatest phenomenons, appear to be tremendous concentrations of matter, usually at the center of a galaxy; however, smaller back holes are possible. The matter is in the form of neutrons, protons, and electrons, tightly packed together by their mutual gravitational attraction. The beautifully descriptive name comes from the fact that light cannot exit from a Black hole. They are suspected to form in the death and collapse of a star that began with more than10 times the sun's mass (those with less mass become white dwarfs or neutron stars)."
