Abstract The paper uses scientific data to support the claim that based on what is known by astronomers both about black holes and about our galaxy. The author finds that the scenario of a growing black hole is unlikely and would have already been discovered by multiple laboratories that exist to monitor our skies. The writer continues with a forecast of defense for which scientists are prepared in the event of the threat of a black hole.
From the Paper "The Schwarzschild radius also helps marks the point at which the gravity is so great that no state of matter can withstand it. This distance falls at approximately a factor of twice the Schwarzschild radius; the exact value has not been determined. However, the effect of its gravity on distant orbiting objects remains unchanged. The gravity pull is determined as a force originating at and acting on the centers of the objects. When the star collapses into a black hole, its center of mass remains the same, thus having no effect on the orbiting objects."
Abstract This paper discusses one of the most important and nation altering events to occur in the 1960s, the Apollo astronaut program, specifically, Neil Armstrong and Buzz Aldren's successful walk on the moon on July 20, 1969. It analyzes how space flight stimulated the nation's growth in myriad ways. It looks at the many technological advances came from the Mercury and Apollo programs and beyond, from lightweight metal alloys to smaller and smaller computer guidance systems which eventually turned into desktop computers so extremely prevalent in the world today. It evaluates how if we had not gone to the moon, our lives today might be much different and so would many of our institutions. Space flight stimulated technological growth, national pride and the notion that we can still "reach for the stars."
From the Paper "First came the Mercury project, where America put men in space. On May 5, 1961, Major Alan Shepard, a Naval academy graduate and test pilot, climbed aboard the Freedom 7 capsule atop a Redstone rocket and became the first American in space. Shepard's flight was sub orbital and lasted only 15 minutes, but it showed America we could still be vital in the space race (which the Russians were winning at the moment), and it kindled spirit and passion in the minds of Americans. The Mercury program ran from 1958 to 1963, and satisfied all its objectives. The Gemini flights between 1965 and 1966 were designed to transition between the Mercury exercises and the Apollo moon missions. The Gemini flights were to teach us how maneuver a spacecraft by maneuvering it in orbit, rendezvousing in space, docking with other vehicles, perfecting methods of entering the atmosphere, and landing at a preselected point on land."
Abstract This paper discusses the nature, causes and effects and the technological and legal solutions to the increasing problem of the presence of space debris and junk in space. By relating the problem of space debris to a memorable current event, it informs the readers about the possible dangers that future space explorations might face if this problem will be left unsolved. It also looks how technological and legal solutions provide an implication that the problem of space debris are taken seriously by government and astronomical agencies because of the prevalence of mishaps and accidents that have been happening/occurring in space.

Conclusion
From the Paper "Space debris and junk can pose a tremendous danger to satellites and spacecrafts, whether these spacecrafts are manned or not. In a book entitled, ?Orbital Debris,? authored by the Commission on Engineering and Technical Systems, spacecrafts traveling in the lower Earth orbit, or LEO, are more susceptible to collide with smaller particles, with a one-millimeter diameter (CETS 1995 4). However, there is also a big chance that big-sized particles will collide with spacecrafts and satellites traveling along the LEO region. Collisions between spacecrafts and space junk usually happen in the LEO region because this particular region is highly-populated with space debris and junk. This is logical since most of the space programs and explorations that were conducted by nations on Earth are usually located in the nearest region away from the Earth, which is on the lower Earth orbit."
Abstract Graduate level paper that discusses theories of region and space in contemporary geographical thought, from both a physical and human perspective. Focuses on human element in the definition of space, and modern technological capabilities for changing space and redefining regions.
Abstract A 7-page historical survey of the bond of Astrology and Astronomy and how as the result of the scientific method that bond was broken and how both are still influencing us today.
Abstract In his book, Davies raises the really Big Questions like "What is life?" Davies goes on to state that "the origin of life remains a deep mystery." Davies' proposes that intelligent life could be relatively common in the universe. This book provides a solid overview of current knowledge and theory on extraterrestrial life.
Abstract Scientific discoveries and tools have changed our knowledge of the universe over the years. With astronomers past and present, we have learned about the planet Earth, our Sun, and the planets that surround. This paper details the history of astrology, prominent astronomers, and the solar system.
Abstract This paper examines and analyzes the feasibility of colonizing the moon. The discussion includes the kinds of technology colonists would need to establish a permanent presence on the Moon, what they would need to survive, and what commercial aspects would be involved.
Abstract The essay reveals that the argument primarily suggests the innate existence of ideas. Descartes employs his famous "dream argument" to argue that the idea of one's own existence proves the difference between objective and subjective reality.
Abstract This paper examines Black Holes. It commences with theoretical speculation about the link between galaxy formation and black holes. Proving the existence of black holes through the discovery of event horizons is also examined.
Abstract This paper examines Comet Halley. Comets have historically been associated with danger, catastrophe and astrology. However, from the discovery of their periodicity three centuries ago to the Giotto expedition that intercepted the last apparition of the Comet Halley (A1) in 1986 provide valuable astronomical data.
Abstract This paper examines open star clusters. Open star clusters offer insight into the distances to galaxies and the age of the universe. The most recent research suggests the universe is 13.7 billion years old.
Abstract This paper examines recent developments in understanding of and research into Mars with the emphasis on the Canadian role. This includes excellent observation in the summer of 2003 and involvement in the Mars exploration program.
Abstract This paper examines the astronomical phenomenon of Aurora, more specifically the aurora borealis commonly known as northern lights. This essay examines the scientific understanding of their origins, the colors and images that result and concludes with consideration of the mythical and aesthetic links to the northern lights.
Abstract This paper examines the historic megalith in England known as Stonehenge. It focuses on archaeoastronomy and the astronomical influences on the design of Stonehenge.
