Abstract
The paper describes how, through the ages, it has become evident that ancient civilizations had methods of creating structures that are unexplained, even to this day. The paper discusses how the manner in which astronomy affects archeology verifies this contention. The paper examines ancient observatories such as Chaco Canyon, Machu Picchu, and Chichen Itza, which have given science the means to explore the methods practiced by ancient societies in correlating the existence of their societies with the heavens.

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
This paper begins with a definition and description of the planets within our solar system and then goes on to discuss extra-solar planets and the ongoing search for them. The paper describes some of the technology and techniques employed in this search, a discovery of an extra-solar planet by scientists at the Geneva Observatory in Switzerland, and recent advances in locating extra-solar planetary objects.
From the Paper
"The word planet means "wanderer" in Greek. It derives from the fact that planets within our solar system seem generally to wander eastward about the so-called "fixed stars across the zodiac constellations (Kolb). There is no clear consensus precisely defining what constitutes a planet, as distinguished from brown dwarfs, which are the material remnants of burned out ancient stars whose masses where too small to form white dwarfs or collapse completely, forming black holes in the manner that stars much larger than ten solar masses, or ten times the mass of our sun (Hawking)."

Abstract
A look at the influence and impact of some African-American scientists and inventors - W. Lincoln Hawkins, who worked for Bell Labs; George Carruthers who developed the first moon-based space observatory; Elijah McCoy who developed for lubricating cup for firemen and many others.
From the Paper
"African Americans have been responsible for developing many life saving devices and processes in the field of medicine. The first inventor that we will mention is Charles Richard Drew. Many owe their lives to Dr. Drew and we see the results of his work every time we see a commercial for a Red Cross Blood drive. Dr. Drew pioneered the use of blood plasma in transfusions. He also co-founded one of the first U.S. Blood Banks and standardized international blood donation and storage.1 This process saved thousands of lives during WWII. Another African American in the field of Medicine was Dr. Patricia E. Bath of Los Angeles who patented the first apparatus that efficiently removes cataracts.2 More recently, Rufus J. Weaver patented a wheelchair that climbs stairs.3 "
