National Aeronautics and Space Administrion

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos. Check out our "Thinking About NASA History" folder online as an introduction to how history can help you.

Differing star catologs

Stars are found and put into order. However many of the stars are in more then one catolog as their catologs are similar. Now there are so far four catologs made up. The first catolog is NGC which.stands for the New General Catolog. The second one is known as UGC which is an abbreviation for Uppsala General Catalog. The next one is PGC which is Principle Galaxy Catolog. The last one is 2C which is the second Cambridge catolog of radio.sources.
