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.

SETI

On August 15, 1977 there was a signal that was heard from space. It was called the WOW signal. It was heard from a telescope of SETI. SETI stands for the Search for Extraterrestrial life. This program began in 1959.

The WOW signal was recieved by Dr. Jerry Herman from Ohio State University on the Big Ear Telescope. It was a 72 second radio transmission.

Now SETI is both a movement.as well as a group. Sagon Research Institute is just one of the sites. It was where the signal was recieved.

Stars suitable for life are found about 40 times a year, and 50% of these may in habit life as we know it. However, only 10% may have the ability of intelligent life.

There are three challenges for SETI. One is to organize itself. Two, is that there is a huge sky to cover and funding is low.  Three is the limit of light at separate times.
