This video should be of interest to anyone who has a fascination with extraterrestrials and other worlds. If you have about 45 minutes of free time, I highly recommend watching this documentary. Enjoy.

You may also be interested in SETI@Home, a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.
