Life Beyond EarthVideo Cassette - 1999
Does life exist beyond Earth? It is an ancient question, one that has transfixed stargazers for centuries. Yet only in the last few decades have humans developed the tools to actively search for extraterrestrial life. Today astronomers are able to observe planets orbiting distant stars. Scientists are preparing probes to explore the farthest reaches of our universe, while others scan the heavens trying to detect radio signals sent by intelligent aliens. Some scientists predict that the discovery of life beyond Earth will occur before the end of the century. Whenever it comes, the discovery will be without parallel in its impact on human thought. "Life Beyond Earth," a two-hour science special, tells the story of humanity's search for life outside the confines of our own planet.
