Extraterrestrial Life -- From Fiction to Fact?

Synopsis
Extraterrestrial life was once considered to exist only in science fiction. But the latest advances in astronomy have debunked that view. Recently water vapor and ice particle jets have been discovered bursting out of the south pole of Saturn's moon Enceladus. These plumes are apparently erupting from underground reservoirs of liquid water, and they very likely contain micro-organisms. Gliese 581g, a planet that could have liquid oceans on its surface, has also been discovered 20 light years from Earth. Scientists have begun to closely investigate the environment of this planet for signs of life. Viewers will get an exciting look at the most advanced research into the possibility of extraterrestrial life.
