S1:E3 Visiting Saturn, Titan, Uranus, Neptune, and the Oort Cloud
First Aired: January 23, 1998
Runtime: 90 min
Today's imaginary journey into the cosmos targets Saturn, Uranus, Neptune, and Pluto, mysterious outer planets of the solar system millions of kilometers away from Earth. The NOOS astronauts visit Titan, traveling across its methane lakes in a special overcraft, and Miranda, Uranus's icy moon, carved by fractures and ravines. Their next stop, at the edge of the solar system, are the geysers of Triton and the Hoort Cloud: a cluster of approximately one hundred billion comets that seems to envelop the solar system like a shell. Alberto Angela is joining us from NASA's Exobiology Research Center, at El Tatio, 4,300 meters above sea level in the Andes, and from the Institute of Nuclear Physics in Frascati, Rome (where experiments are being conducted to reach absolute zero).
