Even with a surface temperature of -180ºC, Saturn's moon, Titan, could be another Earth. It rains liquid methane from its icy cold skies. There's evidence of lakes filled this liquid methane. There are other surprising phenomena found on Titan's surface -- dunes made of enormous quantities of organic material that could contain the building blocks for DNA, as well as volcanoes that spew plumes of viscous "lava" composed of super-cooled water mixed with ammonia. Today, astrobiologists are conducting studies on the possibility that life could be present on Titan. This program reveals the latest findings about one of Saturn's most fascinating moons.

Countless stars illuminate the night sky. In our galaxy alone, there are over 100 billion stars. It's believed that immediately after the universe was created, there wasn't even a single star. There was only darkness. The "First Stars" that sparkled in space ended this Dark Age. Recent research has revealed that these stars dramatically changed the nature of the universe. The universe, as we know it now, with galaxies, planets and life, was created by these great stars. Get ready for new revelations about the first stars.
