Saturn's moon Titan has long been a place of interest to astrobiologists, primarily because of its apparent similarities to the early Earth at the time life first started. A thick atmosphere composed primarily of nitrogen and abundant organic molecules (the ingredients of life as we know it) are among the important similarities between these two otherwise dissimilar planetary bodies.

Global warming could drastically alter Africa's southern sand dune systems, spreading desert-like conditions and destroying the livelihoods of hundreds of thousands of people before the end of the century, new research warns.

How old is Titan's surface? For years, Saturn's moon Titan was thought to have mastered the cosmetic surgery of the cosmos, with barely a mark or wrinkle to betray its true age. Close-up views provided by Cassini instruments show that Titan is nearly as flawless as it seems from a distance.

During its closest flyby of Titan on April 16, NASA's Cassini spacecraft detected some surprisingly complex organic molecules floating in its upper atmosphere. Specifically, the spacecraft's mass spectrometer picked up the presence of a variety of hydrocarbons, including ethane and even octane.

Saturn's largest and hazy moon, Titan, has a surface shaped largely by Earth-like processes of tectonics, erosion, winds, and perhaps volcanism. Titan, long held to be a frozen analog of early Earth, has liquid methane on its cold surface, unlike the water found on our home planet.

Jonathan Lunine, a professor of planetary science and physics at the University of Arizona's Lunar and Planetary Laboratory in Tucson, Arizona, is also an interdisciplinary scientist on the Cassini/Huygens mission. Lunine presented a lecture entitled "Titan: A Personal View after Cassini's first six months in Saturn orbit" at a NASA Astrobiology Director's Seminar on January 24, 2005. This edited transcript of the Director's Seminar is Part 1 of a 4-part series.

Cassini-Huygens supplied new evidence about why Titan has an atmosphere, making it unique among all solar system moons. Scientists can infer from Cassini-Huygens results that Titan has ammonia, said Jonathan I. Lunine, an interdisciplinary scientist for the European Space Agency\'s Huygens probe that landed on Titan last month.

As part of the Cassini Imaging team studying the atmosphere on Saturn, NASA's Anthony Del Genio explained in this part of his interview, how to make sense of a moon potentially making methane rain.
