Signs of Ocean Beneath Titan's Crust?
NASA’s Cassini spacecraft has discovered evidence that points to the existence of an underground ocean of water and ammonia on Saturn’s moon Titan. The Cassini science team detail their findings in this week’s Science, explaining that radar mapping of Titan revealed a shift in landmarks on the moon’s surface of up to 30 kilometers between October 2004 and May 2007. The best explanation, they say, is an underground ocean...

Earth's Future Glimpsed on Titan
The enigmatic Saturnian moon Titan is still yielding surprising new details years after scientists first pierced its thick haze veil. The vision now emerging of Saturn’s largest moon, with its giant dunes and oceanless surface, is perhaps a glimpse of Earth’s desert future. Space.com has the story…

NASA's Cassini Spacecraft Images Seas on Titan
Instruments on NASA’s Cassini spacecraft have found evidence for seas, likely filled with liquid methane or ethane, in the high northern latitudes of Saturn’s moon Titan. One such feature is larger than any of the Great Lakes of North America and is about the same size as several seas on Earth.

Organic Hazes on Early Earth and Titan
Researchers from NAI’s Unviersity of Colorado, Boulder and University of Arizona Teams have published a new study in PNAS this week about the atmospheres of both present day Titan and early Earth. For Titan, their experiments modeled conditions measured by the Huygens probe from NASA’s Cassini mission, and CO2 was added to model the early Earth conditions. They conclude that organize haze can form over a wide range of methane and carbon dioxide concentrations.

NASA Study Shows Titan and Early Earth Atmospheres are Similar
Organic haze in the atmosphere of Saturn’s moon, Titan, is similar to haze in early Earth’s air — haze that may have helped nourish life on our planet— according to a NASA Astrobiology Institute study released Nov. 6, 2006.
