Titan’s surface organics surpass oil reserves on Earth

From the esa.int article:
Saturn’s orange moon Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth, according to new Cassini data. The hydrocarbons rain from the sky, collecting in vast deposits that form lakes and dunes.
 
The new findings from the study led by Ralph Lorenz, Cassini radar team member from the Johns Hopkins University Applied Physics Laboratory, USA, are reported in the 29 January 2008 issue of the Geophysical Research Letters.

“Titan is just covered in carbon-bearing material—it’s a giant factory of organic chemicals,” said Lorenz. “This vast carbon inventory is an important window into the geology and climate history of Titan.”

At a balmy minus 179º C , Titan is a far cry from Earth. Instead of water, liquid hydrocarbons in the form of methane and ethane are present on the moon’s surface, and tholins probably make up its dunes. The term ‘tholins’ was coined by Carl Sagan in 1979 to describe the complex organic molecules at the heart of prebiotic chemistry.
