'Methane-ologic Cycle'.

The article looks at the plan of researchers to use cameras on the Cassini Saturn probe to study the hydrocarbon rain and evaporation processes on the moon Titan. The cameras have spotted a cloud of organics over Titan's north pole on December 29, 2006. Scientists expected the cloud after discovering that the terrain below it is covered with lakes of liquid methane, ethane and other organics. Scientist Christophe Sotin said they were amazed by the size of the cloud formation.
