Record gasoline prices are raising the spectre of fuel shortages here on Earth, but there’s no energy crisis on Saturn’s largest moon, Titan. A paper in this week’s issue of Nature show’s that there is at least one very very big lake of liquid ethane on Titan. Scientists had already spotted lake-like features on the moon, but this is the first direct evidence of liquids on its surface.

Maybe it’s the fact that it’s liquid, or maybe it’s that ethane is an organic molecule, or maybe it’s just soaring fuel prices, but whatever the reason, this discovery’s been getting a lot of press.
