Scientists have discovered a methane-rich tropical lake and several ponds near the equator of Saturn's largest moon Titan. Lakes were previously spied near Titan's polar regions but it was previously believed that bodies of liquid could not exist at Titan's midsection because energy from the sun at those latitudes would cause methane pools to evaporate. 'This discovery was completely unexpected because lakes are not stable at tropical latitudes,' said planetary scientist Caitlin Griffith of the University of Arizona, who led the discovery team. By measuring reflected sunlight from Titan's surface and atmosphere, the internationalCassini spacecraft detected a dark region near the landing site of Huygens, a companion probe that parachuted to Titan's equator in 2005.
