Scientists said it was an "unexpected" discovery: There's a liquid methane filled lake near the equator of Saturn's moon Titan.
Scientists had seen lakes on Titan before, but they didn't expect them near the equator because they believed the intensity of the sun at those latitudes would evaporate the liquid.
"This discovery was completely unexpected because lakes are not stable at tropical latitudes," planetary scientist Caitlin Griffith of the University of Arizona, who led the discovery team, told the AP.

French President Francois Hollande (right) with his companion, Valerie Trierweiler, in Tulle, southwestern France, on June 9. Hollande campaigned as a down-to-earth politician, the opposite of his scandal-prone predecessor, Nicolas Sarkozy.
Europe may be in major financial and political turmoil, but in France, it's a tweet that has the country in an uproar.
The political storm erupted Tuesday when first lady Valerie Trierweiler tweeted her support for a candidate running in Sunday's parliamentary elections.
That may sound harmless, but the candidate she encouraged is running to unseat prominent politician Segolene Royal, the former partner of President Francois Hollande and the mother of his four children.
