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.

And I'm Melissa Block. There's news today that the U.S. Anti-Doping Agency, or USADA, has brought formal doping charges against seven-time Tour de France winner Lance Armstrong. USADA is the body that fights performance-enhancing drug use in Olympic sports.
A NASA mission aimed at surveying black holes and supernovae, among other things, launched successfully today at noon ET from beneath the belly of a wide-body jet flying approximately 40,000 feet above a darkened Pacific Ocean.
The 772-pound NuSTAR X-ray observatory was carried into an equatorial orbit about 400 miles above the Earth by a Pegasus rocket, which fired its three-stage motor for 13 minutes after being dropped by the L-1011 jet.

But as a group they are reliably influential voters, more risk-averse than men, and — pollsters tell us — generally more likely than the opposite sex to vote for Democrats, oppose the use of military force and support government programs.
In 2008, unmarried women, one of the nation's fastest-growing demographic groups, were a key to Barack Obama's presidential win.
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.
