Saturn moon Titan may harbor ocean below surface
LOS ANGELES (AP) — Scientists reported Thursday on the strongest sign yet that Saturn's giant moon may have a salty ocean beneath its chilly surface.
If confirmed, it would catapult Titan into an elite class of solar system moons harboring water, an essential ingredient for life.
Titan boasts methane-filled seas at the poles and a possible lake near the equator. And it's long been speculated that Titan contains a hidden liquid layer, based on mathematical modeling and electric field measurements made by the Huygens spacecraft that landed on the surface in 2005.
The latest evidence is still indirect, but outside scientists said it's probably the best that can be obtained short of sending a spacecraft to drill into the surface — a costly endeavor that won't happen anytime soon.
The research looks convincing, said Gabriel Tobie of France's University of Nantes
