The mysterious icy jets erupting from Saturn's moon Enceladus may have their roots in a bubbly "Perrier ocean" flowing beneath the moon's frozen surface, a new study finds.
This salty subsurface sea could feed violent geysers on Enceladus, supplying them with water, gas, dust and heat before sinking back to the dark depths.
"The realization that there's a circulation system inside of Enceladus is something that's a new way of thinking," Dennis Matson, a researcher with NASA's Jet Propulsion Laboratory, told reporters Monday (Oct. 4). "But as you know, Enceladus has unique properties." [New photo of Enceladus geysers.]
