Enceladus Ocean Confirmed

Since 2005, scientists have suspected a huge ocean of water ice existed under the ice shell of Saturn's moon, Enceladus.  A new study confirms that, using slight variations in Enceladus' gravitational field to propose an ocean perhaps six miles deep exists under the southern hemisphere.

Further, the study suggests the ocean extends down to a rocky sea floor, increasing the possibility that life might exist there by expanding the range of possible chemical reactions.
