Hints of fresh ice found in northern hemisphere of Saturn moon Enceladus

Scientists have found evidence that northern hemisphere of Saturn's moon Enceladus has been resurfaced with ice from its interior. Enceladus shoots out enormous plumes of ice grains and vapour from an ocean that lies under its crust. A global spectral map of Enceladus showed infrared signals that correlate with the geologic activity which is easily seen at the south pole.
