New research suggests the ocean underneath Saturn's moon Enceladus is global in nature.

Saturn's moon Enceladus likely contains a global ocean. 
Scientists analyzing images obtained from the Cassini mission have observed a noticeable wobble in Enceladus that they say only makes sense if its inner core is not directly connected to its outer shell. 
Using over seven years' worth of images, researchers were able to accurately determine the magnitude of the wobble and arrive at their conclusion.
Enceladus is home to what scientists call "tiger stripes"—large cracks in the moon's south pole where ice particles, salts, water vapor and o
