Saturn has various moons orbiting around itself, but one of them seems to be sticking out more than others. In a Huffington Post article, “After carefully examining Mimas, we found it librates — that is, it subtly wobbles– around the moon’s polar axis,” Radwan Tajeddine, a Cornell research associate in astronomy and lead author of a new study in the journal Science said in a university news release.

These measurements allows scientists to indicate the satellite’s  insides. The wobble indicates there could be something lurking beneath the surface, possibly an ocean. Then again, maybe not: Tajeddine’s team believes a “weirdly shaped” rocky core could also produce the same wobbling effect. Could it be home to an underground body of water? If so, it would be lying about 15 to 18 miles underneath the moon’s surface.

But some scientists are already dismissing the theory.

“It’s really hard to understand how an ocean could survive for billions of years inside something as small as Mimas,” Francis Nimmo of the University of California, Santa Cruz, told New Scientist.

It will be extremely hard to us to tell whether or not there is an ocean underneath the moon. We don’t have to right technology or equipment to make the journey to Saturn. It would have to be a major priority to NASA for this to happen. Saying that, we will only be able to hear scientists’ opinions on this theory.
