The giant body of ice orbiting Saturn may have more to offer than originally thought.
According to NASA, Saturn’s sixth-largest moon Enceladus may have a vast body of water underneath its surface.
They analysed pictures sent back by the Cassini probe over the course of seven years and detected a wobble on the icy crust.
That wobble would be explained by water beneath the surface rather than solid rock.
And, if water exists, there’s always the potential for alien life to be lurking on the moon.
“If the surface and core were rigidly connected, the core would provide so much dead weight that the wobble would be far smaller than we observe it to be,” said Matthew Tiscareno, a Cassini scientist based at the Seti (Search for Extra-Terrestrial Intelligence) Institute.
“This proves that there must be a global layer of liquid separating the surface from the core.”
Enceladus isn’t the only moon in the solar system that scientists believe contains water.
NASA is already planning a mission that will launch in the 2020s and explore giant lakes on Jupiter’s moon Europa.
NASA’s scientists are hoping this new mission will collect even more data on Europa and ultimately determine if it is habitable or not.
The mission will involve sending a solar-powered spaceraft into orbit around Jupiter that would then perform the flybys over a three-year period.
