The backstory: In earlier work, study co-author Valéry Lainey, an astronomer at the Observatoire de Paris in France, and his colleagues described two possible explanations for Mimas' odd orbit.
The French-led team analyzed changes in Mimas’ orbit and rotation and reported Wednesday that a hidden ocean 12 to 18 miles (20 to 30 kilometers) beneath the frozen crust was more likely than an ...
By taking a closer look at Mimas' orbit, they were able to find evidence pointing to a hidden ocean and estimate its size and depth. WATCH: Ayshah looks back at Cassini's 20 years in space The ...
Data collected during Cassini flybys of Mimas intrigued astronomers. The moon takes a little more than 22 hours to orbit Saturn and is only about 115,000 miles (186,000 kilometers) from the planet.
