Because of Cassini, Enceladus is now one of the most consequential objects in the solar system. “The magnetic field lines were standing off from Enceladus’ surface, more like you’d see with a comet, but just at the south pole,” Spilker said. Through 2012 and 2013, Cassini scientists increasingly found a relationship between gravitational stress and changes in Enceladus’ jets. Researchers had been meticulously mapping positions of features on Enceladus’ surface using hundreds of photos from more than seven years of Cassini's mission. If limited to the south polar region of Enceladus, the moon’s ocean could be temporary, perhaps the result of a meteor strike.
