NASA's Cassini spacecraft has detected a massive, never-before-seen icy cloud at the south pole of Saturn's huge moon Titan.
On Wednesday, NASA's Saturn-orbiting Cassini spacecraft will take a deep but quick plunge through plumes of water vapor shooting out hundreds of miles into space from the planet’s small, ocean-bearing moon Enceladus.
On Wednesday (Oct. 14), Cassini performed its scheduled “E-20” close pass of Enceladus, Saturn's icy moon that has become famous for the organics-laden geysers firing from long fissures along its southern pole.
Something is erasing craters on several moons of Saturn. What are the most likely causes?
The big moons of Jupiter may have oceans underground. Although they are driven by the same mechanism, their nature can be radically different.
By measuring tiny wobbles in Enceladus' orbit, scientists have figured out that Enceladus has a giant ocean.
