Saturn's moons Tethys and Dione are flinging great streams of particles into space, according to data from the Cassini mission to Saturn.
Saturn's largest and most densely packed ring is composed of tightly packed clumps of particles separated by nearly empty gaps, according to new findings from NASA's Cassini spacecraft.
Rubbing your hands together on a cold day generates a bit of heat, and the same process of frictional heating may be what powers the geysers jetting out from the surface of Saturn's moon Enceladus.
Saturn may be a giant gravitational clock, controlling the timing of eruptions on Enceladus.
Photogenic Saturn has now become a movie star. Astronomers have woven NASA Hubble Space Telescope images of Saturn, its rings, and several of its moons into three movies.
New Cassini research suggests eddies, or giant rotating storms, are the "engine" powering Saturn's jet stream winds.
An odd, six-sided, honeycomb-shaped feature circling the entire north pole of Saturn has captured the interest of scientists with NASA's Cassini mission.

In a David and Goliath story of Saturnian proportions, the little moon Enceladus is weighing down giant Saturn's magnetic field so much that the field is rotating slower than the planet.
Instruments on NASA's Cassini spacecraft have found evidence for seas, likely filled with liquid methane or ethane, in the high northern latitudes of Saturn's moon Titan.

An epic space mission and one of the founding fathers of the European space endeavor will be forever linked. NASA and European space officials are honoring Hubert Curien by naming the Huygens landing site on Saturn's largest moon, Titan, after him.
NASA's Cassini spacecraft has captured never-before-seen views of Saturn from perspectives high above and below the planet’s rings.
In celebration of the holiday season and the close of another remarkable year at the Saturnian frontier, the Imaging Team for NASA's Cassini mission is presenting a smorgasbord of Saturnian imagery.
The tallest mountains ever seen on Titan -- coated with layers of organic material and blanketed by clouds -- have been imaged by NASA's Cassini spacecraft.
Scientists with NASA's Cassini mission have spied a new, continuously changing feature that provides circumstantial evidence that a comet or asteroid recently collided with Saturn's innermost ring, the faint D ring.
Cassini scientists are on the trail of the missing moons of Saturn.
Saturn appears dressed to the nines, "wearing" a strand of "pearls" in a stunning infrared image from the Cassini spacecraft that showcases a meteorological phenomenon.
A new image of Saturn demonstrates a technique that creates a 'Chinese lantern' effect, showing Saturn's deep clouds silhouetted against the planet's warm, glowing interior.
