WASHINGTON -- One of Saturn's moons is spraying icy particles into space from the area around its south pole, a sure sign of geologic activity, NASA reported on Tuesday. Recent images captured by the Cassini spacecraft reveal what looks at first like the narrow crescent shape of a solar eclipse, with plumes of particles being ejected from the Saturn moon Enceladus. "For planetary explorers like us, there is little that can compare to the sighting of activity on another solar system body,"...

By Paul Carrel PARIS (Reuters) - Saturn's moon Titan resembles Earth in many ways but is unlikely to support life, scientists said on Wednesday after almost a year of research into data from the space probe Huygens. After a seven-year trip from Earth piggy-backed on the Saturn probe Cassini, the European-designed Huygens separated last December and headed for Titan, entering the moon's atmosphere in January this year. "Huygens descended through a hazy, windy and turbulent atmosphere,"...

By Gideon Long LONDON (Reuters) - There is a hot spot on one of Saturn's moons which should not be there and has yet to be explained, scientists said on Tuesday. It is located at the south pole of Enceladus, a moon with a diameter of just 500 km (310 miles) which orbits Saturn at a distance of around 238,000 km. The hot spot is unusual because it occurs at the pole, scientists said. Usually, the hottest part of any planet or moon is around the equator, as is the case with the...

ESA -- Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn's majestic ring system has its own atmosphere - separate from that of the planet itself. During its close fly-bys of the ring system, instruments on Cassini have been able to determine that the environment around the rings is like an atmosphere, composed principally of molecular oxygen. This atmosphere is very similar to that of Jupiter's moons Europa and Ganymede. The finding was made by two instruments on...

New images of Saturn obtained by a University of Colorado at Boulder-led team on June 21 using an instrument on the Cassini spacecraft show auroral emissions at its poles similar to Earth's Northern Lights. Taken with the Ultraviolet Imaging Spectrograph aboard the Cassini orbiter, the two UV images, invisible to the human eye, are the first from the Cassini-Huygens mission to capture the entire "oval" of the auroral emissions at Saturn's south pole. They also show similar emissions at...

LOS ANGELES -- Scientists peering through a ground-based telescope say the surface of Saturn's planet-sized moon Titan appears dry and not awash in oceans of liquid hydrocarbons as is commonly believed. Titan - one of two moons in the solar system known to have a significant atmosphere - has long baffled scientists because it's surrounded by a thick blanket of nitrogen and methane. Scientists have speculated that the atmospheric methane probably came from seas of liquid methane and ethane....

JPL -- Saturn's tiny icy moon Enceladus, which ought to be cold and dead, instead displays evidence for active ice volcanism. NASA's Cassini spacecraft has found a huge cloud of water vapor over the moon's south pole, and warm fractures where evaporating ice probably supplies the vapor cloud. Cassini has also confirmed Enceladus is the major source of Saturn's largest ring, the E-ring. "Enceladus is the smallest body so far found that seems to have active volcanism," said Dr. Torrence...
