Saturn Does The Wave In Upper Atmosphere
Pasadena CA (JPL) May 08, 2008Two decades of scrutinizing Saturn are finally paying off, as scientists have discovered a wave pattern, or oscillation, in Saturn's atmosphere only visible from Earth every 15 years. The discovery of the wave pattern is the result of a 22-year campaign observing Saturn from Earth (the longest study of temperature outside Earth ever recorded), and the Cassini spacecraft's observations of ... more A Glorious Saturn Steps Into The Spotlight In New York City 
New York NY (SPX) May 06, 2008In the four years since NASA's Cassini-Huygens spacecraft arrived at Saturn and began snapping pictures, Cassini's cameras have sent nearly 140,000 images back to researchers on Earth. The data and images -- as well as data from infrared, radar and ultraviolet detectors on the orbiter and images from the Huygens probe on the surface of the planet's moon Titan -- have given researchers ... more Titan's Smoggy Sand Grains 
Pasadena CA (SPX) May 05, 2008Titan and Earth have much in common, but not when it comes to sand. On Earth, sand grains form by breaking things down, but on Titan, the opposite may be true - with much of the sand a product of building things up. That's one theory Cassini scientists are considering after studying Titan's massive sand dunes with the visible and infrared mapping spectrometer on the Cassini Saturn orbiter. ... more NASA Spacecraft Tracks Raging Saturn Storm 
Pasadena CA (SPX) Apr 30, 2008As a powerful electrical storm rages on Saturn with lightning bolts 10,000 times more powerful than those found on Earth, the Cassini spacecraft continues its five-month watch over the dramatic events. Scientists with NASA's Cassini-Huygens mission have been tracking the visibly bright, lightning-generating storm--the longest continually observed electrical storm ever monitored by Cassini. ... more Saturn Images Showcased In New York City 
Pasadena CA (SPX) Apr 22, 2008A selection of the best images from Saturn, its rings and moons will appear in an exhibition opening on April 26 at the American Museum of Natural History in New York City. The show, called "Saturn: Images from the Cassini-Huygens Mission," will run through March 29, 2009. It features dramatic, up-close-and-personal images in small individual views and super-large mosaics. Roughly 50 image ... more |

Pasadena CA (SPX) Mar 20, 2008NASA's Cassini spacecraft has discovered evidence that points to the existence of an underground ocean of water and ammonia on Saturn's moon Titan. The findings made using radar measurements of Titan's rotation will appear in the March 21 issue of the journal Science. "With its organic dunes, lakes, channels and mountains, Titan has one of the most varied, active and Earth-like surfaces in ... more The Vanishing Rings Of Saturn 
Washington DC (SPX) Mar 19, 2008Saturn: jewel of the solar system, taker of breaths, ringed beauty. Even veteran astronomers can't help but gasp when they see her through a small telescope. Red Alert: Saturn's rings are vanishing. Around the world, amateur astronomers have noticed the change; Saturn's wide open rings are rapidly narrowing into a thin line. Four hundred years ago, the same phenomenon puzzled Galileo. ... more Cassini Spacecraft To Dive Into Water Plume Of Saturn Moon 
Pasadena CA (SPX) Mar 11, 2008NASA's Cassini spacecraft will make an unprecedented "in your face" flyby of Saturn's moon Enceladus on Wed., March 12. The spacecraft, orchestrating its closest approach to date, will skirt along the edges of huge Old-Faithful-like geysers erupting from giant fractures on the south pole of Enceladus. Cassini will sample scientifically valuable water-ice, dust and gas in the plume. The ... more Saturn Moon Rhea Also May Have Rings 
Pasadena CA (JPL) Mar 07, 2008NASA's Cassini spacecraft has found evidence of material orbiting Rhea, Saturn's second largest moon. This is the first time rings may have been found around a moon. A broad debris disk and at least one ring appear to have been detected by a suite of six instruments on Cassini specifically designed to study the atmospheres and particles around Saturn and its moons. "Until now, only planet ... more High Energy Electron Holes Reveal Unseen Rings 
Pasadena CA (SPX) Feb 26, 2008Gaps in the soup of high energy particles near the orbits of two of Saturn's tiny moons indicate that Saturn may be surrounded by undiscovered, near-invisible partial rings. A paper in the February issue of the journal Icarus suggests the larger Saturnian moons may not be the only ones contributing material to Saturn's ring system. A team of scientists has detected two peculiar breaks in ... more |

Paris (AFP) Feb 6, 2008Astrophysicists in Germany say they can add evidence to bolster theories that water, one of the precious ingredients for life, exists on the Saturnian moon Enceladus. A tiny satellite measuring just 504 kilometres (315 miles) across, Enceladus has become one of the most fiercely debated objects in the Solar System, thanks to close-up pictures taken by the US probe Cassini. Enceladus has ... more The Giant Sponge Of Saturn 
Pasadena CA (JPL) Feb 06, 2008One of Saturn's rings does housecleaning, soaking up material gushing from the fountains on Saturn's tiny ice moon Enceladus, according to new observations from the Cassini spacecraft. "Saturn's A-ring and Enceladus are separated by 100,000 kilometers (62,000 miles), yet there's a physical connection between the two," says Dr. William Farrell of NASA's Goddard Space Flight Center in Greenbelt ... more Oscillations found in Saturn's rings 
Stanford, Calif. (UPI) Jan 16, 2008 U.S. scientists have found evidence of periodic variation in the density of particles in some of Saturn's outer rings. The findings were made by instruments aboard the Cassini spacecraft in a series of experiments exploring the structure of Saturn's rings, and measuring the size and distribution of particles in the rings. The Cassini spacecraft flew behind the plane of rings A an ... more Cassini Image Contest Brings Nearby World Together In Search Of Beauty Beyond 
Boulder CO (SPX) Jan 10, 2008Thousands of enthusiastic fans of NASA's Saturn-orbiting Cassini spacecraft have chosen a color picture of a tiny, dot-like planet Earth, cradled by Saturn's rings during a total solar eclipse, as the most popular image of all those so far returned by the Cassini mission. People from across the globe visited the official website of Cassini's Imaging Team, during the month of December to vo ... more Radar Images Titan's South Pole 
Pasadena CA (SPX) Jan 09, 2008This synthetic aperture radar image was obtained by the Cassini spacecraft on its recent pass by Titan's south pole on Dec. 20, 2007. This portion of the (T39) swath is of the region extending from about 84 degrees south to the south pole, with a length of approximately 760 kilometers (470 miles) and width of 150 to 170 kilometers (90 to 100 miles). The polar projection of this image is at ... more
