ESA's Herschel space observatory has shown that water expelled from the moon Enceladus forms a giant torus of water vapor around Saturn. The discovery solves a 14-year mystery by identifying the source of the water in Saturn's upper atmosphere. Herschel's latest results mean that Enceladus is the only moon in the Solar System known to influence the chemical composition of its parent planet. Enceladus expels around 250 kg of water vapor every second, through a collection of jets from the south...

Scientists say they have found convincing evidence that Saturn's moon Enceladus has a large-scale subterranean saltwater ocean. The discovery was made using data collected during the Cassini-Huygens mission to Saturn. The plumes of shooting water vapor and tiny grains of ice into space were originally discovered emanating from Enceladus by the Cassini spacecraft in 2005. The researchers from the University of Heidelberg and University of Colorado said during three of Cassini's passes...

WASHINGTON, June 22, 2011 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has discovered the best evidence yet for a large-scale saltwater reservoir beneath the icy crust of Saturn's moon Enceladus. The data came from the spacecraft's direct analysis of salt-rich ice grains close to the jets ejected from the moon.

Data from NASA's Cassini spacecraft have revealed that Enceladus, one of Saturn's diminutive moons, is linked to Saturn by powerful electrical currents - beams of electrons that flow back and forth between the planet and moon. The finding is part of a paper published in Nature today. CAPS, one of the instruments on board Cassini which made the electron beam discovery, includes a electron sensor called CAPS-ELS "“ led by UCL (University College London). Since Cassini's arrival at Saturn...

PASADENA, Calif., April 20, 2011 /PRNewswire-USNewswire/ -- NASA is releasing the first images and sounds of an electrical connection between Saturn and one of its moons. The data collected by the agency's Cassini spacecraft enable scientists to improve their understanding of the complex web of interaction between the planet and its numerous moons. The results of the data analysis are published in the journals Nature and Geophysical Research Letters. (Logo:...

Heat output from the south polar region of Saturn's moon Enceladus is much greater than was previously thought possible, according to a new analysis of data collected by NASA's Cassini spacecraft. The study was published in the Journal of Geophysical Research on March 4. Data from Cassini's composite infrared spectrometer of Enceladus' south polar terrain, which is marked by linear fissures, indicate that the internal heat-generated power is about 15.8 gigawatts, approximately 2.6 times the...

NASA announced Tuesday that the Cassini spacecraft passed by and snapped images of several of Saturn's moons. The space agency said the Cassini spacecraft passed within 37,282 miles of Enceladus and 17,398 miles of Helene.  The spacecraft also shot an image of Mimas in front of Saturn's rings. NASA said that one of Cassini's images is looking at the famous jets erupting from the south polar terrain of Enceladus. The Cassini-Huygens mission is a cooperative project of NASA, the...

By Dauna Coulter - Science @ NASA For years researchers have been debating whether Enceladus, a tiny moon floating just outside Saturn's rings, is home to a vast underground ocean. Is it wet--or not? Now, new evidence is tipping the scales. Not only does Enceladus likely have an ocean, that ocean is probably fizzy like a soft drink and could be friendly to microbial life. The story begins in 2005 when NASA's Cassini probe flew past Enceladus for a close encounter. "Geophysicists expected this...

Saturn's icy moon Rhea might seem a strange place to look for clues to understanding the vast majestic rings encircling Saturn. But that's what NASA's Cassini spacecraft plans to do on its next flyby of Rhea. At closest approach, Cassini will pass within about 69 kilometers (43 miles) of the surface at 4:53 AM UTC on Tuesday, Jan. 11, which is 10:53 PM Pacific Time on Monday, Jan. 10. This flyby is the closest Cassini will get to the icy moon's surface. Rhea, Saturn's second largest moon, is...

On the heels of a successful close flyby of Saturn's moon Enceladus, NASA's Cassini spacecraft is returning images of Enceladus and the nearby moon Dione. Several pictures show Enceladus backlit, with the dark outline of the moon crowned by glowing jets from the south polar region. The images show several separate jets, or sets of jets, emanating from the fissures known as "tiger stripes." Scientists will use the images to pinpoint the jet source locations on the surface and learn more about...

Saturn's moon Dione -- Dione is a moon of Saturn discovered by Giovanni Cassini in 1684. It is composed primarily of water ice, but as the densest of Saturn's moons (aside from Titan, whose density is increased by gravitational compression) it must have a considerable fraction of denser material like silicate rock in its interior. Though somewhat smaller, Dione is otherwise very similar to Rhea. They both have similar compositions, albedo features and varied terrain. Both have dissimilar...

Saturn's moon Enceladus -- Enceladus is a moon of Saturn discovered in 1789 by William Herschel. At least five different types of terrain have been identified on Enceladus. In addition to craters there are smooth plains and extensive linear cracks and ridges. At least some of the surface is relatively young, probably less than 100 million years. This means that Enceladus must have been active very recently with some sort of "water volcanism" or other process that renews the surface....

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
