Blobs of warm ice that periodically rise to the surface and churn the icy crust on Saturn's moon Enceladus explain the quirky heat behavior and intriguing surface of the moon's south polar region, according to a new paper using data from NASA's Cassini spacecraft. "Cassini appears to have caught Enceladus in the middle of a burp," said Francis Nimmo, a planetary scientist at the University of California Santa Cruz and a co-author of the new paper in Nature Geoscience. "These tumultuous...

Planetary scientist Francis Nimmo will outline the impact of ice dynamics on the habitability of the moons of Saturn and Jupiter on Tuesday, December 15, at the annual meeting of the American Geophysical Union in San Francisco. Scientists once thought that life could originate only within a solar system's "habitable zone," where a planet would be neither too hot nor too cold for liquid water to exist on its surface. But according to Nimmo, a professor of Earth and planetary sciences at the...

NASA's Cassini spacecraft has sailed seamlessly through the Nov. 21 flyby of Saturn's moon Enceladus and started transmitting uncalibrated temperature data and images of the rippling terrain. These data and images will be processed and analyzed in the coming weeks. They will help scientists create the most-detailed-yet mosaic image of the southern part of the moon's Saturn-facing hemisphere and a contiguous thermal map of one of the intriguing "tiger stripe" features, with the highest...

Data collected during two close flybys of Saturn's moon Enceladus by NASA's Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water. The data collected by Cassini's Ion and Neutral Mass Spectrometer during Enceladus flybys in July and Oct. 2008, were released in the July 23 issue of the journal Nature. "When Cassini flew through the plume erupting from Enceladus on October 8 of last year, our spectrometer was able to sniff out many...

A new study has revealed the origins of tiger stripes and a subsurface ocean on Enceladus - one of Saturn's many moons. These geological features are believed to be the result of the moon's unusual chemical composition and not a hot core, shedding light on the evolution of planets and guiding future space exploration. Dr Dave Stegman, a Centenary Research Fellow in the School of Earth Sciences at the University of Melbourne, led the study and says that part of the intrigue with Enceladus is...

The Cassini mission, a joint venture of NASA and the European and Italian space agencies has been orbiting Saturn for five Earth years as of Tuesday. NASA officials said that is about one sixth of a Saturnian year -- enough time for the spacecraft to have observed seasonal changes on the planet, its moons and sunlight's angle on the dramatic rings. Cassini passed through a gap in the rings as it entered orbit on June 30, 2004, NASA said. It finished its prime mission in 2008 and continues to...

PASADENA, Calif., June 24 /PRNewswire-USNewswire/ -- For the first time, scientists working on NASA's Cassini mission have detected sodium salts in ice grains of Saturn's outermost ring. Detecting salty ice indicates that Saturn's moon Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water -- perhaps an ocean -- beneath its surface. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO ) Cassini discovered the...

Researchers in Europe released a new report on Wednesday that suggests the geyser seen on the surface of Saturn's moon Enceladus could be fed by a salty ocean underneath the surface. Writing in the journal Nature, scientists said that the discovery could support theories of the existence of extraterrestrial life. Scientists first discovered Enceladus' habit of spewing a mix of water vapor, gas and tiny grains of ice into space in 2005 with observations from the Cassini spacecraft. Enceladus...

The most exotic frozen cocktails on Earth won't be found in a chic restaurant or trendy bar. Scientists are mixing up these icy concoctions in a rather nondescript laboratory not much bigger than a janitor's closet. The surroundings are spartan, but the recipes they're using are out of this world. Researchers in JPL's Ice Physical Properties Laboratory are recreating the ices found on the frigid bodies that inhabit the cold, outer reaches of our solar system. The goal is to study up-close the...

Scientists believe that ice volcanoes observed on Saturn's moon Enceladus may stem from a sea beneath its surface, which could support theories for the existence of extraplanetary life. Since the Cassini spacecraft arrived on Saturn four years ago, scientists have been trying to determine what is causing Enceladus' volcanoes to spew ice. "What we have seen over the course of our travels has informed, moved and amazed us," planetary scientist Carolyn Porco, who heads Cassini's imaging team,...

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...
