Four students have won the Cassini Scientist for a Day contest, with most choosing Rhea, Saturn's second-largest moon, as the best place for scientists to study using NASA's Cassini spacecraft.Contest participants had to choose one of three target areas for Cassini's camera: Saturn's moon Enceladus, Rhea, or a section of Saturn's rings that includes the tiny moon Pan. The students had to write an essay explaining why their chosen snapshot would yield the most scientific rewards, and the...

Curved features on Jupiter's moon Europa may indicate that its poles have wandered by almost 90°, report scientists from the Carnegie Institution, Lunar and Planetary Institute, and University of California, Santa Cruz in the 15 May issue of Nature. Such an extreme shift suggests the existence of an internal liquid ocean beneath the icy crust, which could help build the case for Europa as possible habitat for extraterrestrial life.The research team, which included Isamu Matsuyama of the...

A monster storm spawning bolts of lightning 10,000 times more powerful than any seen on Earth is raging on the ringed planet Saturn. The powerful electrical storm cropped up in Saturn's southern hemisphere five months ago, when it was first spotted by NASA's Cassini spacecraft, and has persevered to become the planet's longest continuously recorded tempest to date. "We saw similar storms in 2004 and 2006 that each lasted for nearly a month, but this storm is longer-lived by...

NEW YORK — Stunning images of Saturn and its moons will bring the ringed planet down to Earth for visitors at the American Museum of Natural History here starting Saturday. The new exhibition "Saturn: Images from the Cassini-Huygens Mission" offers just a sample of the more than 140,000 images beamed back to Earth across half a billion miles by NASA's Cassini spacecraft. Launched by NASA in 1997, Cassini became the first spacecraft to orbit Saturn in 2004. The international...

A 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 images taken by the Cassini-Huygens mission in visible light, infrared and radar have been hand-picked by a...

NASA is extending the international Cassini-Huygens mission by two years. The historic spacecraft's stunning discoveries and images have revolutionized our knowledge of Saturn and its moons. Cassini's mission originally had been scheduled to end in July 2008. The newly-announced two-year extension will include 60 additional orbits of Saturn and more flybys of its exotic moons. These will include 26 flybys of Titan, seven of Enceladus, and one each of Dione, Rhea and Helene. The extension also...

NASA will turn control of the Cassini spacecraft at Saturn over to students for a day in a contest aimed at boosting interest in science among today's youth. An essay contest for students in grades 5 through 12 will determine which of three science targets Cassini will photograph on June 10, the space agency announced late Thursday. Cassini scientists regularly debate exactly which images of Saturn's many moons and rings will produce the most science results, a task they are...

Could microbial life exist inside Enceladus, where no sunlight reaches, photosynthesis is impossible and no oxygen is available? To answer that question, we need look no farther than our own planet to find examples of the types of exotic ecosystems that could make life possible on Saturn's geyser moon. The answer appears to be, yes, it could be possible. It is this tantalizing potential that brings us back to Enceladus for further study. In recent years, life forms have been found on Earth...

PASADENA, Calif. -- NASA's Cassini spacecraft tasted and sampled a surprising organic brew erupting in geyser-like fashion from Saturn's moon Enceladus during a close flyby on March 12. Scientists are amazed that this tiny moon is so active, "hot" and brimming with water vapor and organic chemicals. New heat maps of the surface show higher temperatures than previously known in the south polar region, with hot tracks running the length of giant fissures. Additionally, scientists say the...

One of Saturn's moons may have been home to a body of water, according to scientists who reported their findings at the 39th Lunar and Planetary Science Conference in Houston.With a density similar to pure ice, researchers think that Tethys underwent tidal heating, followed by cooling which could have been responsible for forming the Ithaca Chasma.Erinna Chen and Francis Nimmo, from the University of California, Santa Cruz, proposed that it was Tethys' orbital interaction with Dione, another...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
