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...

Cassini performed back-to-back flybys of Saturn moons Tethys and Hyperion last weekend, coming closer than ever before to each of them. Tethys has a scarred, ancient surface, while Hyperion is a strange, spongy-looking body with dark-floored craters that speckle its surface. New images, mosaics and a movie of these bodies are available at http://ciclops.org, http://saturn.jpl.nasa.gov and http://www.nasa.gov/cassini. Images of Tethys taken during Cassini's close approach to the moon on Sept....

NASA -- Cassini performed back-to-back flybys of Saturn moons Tethys and Hyperion last weekend, coming closer than ever before to each of them. Tethys has a scarred, ancient surface, while Hyperion is a strange, spongy-looking body with dark-floored craters that speckle its surface. Images of Tethys taken during Cassini's close approach to the moon on Sept. 24, 2005, reveal an icy land of steep cliffs and craters. Cassini photographed the moon's south pole, a region not seen by NASA's...

Saturn's moon Tethys -- Tethys is a moon of Saturn that was discovered by Giovanni Cassini in 1684. Tethys is an icy body similar in nature to Dione and Rhea. The density of Tethys is 1.21 g/cm3, indicating that it is composed almost entirely of water-ice. Tethys's surface is heavily cratered and contains numerous cracks caused by faults in the ice. There are two different types of terrain found on Tethys, one composed of densely cratered regions and the other consisting of a dark...

toccata
  • 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.
