By Philip Haldiman, The Arizona Daily Star, Tucson Jul. 31--Our planet isn't the only heavenly body with liquid on its surface. Scientists from the University of Arizona and NASA on Wednesday announced at least one of the large, lakelike features on a moon of Saturn is wet.
NASA's Cassini spacecraft performed a daring flyby of Saturn's moon Enceladus, flying about 15 kilometers per second (32,000 mph) through icy water geyser-like jets. The spacecraft snatched up precious samples that might point to a water ocean or organics inside the little moon.
The formation of strange flying-saucer-shaped moons embedded in Saturn's rings have baffled scientists.
Imaging scientists on NASA's Cassini mission are telling a tale of how the small moons orbiting near the outer rings of Saturn came to be. The moons began as leftover shards from larger bodies that broke apart and filled out their "figures" with the debris that made the rings.
A recent analysis of images from NASA's Cassini spacecraft provides conclusive evidence that the jets of fine, icy particles spraying from Saturn's moon Enceladus originate from the hottest spots on the moon's "tiger stripe" fractures that straddle the moon's south polar region.
Scientists on the Cassini mission to Saturn are poring through hundreds of images returned from the Sept. 10 flyby of Saturn's two-toned moon Iapetus. Pictures returned late Tuesday and early Wednesday show the moon's yin and yang--a white hemisphere resembling snow, and the other as black as tar.
NASA's Cassini spacecraft has captured never-before-seen views of Saturn from perspectives high above and below the planet's rings. The spacecraft has climbed to higher and higher inclinations, providing its cameras with glimpses of the planet and rings that have scientists gushing.
New research casts doubt on the existence of water near the surface of a tiny Saturn moon â€” a finding that, if confirmed, could set back the hunt for extraterrestrial life.
Saturn sports a new ring in an image taken by NASA's Cassini spacecraft on Sunday, Sept. 17, during a one-of-a-kind observation.
NASA Cassini spacecraft images of Saturn's diaphanous G and E rings are yielding new clues about their structure and formation.
