Atomic oxygen could never be confused with expensive perfume. But just as a fragrance lingering in the air of an empty room offers hints about a previous occupant, the cloud of oxygen the Cassini spacecraft encountered as it first approached Saturn turned out to be a calling card from another celestial presence, the tiny moon Enceladus. The oxygen was the first clue that much more is going on beneath Enceladus' icy surface than it first appeared. It took a while for scientists to get the...

NASA Cassini spacecraft images of Saturn's diaphanous G and E rings are yielding new clues about their structure and formation. A sequence of recent Cassini images, which has been made into a brief movie, shows an arc of bright material looping around the inside edge of the G ring, a tenuous 7,000-kilometer-wide (4,400 miles) band of dust-sized icy particles lying beyond the F ring by 27,000 kilometers (16,800 miles). Cassini passed between the F and G rings during its insertion into orbit...

As the Cassini spacecraft reaches the halfway mark in its four-year tour of the Saturn system, discoveries made during the first half of the mission have scientists revved up to find out what's in store for the second act. Cassini has been orbiting Saturn since June 30, 2004, studying the planet, its rings and moons. "The spacecraft has spent a considerable amount of time studying the moon Titan during 15 separate flybys so far. In the second half of its prime mission, ending June 2008,...

Saturn's moon Enceladus - an active, icy world with an unusually warm south pole "“ may have performed an unusual trick for a planetary body. New research shows Enceladus rolled over, literally, explaining why the moon's hottest spot is at the south pole. Enceladus recently grabbed scientists' attention when the Cassini spacecraft observed icy jets and plumes indicating active geysers spewing from the tiny moon's south polar region. "The mystery we set out to explain was how the hot...

By Maggie Fox, Health and Science Correspondent WASHINGTON -- The newly discovered outer ring of Uranus is bright blue, for the same reason the Earth's sky is blue -- it is made up of tiny particles, astronomers said on Thursday. It is "strikingly similar" to Saturn's outer ring, which astronomers last month confirmed was probably generated by one of the planet's moons, Enceladus. Like Saturn's ring, the Uranus ring also has a small moon in it, called Mab. But Mab is too small and too cold to...

LOS ANGELES -- To scientists scanning the cosmos for signs of life, the stunning discovery of what appears to be water on an obscure moon orbiting Saturn couldn't come at a more pivotal time. With a fresh focus on returning astronauts to Earth's own moon, NASA has squashed several missions that over the next decade were to have continued the search for extraterrestrial life. Can images from Enceladus, an icy moon located more than 800 million miles from Earth, supercharge interest and...

By Maggie Fox, Health and Science Correspondent WASHINGTON -- One of Saturn's moons, Enceladus, is spewing out a giant plume of water vapor that is probably feeding one of the planet's rings, scientists said on Thursday. The findings, published in the journal Science, suggest that tiny Enceladus could have a liquid ocean under its icy surface which in theory could sustain primitive life, similar to Jupiter's moon Europa. The plume was spotted by Cassini, a joint U.S.-European spacecraft that...

JPL -- NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus. The rare occurrence of liquid water so near the surface raises many new questions about the mysterious moon. "We realize that this is a radical conclusion -- that we may have evidence for liquid water within a body so small and so cold," said Dr. Carolyn Porco, Cassini imaging team leader at Space Science Institute, Boulder, Colo. "However, if...

WASHINGTON -- One of Saturn's moons is spraying icy particles into space from the area around its south pole, a sure sign of geologic activity, NASA reported on Tuesday. Recent images captured by the Cassini spacecraft reveal what looks at first like the narrow crescent shape of a solar eclipse, with plumes of particles being ejected from the Saturn moon Enceladus. "For planetary explorers like us, there is little that can compare to the sighting of activity on another solar system body,"...

JPL -- Jets of fine, icy particles streaming from Saturn's moon Enceladus were captured in recent images from NASA's Cassini spacecraft. The images provide unambiguous visual evidence the moon is geologically active. "For planetary explorers like us, there is little that can compare to the sighting of activity on another solar system body," said Dr. Carolyn Porco, Cassini imaging team leader at the Space Science Institute in Boulder, Colo. "This has been a heart-stopper, and surely one of...

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...
