A team of planetary scientists working on the NASA/ESA/ASI Cassini-Huygens mission has discovered tiny, charged icy particles in the plume from Saturn's moon Enceladus that offer a tantalizing glimpse of the interior of this enigmatic world. Dr Geraint Jones and Dr Chris Arridge, both from University College London's Mullard Space Science Laboratory, will present the results on behalf of the Cassini Plasma Spectrometer (CAPS) instrument team on Wednesday 22nd April at the European Week of...

On February 24, 2009, the NASA/ESA Hubble Space Telescope captured a photo sequence of four moons of Saturn passing in front of their parent planet. The moons, from far left to right, are the white icy moons Enceladus and Dione, the large orange moon Titan, and icy Mimas. Due to the angle of the Sun, they are each preceded by their own shadow. These rare moon transits only happen when the tilt of Saturn's ring plane is nearly "edge on" as seen from the Earth. Saturn's rings will be...

Something is about to happen on Saturn that's so pretty, even Hubble will pause to take a look. "On Feb. 24th, there's going to be a quadruple transit of Saturn's moons," says Keith Noll of the Hubble Space Telescope Science Institute. "Titan, Mimas, Dione and Enceladus will pass directly in front of Saturn and we'll see their silhouettes crossing Saturn's cloudtops"”all four at the same time." Hubble won't be the only one looking. Amateur astronomers will be able to see it, too. The...

The presence of water has long been seen as a key condition for life in planetary environments. Prompted by recent discovery by the NASA's Cassini spacecraft of a water vapor "plume" emanating from Enceladus, one of the Saturnian satellites, radio astronomers wondered how abundant water is in the system of Saturn. The so-called maser emission of water molecules offers the most sensitive and robust way of detecting water vapor at radio wavelengths. This emission is unmistakably recognizable...

U.S. and European space officials are considering proposals to send probes to the outer planets of the solar system. One ambitious plan would send an orbiter to Saturn which would release a lander to the moon Titan. Another plan hopes to see two orbiters sent to Jupiter and to its moons, Europa and Ganymede. In February, Ed Weiler of NASA, and David Southwood of the ESA, will announce which plan will go forward to be discussed more thoroughly. The mission could cost billions of dollars to...

The U.S. space agency says its Cassini spacecraft has detected Saturn's small moon Enceladus is showing signs of ongoing changes at its south polar surface. The National Aeronautics and Space Administration said close views of the southern polar region -- where jets of water vapor and icy particles spew from vents within the moon's distinctive tiger stripe fractures -- provide surprising evidence of Earth-like tectonics. They yield new insight into what may be happening within the fractures,...

SAN FRANCISCO, Dec. 15 /PRNewswire-USNewswire/ -- The closer scientists look at Saturn's small moon Enceladus, the more they find evidence of an active world. The most recent flybys of Enceladus made by NASA's Cassini spacecraft have provided new signs of ongoing changes on and around the moon. The latest high-resolution images of Enceladus show signs that the south polar surface changes over time.

A team of astronomers said on Thursday that supersonic plumes of gas and dust shooting off one of Saturn's moons suggest strong evidence of liquid water, a key building block of life. The new discovery adds to the growing push to further explore the moon Enceladus, as some believe it is one of the solar system's most compelling places for potential life. NASA astronomers estimated through images from the Cassini probe that the mysterious plumes shooting from Enceladus' icy terrain contained...

As major league baseball readies for the World Series, NASA's Cassini team will come to bat twice this month when the spacecraft flies by Saturn's geyser moon, Enceladus. The Oct. 9 flyby is an inside pitch -- the closest flyby yet of any moon of Saturn, at only 25 kilometers (16 miles) from the surface. The Oct. 31 flyby is farther out, at 196 kilometers (122 miles). Scientists are intrigued by the possibility that liquid water, perhaps even an ocean, may exist beneath the surface 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...
