NASA's Cassini spacecraft will be making its close flyby of the northern hemisphere of Saturn's moon Enceladus today, Monday, Dec. 20. The closest approach will take place at 5:08 PM PST (8:08 EST) on Dec. 20, or 1:08 AM UTC on Dec. 21. The spacecraft will zip by at an altitude of about 48 kilometers (30 miles) above the icy moon's surface. Cassini's fields and particles instruments will get priority during this flyby. They will be trying to characterize the particles that may form a tenuous...

Researchers from the University of the Basque Country (UPV/EHU) have been monitoring a cyclone on Saturn for more than five years. This makes it the longest-lasting cyclone detected to date on any of the giant planets of the Solar System. Images from the Cassini probe were used to carry out this study. "Cyclones "“ where the wind turns in the same direction as the planet "“ do not usually last for a long time, and so we were interested to discover one that had gone on for several...

A new analysis based on data from NASA's Cassini spacecraft finds a causal link between mysterious, periodic signals from Saturn's magnetic field and explosions of hot ionized gas, known as plasma, around the planet. Scientists have found that enormous clouds of plasma periodically bloom around Saturn and move around the planet like an unbalanced load of laundry on spin cycle. The movement of this hot plasma produces a repeating signature "thump" in measurements of Saturn's rotating magnetic...

NASA's Cassini spacecraft has found possible ice volcanoes on Saturn's moon Titan that are similar in shape to those on Earth that spew molten rock. Topography and surface composition data have enabled scientists to make the best case yet in the outer solar system for an Earth-like volcano landform that erupts in ice. The results were presented today at the American Geophysical Union meeting in San Francisco. "When we look at our new 3-D map of Sotra Facula on Titan, we are struck by its...

Scientists have an ingenious explanation for the strange ridge belting Saturn's outermost moon, Iapetus For centuries, people wondered how the leopard got its spots. The consensus is pretty solid that evolution played a major role. But it's only been five years since the arrival of high-resolution Cassini Mission images of Saturn's bizarre moon Iapetus that the international planetary community has pondered the unique walnut shape of the large (735 kilometer radius) body, considered by many...

New research suggests that the origin of Saturn's rings may be a case of cosmic murder. According to a new theory published on Sunday in the journal Nature, the rings are the only evidence left of an unnamed moon of Saturn's that disappeared about 4.5 billion years ago The report said that Saturn robbed its outer layer of ice as the moon made its death spiral, which then formed rings. "Saturn was an accomplice and that produced the rings," study author Robin Canup, an astronomer at the...

NASA's Cassini spacecraft successfully dipped near the surface of Saturn's moon Enceladus on Nov. 30. NASA's Cassini spacecraft successfully dipped near the surface of Saturn's moon Enceladus on Nov. 30. Though Cassini's closest approach took it to within about 48 kilometers (30 miles) of the moon's northern hemisphere, the spacecraft also captured shadowy images of the tortured south polar terrain and the brilliant jets that spray out from it. Many of the raw images feature darkened terrain...

New images and data from NASA's Cassini spacecraft give scientists a unique Saturn-lit view of active fissures through the south polar region of Saturn's moon Enceladus. They reveal a more complicated web of warm fractures than previously thought. The new images are available at: http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov. Scientists working jointly with Cassini's composite infrared spectrometer and its high-resolution imaging camera have constructed the highest-resolution...

A NASA probe has discovered oxygen in the atmosphere of one of Saturn's moons, discovering the element alongside carbon dioxide in the thing exosphere of the icy satellite known as Rhea. According to the UK newspaper The Guardian, instruments onboard the Cassini probe were able to acquire samples of both elements in March, when it passed within 100km of Saturn's second largest moon. The results reveal that there is an extremely thin layer of oxygen and carbon dioxide in Rhea's atmosphere, and...

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...

Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...

Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
