Latest Saturn Stories
PASADENA, Calif., April 20, 2011 /PRNewswire-USNewswire/ -- NASA is releasing the first images and sounds of an electrical connection between Saturn and one of its moons.
New analysis of images taken by ESA's Venus Express orbiter has revealed surprising details about the remarkable, shape-shifting collar of clouds that swirls around the planet's South Pole.
Have the surface and belly of Saturn's smog-shrouded moon, Titan, recently simmered like a chilly, bubbling cauldron with ice volcanoes, or has this distant moon gone cold?
Like forensic scientists examining fingerprints at a cosmic crime scene, scientists working with data from NASA's Cassini, Galileo and New Horizons missions have traced telltale ripples in the rings of Saturn and Jupiter back to collisions with cometary fragments dating back more than 10 years ago.
Like a petulant adolescent, Saturn is sending out mixed signals.
This is the first time scientists have obtained current evidence of rain soaking Titan's surface at low latitudes.
Heat output from the south polar region of Saturn's moon Enceladus is much greater than was previously thought possible.
Every day is a bad-air day on Saturn's largest moon, Titan.
NASA announced Tuesday that the Cassini spacecraft passed by and snapped images of several of Saturnâ€™s moons.
Not only does Enceladus likely have an ocean, that ocean is probably fizzy like a soft drink and could be friendly to microbial life.
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...
