Cassini Spies Wave Rattling Jet Stream on Jupiter
New movies of Jupiter are the first to catch an invisible wave shaking up one of the giant planet's jet streams, an interaction that also takes place in Earth's atmosphere and influences the weather. View More (2012-03-14)
Oxygen detected in atmosphere of Saturn's Moon Dione
Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. View More (2012-03-05)
Enceladus rains water onto Saturn
ESA's Herschel space observatory has shown that water expelled from the moon Enceladus forms a giant torus of water vapour around Saturn. The discovery solves a 14-year mystery by identifying the source of the water in Saturn's upper atmosphere. View More (2011-07-27)
Cassini and telescope see violent Saturn storm
NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope tracked the growth of a giant early-spring storm in Saturn's northern hemisphere that is so powerful it stretches around the entire planet. View More (2011-05-20)
Beams of electrons link Saturn with its moon Enceladus
Data from NASA's Cassini spacecraft have revealed that Enceladus, one of Saturn's diminutive moons, is linked to Saturn by powerful electrical currents - beams of electrons that flow back and forth between the planet and moon. View More (2011-04-21)
Cassini spacecraft observes seasonal rains on Titan
As spring continues to unfold on Saturn, April showers on the planet's largest moon, Titan, have brought methane rain to its equatorial deserts, as revealed in images captured by NASA's Cassini spacecraft. View More (2011-03-18)
2-timing spacecraft has date with another comet
NASA's Stardust spacecraft, equipped with the University of Chicago's Dust Flux Monitor Instrument (DFMI), is hurtling at more than 24,000 miles an hour toward a Valentine's Day encounter with comet Tempel 1. View More (2011-02-14)
Surprise Hidden in Titan's Smog: Cirrus-Like Clouds
Every day is a bad-air day on Saturn's largest moon, Titan. Blanketed by haze far worse than any smog belched out in Los Angeles, Beijing or even Sherlock Holmes's London, the moon looks like a dirty orange ball. View More (2011-02-04)
Demise of large satellite may have led to the formation of Saturn's rings and inner moons
Simulations performed at Southwest Research Institute may explain how Saturn's majestic rings and icy inner moons formed following the collision of a Titan-sized satellite with the planet, according to a paper published in Nature magazine's Dec. 12 Advance Online Publication. View More (2010-12-13)
Cassini reveals oxygen atmosphere of Saturn's moon Rhea
A tenuous atmosphere infused with oxygen and carbon-dioxide has been discovered at Saturn's moon Rhea by the Cassini-Huygens mission, the first time a spacecraft has captured direct evidence of an oxygen atmosphere at a world other than Earth. View More (2010-11-29)
Titan's haze may hold ingredients for life
In an experiment exploring the chemical processes that might be going on in the hazy atmosphere enshrouding Saturn's largest moon, a University of Arizona-led team of scientists discovered a variety of complex organic molecules - including amino acids and nucleotide bases, the most important ingredients of life on Earth.

Saturn's Icy Moon May Keep Oceans Liquid with Wobble
Saturn's icy moon Enceladus should not be one of the most promising places in our solar system to look for extraterrestrial life. View More (2010-10-08)
Avoid Swimming in Interplanetary Lakes
Titan, one of Saturn's moons, is the only moon in the solar system with an atmosphere - ten times denser than the atmosphere of Earth. View More (2010-09-22)
Discovery of Saturn's auroral heartbeat
An international team of scientists led by Dr Jonathan Nichols of the University of Leicester has discovered that Saturn's aurora, an ethereal ultraviolet glow which illuminates Saturn's upper atmosphere near the poles, pulses roughly once per Saturnian day. View More (2010-08-04)
Caltech scientists measure changing lake depths on Titan
On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake-level changes on Saturn's largest moon, Titan-the only other place in the solar system seen to have a hydrological cycle with standing liquid on the surface.

Man-made aurora to help predict space weather
For more than 25 years, our understanding of terrestrial space weather has been partly based on incorrect assumptions about how nitrogen, the most abundant gas in our atmosphere, reacts when it collides with electrons produced by energetic ultraviolet sunlight and "solar wind."

Cassini shows Saturnian roller derby
The seemingly serene orb of Saturn is in fact a gas giant with extraordinary patterns of charged particles and rough and tumble roller derbies for rings. View More (2010-03-19)
Saturn's aurorae images 'unique to science'
Scientists from the University of Leicester have led an international study to capture space images that are unique to science. View More (2010-02-12)
Caltech scientists discover fog on Titan
Saturn's largest moon, Titan, looks to be the only place in the solar system-aside from our home planet, Earth-with copious quantities of liquid (largely, liquid methane and ethane) sitting on its surface. View More (2009-12-18)
