31 Oct 2012 Titan Glows in the Dark
A literal shot in the dark by imaging cameras on NASA's Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan's atmosphere, but also -- surprisingly -- from deep in the atmosphere through the moon's haze.
26 Oct 2012 Saturn Storm Cranks the Heat WAY Up
Observations taken in the infrared by Cassini as well as from Earth show that a massive storm on Saturn was not just big and violent, it also formed a vortex (a storm within a storm, if you like) that got hot - well, hot for frigid Saturn, that is. In the heart of the system, the temperature rose by an incredible 80° Celsius - a difference in temperature that's like starting in the depths of winter in Anchorage, Alaska and then going to the height of summer in the Sahara!
25 Oct 2012 Cassini Sees Burp at Saturn After Large Storm
NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet's upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.
17 Oct 2012 Keck Observations Bring Weather of Uranus Into Sharp Focus
In 1986, when Voyager swept past Uranus, the probe's portraits of the planet were "notoriously bland," disappointing scientists, yielding few new details of the planet and its atmosphere, and giving it a reputation as a bore of the solar system.  Now, however, thanks to a new technique applied at the Keck Observatory, Uranus is coming into sharp focus through high-resolution infrared images, revealing in incredible detail the bizarre weather of the seventh planet from the sun.
17 Oct 2012 Jupiter: Turmoil from Below, Battering from Above
As Jupiter gets peppered continually with small space rocks, wide belts of the atmosphere are changing color, hotspots are vanishing and reappearing, and clouds are gathering over one part of Jupiter, while dissipating over another.
18 Jul 2012 Cassini Spots Daytime Lightning on Saturn
Saturn was playing the lightning storm blues. NASA's Cassini spacecraft has captured images of last year's storm on Saturn, the largest storm seen up-close at the planet, with bluish spots in the middle of swirling clouds.
10 Jul 2012 The Titanian Seasons Turn, Turn, Turn
Images from NASA's Cassini spacecraft show a concentration of high-altitude haze and a vortex materializing at the south pole of Saturn's moon Titan, signs that the seasons are turning on Saturn's largest moon.
25 Jun 2012 Cassini Shows Why Jet Streams Cross-Cut Saturn
Scientists used images collected over several years by NASA's Cassini spacecraft to discover that the heat from within the planet powers the jet streams.
