Cyclone lasting more than 5 years is detected on Saturn

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...

Cassini’s CIRS reveals Saturn is on a cosmic dimmer switch

Like a cosmic light bulb on a dimmer switch, Saturn emitted gradually less energy each year from 2005 to 2009, according to observations by NASA's Cassini spacecraft. But unlike an ordinary bulb, Saturn's southern hemisphere consistently emit...

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. Instead, it should have frozen solid billions of years ago. Located in the frigid outer solar system, it's too far from...

NASA spots monster gas cloud around Jupiter moon

Using a sensitive new imaging instrument on NASA's Cassini spacecraft, researchers have discovered a large and surprisingly dense gas cloud sharing an orbit with Jupiter's icy moon Europa. Stretching millions of miles around Jupiter, the donut-shaped cloud, known as a "torus," is believed to result from the uncommonly severe bombardment of ion radiation that Jupiter sends toward Europa. That radiation damages Europa's surface, kicking up and pulling apart water-ice molecules and dispersing them along Europa's orbit into a neutral-gas torus with a mass of about 60,000 tons.

Cassini Spacecraft Camera Sights Saturn

Thar she blows.The Cassini Imaging Team today is releasing a color composite image of Saturn and its moon, Titan, 20 months before the Cassini spacecraft arrives at the planet. The image is available online from NASA's Jet Propulsion Laboratory at and from the Cassini Imaging Team's University of Arizona site. The image shows the shadow of the planet falling across its famous rings and includes Saturn's largest moon, Titan.
