Since the NASA / ESA Cassini-Huygens spacecraft arrived at Saturn in 2004, astronomers and space scientists have been able to study the ringed planet and its moons in great detail. Now, for the first time, a team of planetary scientists have made simultaneous measurements of Saturn´s nightside aurora, magnetic field, and associated charged particles. Together the fields and particle data provide information on the electric currents flowing that produce the emissions. Team leader Dr Emma...

Observations of how Saturn's moon Enceladus interacts with its environment show it leaves a complex pattern of ripples and bubbles in its wake. Sheila Kanani will be presenting the results at the RAS National Astronomy Meeting in Glasgow on Thursday April 15th. Enceladus sits deep within Saturn's magnetosphere, which is filled with electrically charged particles (plasma) originating from both the planet and its moons. The Cassini spacecraft has made nine flybys of the mysterious sixth-largest...

Pasadena, Calif. -- In a David and Goliath story of Saturnian proportions, the little moon Enceladus is weighing down giant Saturn's magnetic field so much that the field is rotating slower than the planet. This phenomenon makes it nearly impossible to measure the length of the Saturn day using techniques that work at the other giant planets. "No one could have predicted that the little moon Enceladus would have such an influence on the radio technique that has been used for years to...

JPL -- Saturn's radio emissions could be mistaken for a Halloween sound track.  That's how two researchers describe their recent findings, published in the July 23 issue of the Geophysical Research Letters. Their paper is based on data from the Cassini spacecraft radio and plasma wave science instrument. The study investigates sounds that are not just eerie, but also descriptive of a phenomenon similar to Earth's northern lights. "All of the structures we observe in Saturn's radio...

Iowa -- As NASA's Cassini spacecraft approached Saturn last July, it found evidence that lightning on Saturn is roughly one million times stronger than lightning on Earth. That's just one of several Cassini findings that University of Iowa Space Physicist Don Gurnett will present in a paper to be published Thursday, Dec. 16 in Science Express, an online version of the journal Science, and in a talk to be delivered Friday, Dec. 17 at a meeting of the American Geophysical Union in San...
