This image of turbulent clouds on Saturn was taken by the Cassini spacecraft narrow-angle camera on August 13, 2007 using a spectral filter sensitive to wavelengths of infrared light centred at 750 nanometers, when the spacecraft was approximately 4.1 million kilometres from Saturn.
The image is centred on a region 24 degrees north of Saturn's equator. Shadows cast by the rings cover the bottom of the image.

This image of Saturns atmosphere was taken with the Cassini spacecraft wide-angle camera on July 28, 2007 using a spectral filter sensitive to wavelengths of infrared light centred at 889 nanometers, when the spacecraft was approximately 3.1 million kilometres away. The view looks toward an area about 9 degrees south of the planet's equator.

This image shows bright, circular cloud features in the turbid atmosphere of Saturn.
The image was taken by the Cassini spaceprobe Cassini spacecraft narrow-angle camera using a spectral filter sensitive to wavelengths of infrared light centred at 750 nanometres. The view was obtained on July 8, 2007 when the spacecraft was approximately 2.9 million kilometres from Saturn.

Saturn's jet stream winds
Permalink  
 


New Cassini research suggests eddies, or giant rotating storms, are the "engine" powering Saturn's jet stream winds.

"The new information about how Saturn's jet streams are powered is exactly the opposite of what we thought prior to Cassini" - Anthony Del Genio of NASA's Goddard Institute for Space Studies, New York, N.Y.

Del Genio is a Cassini imaging team member and lead author of a paper describing this research in press in the journal Icarus.
Jet streams are motions in an atmosphere that carry clouds rapidly eastward or westward. The eddies get fed into the jet streams, in much the same way that rotating gears can power a conveyor belt.

"While we thought the conveyor belt--in this case, the jet streams--powered the rotating eddies, we now think the opposite: the rotating eddies power the jet streams" - Anthony Del Genio.

Images taken using red, green and blue spectral filters were combined to create this colour view.
The image was taken with the Cassini spacecraft narrow-angle camera on April 1, 2007 at a distance of approximately 2 million kilometres from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 86 degrees. Image scale is about 12 kilometres per pixel.
