This close-up of Saturn's atmosphere shows turbulent activity on the
ragged edge of the equatorial cloud band. The turbulence is a direct
result of internal heat from the planet and absorbed sunlight, and is
generally lower in Saturn's bland atmosphere than in the atmospheres of
Jupiter and Earth. The lower level of turbulence on Saturn may account
for its higher wind speeds, compared to Jupiter and Earth.
The image was taken with the Cassini spacecraft narrow angle camera on
Sept. 25, 2004, at a distance of 7.7 million kilometers (4.8 million
miles) from Saturn through a filter sensitive to wavelengths of infrared
light centered at 889 nanometers. The image scale is 92 kilometers (57
miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the
European Space Agency and the Italian Space Agency. The Jet Propulsion
Laboratory, a division of the California Institute of Technology in
Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission
Directorate, Washington, D.C. The Cassini orbiter and its two onboard
cameras were designed, developed and assembled at JPL. The imaging team
is based at the Space Science Institute, Boulder, Colo.
