Wavy Polar Jet

Oct 06, 2014
Although it looks like a simple hexagon, this feature surrounding Saturn's north pole is really a manifestation of a meandering polar jet stream. This image was taken by NASA's Cassini spacecraft.

Nature is often more complex and wonderful than it first appears. For example, although it looks like a simple hexagon, this feature surrounding Saturn's north pole is really a manifestation of a meandering polar jet stream. Scientists are still working to understand more about its origin and behavior.

For more on the hexagon, see PIA11682.

This view looks toward the sunlit side of the rings from about 33 degrees above the ringplane. The image was taken in red light with the Cassini spacecraft wide-angle camera on July 24, 2013.

The view was acquired at a distance of approximately 605,000 miles (973,000 kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 19 degrees. Image scale is 36 miles (58 kilometers) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
