Das Universum malt einen psychedelischen Traum.

|
> The spinning vortex of Saturn's north polar storm resembles a deep red
|
|
> rose of giant proportions surrounded by green foliage in this
|
|
> false-color image from NASA's Cassini spacecraft. Measurements have
|
|
> sized the eye at a staggering 1,250 miles (2,000 kilometers) across
|
|
> with cloud speeds as fast as 330 miles per hour (150 meters per
|
|
> second).

|
|
> This image is among the first sunlit views of Saturn's north pole
|
|
> captured by Cassini's imaging cameras. When the spacecraft arrived in
|
|
> the Saturnian system in 2004, it was northern winter and the north
|
|
> pole was in darkness. Saturn's north pole was last imaged under
|
|
> sunlight by NASA's Voyager 2 in 1981; however, the observation
|
|
> geometry did not allow for detailed views of the poles. Consequently,
|
|
> it is not known how long this newly discovered north-polar hurricane
|
|
> has been active.

|
|
> The images were taken with the Cassini spacecraft narrow-angle camera
|
|
> on Nov. 27, 2012, using a combination of spectral filters sensitive to
|
|
> wavelengths of near-infrared light. The images filtered at 890
|
|
> nanometers are projected as blue. The images filtered at 728
|
|
> nanometers are projected as green, and images filtered at 752
|
|
> nanometers are projected as red. In this scheme, red indicates low
|
|
> clouds and green indicates high ones.

|
> The view was acquired at a distance of approximately 261,000 miles
|
|
> (419,000 kilometers) from Saturn and at a sun-Saturn-spacecraft, or
|
|
> phase, angle of 94 degrees. Image scale is 1 mile (2 kilometers) per
|
|

|
|

|
|

|
|
> Directorate, Washington, D.C. The Cassini orbiter and its two onboard
