Saturn's south pole
Details observed by the NASA/ESA/ASI Cassini-Huygens spacecraft in Saturn's south polar region demonstrate that this area is far from featureless.
Lighter coloured clouds dot the entire region, which is dominated by a central, sharply-defined circular feature. Movie sequences in which these features are captured and followed will allow wind speeds in the polar region to be measured.
This image was taken by the Cassini-Huygens narrow-angle camera on 20 May 2004, from a distance of 22 million kilometres from Saturn.
The Cassini-Huygens mission is a co-operative project of NASA, ESA and ASI, the Italian space agency.
