Turbulence in Saturn's Atmosphere

neutron_p writes "Today an image of turbulence in the atmosphere of Saturn has been unveiled. This image was taken with the NASA/ESA/ASI Cassini-Huygens spacecraft camera. This pattern is an example of a 'Kelvin-Helmholtz instability', which occurs when two fluids of different density flow past each other at different speeds. This phenomenon should be common on the gas-giant planets."
