Description

Quite pronounced cloud patterns in the Uv , and even patterns in RGB (very unusual for me).  

The atmosphere of Venus turns slowly so the sunward side gets strongly heated, creating the huge convection currents seen here, bringing an unknown, UV-absorbing chemical to the upper cloud layers. Towards the poles, the clouds cool and lose their capacity to absorb UV, creating the bright collars around the poles.
