Ultraviolet image of Venus' clouds as seen by the en:Pioneer Venus Orbiter (en:February 26, en:1979). The immense C- or Y-shaped features which are visible only in these wavelengths are individually short lived, but reform often enough to be considered a permanent feature of Venus' clouds. The mechanism by which Venus' clouds absorb ultraviolet is not well understood.
