Veiled Venus

Veiled Venus

. Bright opaque clouds of sulfuric acid wrap around Venus. The creamy yellow veil of clouds circulates once around the planet in only four Earth days, moving at speeds of up to 100 meters per second. Strong zonal winds combine with weaker poleward winds to carry the clouds in a slow spiral toward the poles. The thick cloudy atmosphere of Venus always blocks our view of the surface, and warms that surface to a torrid 730 degrees kelvin. (Courtesy of NASA.)
