Venus
Venus photographed in ultraviolet light by the Pioneer Venus Orbiter (Pioneer 12) spacecraft, February 26, 1979. Although Venus's cloud cover is nearly featureless in visible light, ultraviolet imaging reveals distinctive structure and pattern, including global-scale V-shaped bands that open toward the west (left). Added color in the image emulates Venus's yellow-white appearance to the eye.
The atmospheric pressure on Venus is significantly higher than that of Earth. At the elevation of Venus’s mean radius, the surface pressure is approximately 95 bars, or 95 times the atmospheric pressure found at Earth’s surface.1
In terms of millibars, the surface pressure on Venus is about 95,000 millibars, whereas Earth’s sea-level pressure is approximately 1,000 millibars. To put this immense pressure into perspective, the conditions on the surface of Venus are comparable to the pressure found at a depth of about 1 km (0.6 mile) within Earth’s oceans.21
