Venus
Color Enhanced Image From 2.7 Million Km

Galileo colorized image of Venus taken from 2.7 million km about 5 days after closest approach on 15 February 1990. The exposure was taken through a violet filter and colored blue to enhance contrast. The westward moving sulfuric acid clouds at the equator and polar hoods are visible. Great detail (resolution of about 70 km) can be seen in the cloud structure, which is moving at speeds up to 100 m/s (230 miles/hr). Venus is 12,100 km in diameter, north is up, and the evening terminator is to the left. The bright spot at right is the sub-solar point (local noon). (Galileo, P-37218)
