Venus
High Pass Filtered Color Image From 2.7 Million Km

Galileo image of Venus taken from 2.7 million km. In order to emphasize cloud features a high-pass spatial filter was applied and the image was colorized blue. The original image was taken through the violet filter. The sub solar point, indicating local noon, is the bright spot at right, and the evening terminator is at left. The clouds are moving to the west (left) at about 100 m/s (230 miles/hr) at the equator. Also visible are the polar hoods at top and bottom. Venus is 12,100 km in diameter and north is up. (Galileo, P-37222)
