This colorized picture of Venus was taken on February 14, 1990, from a distance of 1.7 million miles, 6 days after the Galileo spacecraft's closest approach to the planet. It has been colorized to a bluish hue to emphasize subtle contrasts in the cloud markings and to indicate that it was taken through a violet filter. Features in the sulfuric acid clouds near the top of the plantet's atmosphere are most prominent in violet and ultraviolet light. (NASA photo caption)
