Venus from Galileo

Caption NASA originale:"This colorized picture of Venus was taken February 14, 1990, from a distance of almost 1,7 MMs, about 6 days after Galileo'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 planet's atmosphere are most prominent in violet and ultraviolet light".
