Summary

Description
English: This picture of Venus was taken by the Galileo spacecraft’s Solid State Imaging System on February 14, 1990, at a range of almost 1.7 million miles from the planet. A highpass spatial filter has been applied in order to emphasize the smaller scale cloud features, and the rendition has been colorized to a bluish hue in order to emphasize the subtle contrasts in the cloud markings and to indicate that it was taken through a violet filter.

The sulfuric acid clouds indicate considerable convective activity, in the equatorial regions of the planet to the left and downwind of the subsolar point (afternoon on Venus). They are analogous to “fair weather clouds” on Earth.

The filamentary dark features visible in the colorized image are here revealed to be composed of several dark nodules, like beads on a string, each about 60 miles across. The Galileo Project is managed for NASA's Office of Space Science and Applications by the Jet Propulsion Laboratory; its mission is to study Jupiter and its satellites and magnetosphere after multiple gravity assist flybys at Venus and Earth.
Español: Esta imagen de Venus fue captada por el Sistema de Formación de Imágenes de Estado Sólido de la nave espacial Galileo el 14 de febrero de 1990 a una distancia de más de 2,7 millones de kilómetros del planeta. Se ha aplicado un filtro especial para eliminar frecuencias bajas (highpass) y así poder apreciar mejor las características de las nubes a pequeña escala; asimismo, se ha coloreado la imagen con un matiz azulado para enfatizar los sutiles contrastes en las marcas de las nubes e indicar que la fotografía se ha capturado utilizando un filtro violeta.

La presencia de nubes de ácido sulfúrico señala una considerable actividad convectiva, concretamente en las regiones ecuatoriales del planeta hacia la izquierda y a sotavento del punto subsolar (tarde venusina). Equivalen a lo que en la Tierra conoceríamos como «nubes de buen tiempo».

Los rasgos oscuros filamentosos que pueden apreciarse en esta imagen coloreada están compuestos de varios nódulos, semejantes a cuentas enhebradas en un hilo, de unos 97 kilómetros de longitud cada uno. El proyecto Galileo es gestionado por el Laboratorio de Propulsión a Reacción para la Oficina de Ciencia y Aplicaciones Espaciales de la NASA; su misión es estudiar Júpiter y sus satélites y magnetósfera tras diversos vuelos con asistencia gravitatoria sobre Venus y la Tierra.
