NASA : Europa's Stunning Surface .- Superficie impresionante de satélite Europa de Júpiter

Hola amigos : A VUELO DE UN QUINDE EL BLOG., hemos recibido la información de la Agencia Espacial NASA, sobre una impresionante vista del satélite Europa que circula alrededor de Júpiter, la vista fue captada por la nave Galileo de la NASA.
NASA nos dice ..."La superficie enigmática y fascinante de helada luna de Júpiter, Europa ocupa un lugar preponderante en esta imagen en color recién reprocesado-, a partir de imágenes tomadas por la nave espacial Galileo de la NASA a finales de 1990. Esta es la opinión de color de Europa desde Galileo Que muestra la mayor parte de la superficie de la luna en la resolución más alta.......La vista fue ilustrado lanzado previamente como un mosaico con menor resolución y color fuertemente reforzada (véase PIA02590). Para crear esta nueva versión, las imágenes fueron montadas en una visión realista del color de la cola superficie aproxima cómo Europa aparecería al ojo humano........La escena muestra la asombrosa diversidad de la geología de la superficie de Europa. , Grietas y crestas lineales largos atraviesan la superficie, interrumpidas por regiones de terreno perturbado donde la corteza de hielo superficial se ha roto y volver a congelar en nuevos patrones......."

Europa's Stunning Surface
The puzzling, fascinating surface of Jupiter’s icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA's Galileo spacecraft in the late 1990s. This is the color view of Europa from Galileo that shows the largest portion of the moon's surface at the highest resolution.
The view was previously released as a mosaic with lower resolution and strongly enhanced color (see PIA02590). To create this new version, the images were assembled into a realistic color view of the surface that approximates how Europa would appear to the human eye.
The scene shows the stunning diversity of Europa’s surface geology. Long, linear cracks and ridges crisscross the surface, interrupted by regions of disrupted terrain where the surface ice crust has been broken up and re-frozen into new patterns.
Color variations across the surface are associated with differences in geologic feature type and location. For example, areas that appear blue or white contain relatively pure water ice, while reddish and brownish areas include non-ice components in higher concentrations. The polar regions, visible at the left and right of this view, are noticeably bluer than the more equatorial latitudes, which look more white. This color variation is thought to be due to differences in ice grain size in the two locations. 
Images taken through near-infrared, green and violet filters have been combined to produce this view. The images have been corrected for light scattered outside of the image, to provide a color correction that is calibrated by wavelength. Gaps in the images have been filled with simulated color based on the color of nearby surface areas with similar terrain types.
This global color view consists of images acquired by the Galileo Solid-State Imaging (SSI) experiment on the spacecraft's first and fourteenth orbits through the Jupiter system, in 1995 and 1998, respectively. Image scale is 1 mile (1.6 kilometers) per pixel. North on Europa is at right.
The Galileo mission was managed by NASA's Jet Propulsion Laboratory in Pasadena, California, for the agency's Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology, Pasadena.
