Sažetak
Ovo je retuširana slika, što znači da je digitalno izmjenjena u odnosu na svoju izvornu inačicu. Izmjene: Increased linear pixel dimensions (scaled up) by a factor of 1.6 (to bring out fine detail), sharpening. Izvornik se može vidjeti ovdje: PIA19048 realistic color Europa mosaic (original).jpg. Izmjene je napravio: WolfmanSF.

OpisPIA19048 realistic color Europa mosaic edited.jpg |
English: Uploader's notes: the original NASA TIFF image has been modified by increasing linear pixel dimensions by a factor of 1.6 (to bring out fine detail), sharpening and conversion to JPEG format. Original caption released with image: 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 2 miles (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.
