Cassini views of Europa, Ganymede and Callisto

Cassini views of Europa, Ganymede and Callisto
Cassini views of Europa, Ganymede and Callisto These color views of Europa, Ganymede and Callisto, taken by the Cassini Imaging Science Subsystem (ISS), were created using 3 polarized UV and GRN filtered images and stacking them together to reduce noise. Various IR images were also stacked except in the case of Europa, where only a single red frame from the ISS existed and, consequently, the red channel is very noisy. The images have been magnified by a factor of 3. NASA / JPL-Caltech / SSI
