Saturn

These two side-by-side views show the longest-lived electrical storm yet observed on Saturn by NASA's Cassini spacecraft, in these images released by NASA April 29, 2008. The views were acquired more than three months after the storm was first detected from its lightning-produced radio discharges on Nov. 27, 2007. The view at left was created by combining images taken using red, green and blue spectral filters, and shows Saturn in colors that approximate what the human eye would see. The storm stands out with greater clarity in the sharpened, enhanced color view at right. REUTERS/NASA/JPL/Space Science Institute/Handout (UNITED STATES). FOR EDITORIAL USE ONLY.
