NASA’s Cassini Spacecraft captures images of lightning on the day side of Saturn

The arrow on the left points to a bluish flash of daytime lightning on Saturn. The image is from the Cassini spacecraft, which tracked a great storm that raged on Saturn through much of 2011. The lightning flashes appear brightest in the blue filter of Cassini’s imaging camera on March 6, 2011. Scientists aggressively heightened the blue tint of the image to determine its size and location.
