“This is a view of a ~2,000-km-wide vortex of swirling clouds above Saturn's north pole, imaged in polarized light with Cassini's narrow-angle camera on November 27, 2012. I've processed the original monochrome image to approximate the color of the area at the time.” — Jason Major
Dust Storm On Mars
A dust storm in Olympia Planum's north polar dune fields was triggered by a late Martian summer cold front. As the northern polar cap shrinks fast, it releases cold air that sometimes moves south, like on Earth. These cold fronts strengthen in late summer and early fall due to temperature differences. Occasionally, they cause big dust storms covering large areas or the whole planet. A similar event happened a month later, leading to a global dust storm lasting most of 2018. The image, taken on April 3, 2018, by the Mars Express HRSC camera during orbit, shows natural colors. [ see full image by Aster Cowart ]
