APOD: Saturn Hurricane (2013 May 02) Image Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA http://apod.nasa.gov/apod/ap130502.html Explanation: Acquiring its first sunlit views of far northern Saturn late last year, the Cassini spacecraft's narrow-angle camera recorded this stunning image of the vortex at the ringed planet's north pole. The false color, near-infrared image results in red hues for low clouds and green for high ones, causing the north-polar hurricane to take on the appearance of a rose. Enormous by terrestrial hurricane standards, this storm's eye is about 2,000 kilometers wide, with clouds at the outer edge traveling at over 500 kilometers per hour. The north pole Saturn hurricane swirls inside the large, six-sided weather pattern known as the hexagon. Of course, in 2006 Cassini also imaged the hurricane at Saturn's south pole. http://www.ciclops.org/view_event/191/ http://www.jpl.nasa.gov/news/news.php?release=2013-149 http://solarsystem.nasa.gov/news/display.cfm?News_ID=43464 http://saturn.jpl.nasa.gov/news/newsreleases/newsrelease20130429/ http://www.esa.int/Our_Activities/Space_Science/Cassini_eyes_Saturn_hurricane Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130502 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0502 http://asterisk.apod.com/viewtopic.php?t=31277
