The unique six-sided jet stream at Saturn's north pole known as "the hexagon" taken by NASA's Cassini mission is seen in this still handout image from a movie released December 4, 2013. The movie, made from images obtained by Cassini's imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.
