Hexágono en Saturno

Ayer leí esta nota que capturó mi atención de inmediato:

"A bizarre six-sided feature encircling the north pole of Saturn is pictured by the visual and infrared mapping spectrometer on NASA's Cassini spacecraft, in this image released by NASA March 27, 2007. This image is one of the first clear images ever taken of the north polar region as seen from a unique polar perspective and was originally discovered and last observed by a spacecraft during NASA's Voyager flybys of the early 1980's. The new views of the polar hexagon taken in late 2006 prove that this is an unusually long-lived feature on Saturn. This image is the first to capture the entire feature and was taken October 29, 2006. REUTERS/NASA/JPL/University of Arizona/Handout. "

La imágen es tal y como se ve aquí. Para ver un video de como está rotando este hexágono en el Polo Norte de Saturno, vayan a la siguiente página de la NASA:

Aparte de estas, hay un buen número de imágenes tomadas por Cassini, así como de notas relacionadas a los estudios de esta misión.
