This image from NASA's Cassini spacecraft reveals the wind patterns within a large vortex that was spawned by a giant northern storm on Saturn. The arrows indicate the local direction of the winds. These data were obtained on Jan. 11, 2011. Image released Jan. 31, 2013.
The head of Saturn's huge northern storm is well established in this view captured early in the storm's development by NASA's Cassini spacecraft in late 2010.
Saturn's atmosphere and its rings are shown here in a false color composite made from three images taken in near infrared light through filters that are sensitive to varying degrees of methane absorption. Red and orange colors in this view indicate clouds that are deep in the atmosphere. Yellow and green colors, most noticeable near the top of the view, indicate intermediate clouds. White and blue indicate high clouds and haze. The rings appear as a thin horizontal line of bright blue because they are outside of the atmosphere and not affected by methane absorption.
This view looks toward the southern, unilluminated side of the rings from just below the ringplane

Magnifique Saturne et ses quelques lunes …
Ce point de vue en gros plan du disque de Saturne révèle le transit de plusieurs lunes qui passent devant la planète géante gazeuse.
La lune géante et orange Titan - plus grande que la planète Mercure - peut être vue en haut à droite.
Les lunes glacées blanches qui sont beaucoup plus près de Saturne, donc beaucoup plus proches du plan de l'anneau dans cette vue, sont, de gauche à droite: Encelade, Dioné et Mimas.
La bande sombre qui traverse la face de la planète légèrement au-dessus des anneaux est l'ombre des anneaux qui se projette sur la planète. Cette image a été prise avec grand champ de Hubble de Planetary Camera 2 le 24 Février 2009, lorsque Saturne était à une distance d'environ 1,25 milliards kilomètres de la Terre. Hubble peut voir les détails aussi petits que 300 kilomètres sur Saturne.
