Among the interplay of Saturn's shadow and rings, Mimas, which appears in the lower-right corner of the image, orbits Saturn as a set of the ever-intriguing spokes appear in the B ring (to the right of center) in this image from NASA's Cassini spacecraft.
Winter is approaching in the southern hemisphere of Saturn and with this cold season has come the familiar blue hue that was present in the northern winter hemisphere at the start of NASA's Cassini mission.
On July 19, 2013, in an event celebrated the world over, NASA's Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings, and, in the background, our home planet, Earth.
The area within Saturn's north polar hexagon is shown by NASA's Cassini spacecraft to contain myriad storms of various sizes, not the least of which is the remarkable and imposing vortex situated over the planet's north pole.
The shadows of Saturn's rings edge ever farther southward as Saturn creeps towards southern winter (or northern summer). Saturn is now almost exactly halfway between its equinox (August 2009) and southern winter solstice (in May 2017).
NASA's Cassini spacecraft takes full advantage of the sunlight to capture these amazing views of the north polar hexagon and myriad storms, large and small, that comprise the weather systems in the polar region.
NASA's Cassini spacecraft shows Saturn's shadow cutting sharply across its rings as the orbits of ring particles carry them suddenly from day to night. With no atmosphere to scatter light, shadows in space are much darker than we're used to here on Earth.
Ghostly spokes in Saturn's B ring continue to put on a show for NASA's Cassini spacecraft cameras in this recent image. The spokes, believed to be a seasonal phenomenon, are expected to disappear as Saturn nears its northern hemisphere summer.
Dawn on Saturn is greeted across the vastness of interplanetary space by the morning star, Venus, in this image from NASA's Cassini spacecraft. Venus appears just off the edge of the planet directly above the white streak of Saturn's G ring.
Saturn's north polar hexagon basks in the Sun's light now that spring has come to the northern hemisphere. Many smaller storms dot the north polar region and Saturn's signature rings put in an appearance in the background.
NASA's Cassini spacecraft simultaneously peers through the haze in Titan's equatorial region down to its surface and captures the vortex of clouds hovering over its south pole just to the right of the terminator on the moon's dark side.
