Remind me again why I love Cassini? Oh yeah, because of images like this. π

Backlit Dione
Here’s a beautiful new image just in from Cassini: the silhouette of 700-mile-wide Dione seen against the sunlit limb of Saturn, its rings seen edge-on just above the moon. Some of Dione’s heavily-cratered terrain can be discerned along its southeastern edge. I particularly like the light halo effects along the edges of the moon and…
The Many Faces of Enceladus
A recently uploaded raw image from Cassini, this is a full-frontal view of 318-mile-wide Enceladus taken on November 30, 2010 during the spacecraft’s most recent flyby. Of particular note here is the moon’s heavily grooved and fractured surface, mostly water ice and rock, but strangely split into two sections of differing terrain β most noticeably…
Enceladus and the Rings
Here’s a surreal image of ice-covered Enceladus with Saturn’s rings in the background, as seen by Cassini on November 30, 2010 during its latest flyby. Amazing! The spacecraft was about 28,500 miles (45,827 km) away from Enceladus when this image was taken. I adjusted the levels a bit to bring out some detail in the…
Spray It, Don’t Say It
Cassini’s done it again…images of Enceladus’ south-pole jets in all their icy glory are in from yesterday’s flyby! The one shown here, a raw image that I’ve rotated 180ΒΊ (so south is “down”) shows the moon lit partly by sunlight (the sliver of white crescent along the left) and partly by “Saturnshine” (reflected sunlight off…
Spongebob Spacepants
Covered with deep, punched-in craters, Saturn’s 168-mile- (270-km-) wide moon Hyperion resembles a sea sponge more than it does a moon. But a moon it is…in fact, Hyperion is the largest irregularly-shaped moon in the solar system. This image, one of the first sent back from Cassini since awakening from its three-week-long “safe mode” following…
From the LITD Archives: Sheer Elegance
Originally posted on March 13, 2009, here’s a quick reprint in honor of Cassini’s return to business! Viewed from the unlit side, the delicate transparency of Saturn’s innermost “C” Ring becomes apparent in this photo. Saturn’sΒ upperΒ atmospheric haze can be seen through the dark material of the rings. This photo shows a natural color view. Image…
Waiting for Cassini
Color portrait of Saturn from Cassini It’s no secret to anyone who’s been following my posts these last couple of years…images from theΒ ο»ΏCassiniο»Ώ mission are my personal favorites and make up more thanΒ half of all my posts. So you can imagine my dismay when Cassini went into a “safe” mode over the past…
Saturn’s “Storm Alley”
Dark swirling vortices march along Saturn’s “storm alley” in this section of an image taken by Cassini on May 19, 2008. (It was recently uploaded as a featured image on JPL’s Flickr page.) Storms on Saturn are huge and powerful, with winds blowing many hundreds of miles per hour and often featuring lightning ten thousand…
From the LITD Archives: Wave Forms
(Originally posted on June 27, 2009)Β Cast shadows reveal some interesting structure in the waves sent up by little Daphnis in this image, taken by the Cassini spacecraft on June 26, 2009. Daphnis orbits Saturn within the 26-mile-wide Keeler gap in the A ring. Its gravity disrupts the edges of the gap, carving scalloped edges in…
Good Vibrations
Dynamic spike-like structures along the edges of Saturn’s rings are caused by oscillations of material that mimics the behavior of our entire galaxy…in other words, Saturn’s rings are a miniature version of the Milky Way! Along the outer edge of the dense B ring Cassini mission scientists have observed ring particles rising above the ringplane…
Peak Time
A crater’s central peak casts a long shadow in this image from Cassini, taken on October 17 as the spacecraft passed by Dione at a distance of 25,000 miles. 700-mile-wide Dione is literally covered in craters, faults and gouges, a testament to the ancient age of its frozen terrain. Many larger craters β like the…
