This is a close-up image of Senkyo, a large region on Titan made up of dark dune fields. Regions like this are called “low albedo” , or low reflectivity, areas and they wrap around the moon’s equatorial region. The dunes may be made up of material that falls from Titan’s thick smoglike atmosphere. When weather…

In the Stream of Stars
Titan floats in front of a streaked backdrop of stars in this photo from Cassini, taken on November 30. The Cassini orbiter was nearly a million and a half miles away from Titan when it took this image. Typically images aren’t exposed to capture both moons and stars…when they are, the results can be fascinating….
Eye on Iapetus
Saturn’s moon Iapetus shows its bright (and lumpy!) side in this image from Cassini, taken on November 29. Like many people I know, 914-mile-wide Iapetus has a dark side and a bright side, its bright surface composed of water ice and rock and its dark half a coating of material, most likely from the newly-discovered…
Rising from the Haze
No, it’s not the Enterprise emerging from Titan’s clouds, it’s Tethys, seen in the distance through the larger moon’s outer layer of hydrocarbon haze. Tethys’ giant Odysseus crater is easily visible adorning its north pole and slicing into its terminator. This image was taken on November 26, 2009 by the Cassini spacecraft at a…
Northern Exposure
This video shows the movement of energetic aurora over Saturn’s northern hemisphere, taken by the Cassini spacecraft over the course of four days. Saturn’s aurora is caused by the same process as found on Earth but the results are much, much larger…some of the lights seen here stretch nearly 750 miles above the edge of…
Ennie and the Jets
Another great image from the latest flyby of Enceladus by the Cassini spacecraft, this one shows three frigid plumes firing off into space from the moon’s south pole. More images from the flyby can be seen on my previous posts, or by going to the CICLOPS site listed in the sidebar. This last flyby…
Cold and Bright
After making its flyby early Saturday morning the Cassini spacecraft captured this full-sized view of Enceladus from a distance of about 83,000 miles. (Image has been level-adjusted to bring out surface details. Original raw image can be seen here.) 318 miles across at its widest point, Enceladus’ wrinkled surface is composed of water ice that…
Images from Enceladus!
The raw images from Cassini’s eighth flyby of Enceladus are in! And they don’t disappoint…the highlight of the set so far, in my opinion, is the image above showing the moon’s signature ice geysers erupting from fracture lines called “tiger stripes” surrounding the south pole. Highlighted by sunlight, the plumes follow the lines of the…
Enceladus and Rhea
In another stately pas de deux as seen from the point of view of the Cassini spacecraft, moons Rhea and Enceladus slip past each other in their eternal travels around Saturn. This animation is made up of 20 raw images from Cassini, taken on November 15, level-adjusted and rotated 90º clockwise. Enceladus is about to…
An Example of Extremes
Giant, haze-covered Titan sits in front of  craggy, potato-shaped Hyperion in this image from Cassini, taken on November 13. These two vastly different moons occupy neighboring orbits and thus affect each other’s travels around Saturn…although Titan obviously takes the lead in this dance. 168-mile-wide Hyperion is forced to speed up and slow down as it…
Saturn’s Darker Side
Released November 9, 2009, this image from Cassini shows the northern night side of Saturn sending a deep shadow across its rings while the 700-mile-wide Dione looks on. The shepherd moon Pandora can be seen here as well, orbiting just outside the thin F ring, at center. The Cassini spacecraft was over 800,000 miles from…
Composition in White
949-mile-wide Rhea floats in front of the rings and the brightly-lit face of Saturn in this image from Cassini, taken on November 8. The face of Saturn, overexposed here in order to see detail in the rings and Rhea, appears as bright white, making a dramatic studio backdrop. The planet’s uppermost atmospheric haze is also…
