Another awesome upload by Gordan Ugarkovic, here’s a color-composite image from Cassini data taken in December 2009 showing a jetting Enceladus lit by “Saturnshine” – reflected diffused sunlight from an off-frame Saturn – and given a Saturn-y coloration at the same time! Icy Enceladus is typically a bright white color, with some grey and…

Ring King
The bright band in this image is a cross-section of a massive new ring discovered around Saturn, a cold, diffuse and incredibly thick band of material orbiting the planet 3.7 million miles out…..much farther out than any of the other rings and farther away even than most of Saturn’s moons. The ring is so…
The Ghost and the Darkness
A spectral figure casts a long shadow as it travels along the path of Saturn’s F ring on August 7, 2009 in this image from the Cassini orbiter. Not a ghost per se but rather a clump of ring material, pulled upwards from the rest of the ring plane by what is perhaps a small…
The Ring
No, it’s not the final frame of a haunted videotape…it’s a backlit Titan, silhouetted against the sun, photographed by Cassini from over 850,000 miles away. Titan’s upper-level atmospheric haze is illuminated in this image, surrounding the moon high above the cloudtops. The haze is a mixture of complex hydrocarbons created by the breakdown of methane…
Subtle Shades
The intricate structure of Saturn’s rings is seen here in this raw image from Cassini, taken yesterday. This (I believe) shows the dark material of the Cassini Division (bottom) below the brighter bands of the A ring (middle to top). I could be mistaken though, and this is instead the inner section of the B…
Wave Rider
4.3-mile-wide Daphnis races along its track, the 26-mile-wide Keeler Gap in Saturn’s A ring, stirring up sinuous edge waves in the ring material behind and before it. Not only does the shepherd moon cast a small shadow onto the ring, but so do the crests of the waves it’s creating! It’s a wonderful little…

Another animation, this time from April 24, 2009, made from 116 raw images from the Cassini spacecraft. The orbiting Cassini focused its camera on Prometheus as it dipped into the F ring and back out again, pulling the icy dust into wispy strands with its passing. Prometheus’ oblong shape can be seen clearly here…it…

This 14-frame animation shows the effect of Prometheus on Saturn’s F ring as it travels alongside, its gravity pulling the ring material into streamers that trail in its wake. A clump of ring material leads in front of the moon on the opposite side of the ring. Honestly, I’m not sure what causes this…
The Pull of Prometheus
Prometheus’ effect on Saturn’s ropy F ring is evident in this photo from Cassini, taken March 7, 2009. As the irregularly-shaped shepherd moon approaches the ring material in its looping orbit around Saturn, it draws material from the ring in towards itself, warping and stretching the ring particles into waving streamers that eventually settle and…
