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…
Big Sisters
Rhea and Titan, Saturn’s two largest moons, align in Cassini’s lens in this image taken on November 19, 2009. I level-adjusted and rotated the original raw image file…”north” would be to the right in this view. Rhea is 949 miles wide, cold, icy and airless. Titan, 3,200 miles wide, is also frigidly cold but is…
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…
Now that’s a big shadow!
This was a suprising find amongst the raw images from Cassini this evening….a photo of Saturn, similar to the one I posted previously, but with a massive shadow cast upon its southern hemisphere. I presume it’s from Titan, somewhere out of frame, based upon its size and hazy edges (indicative of the big moon’s thick…
Along the Edge
Moons Rhea and Enceladus orbit along the ringplane in this view from Cassini, taken November 6, 2009. That is, I think it’s Rhea and Enceladus in this image. It’s hard to tell for sure from this distance. (Cassini was over 1.2 million miles from Saturn when this was shot.) If anyone knows for sure, I’m…
No Editing Required
This raw image from Cassini requires no editing to be presentable…..it’s simply a beautiful shot of Mimas hovering in front of the rings with Saturn’s shadow cast across them. Simple, untouched beauty at its best. That little Cassini….he’s getting good at this. 🙂 Image: NASA/JPL/Space Science Institute
