Hey everyone! Today, THIS is happening: That’s right — the entire planet will be photographed from Saturn by Cassini, 900 million miles away. So whatever you’re doing at that particular time, take a moment to look up, smile and wave! This will be one for the history books. Read more here.

Ring Shadows Surround Saturn’s South
Cassini gets a great look at Saturn’s southern half in this color-composite, assembled from raw images acquired on July 13, 2013. Click for a larger view in my Flickr stream (the original raw images were only 1024 px, so it’s still a little grainy.) I adjusted the channel histograms quite a bit to achieve a…
On July 19, Smile and Wave at Saturn
…because Cassini will be watching — and taking pictures! In three weeks, on Friday, July 19, the Cassini spacecraft will be taking pictures from orbit around Saturn, capturing the ringed planet in eclipse against the Sun. This will not only provide fantastic views of the planet’s rings and atmosphere, but will also include another treat:…
Dione to Join the List of Moons with Underground Oceans?
Earth may display its seas on its surface for all the Universe to see, but further out in the Solar System liquid oceans are kept discreetly under wraps, hidden beneath cratered surfaces of ice and rock. And while Saturn’s moon Enceladus sprays its salty subsurface ocean out into space, other moons are less ostentatious —…
Look Into the Blood-Red Eye of Saturn’s Polar Hurricane
An incredible 1,200-mile-wide vortex of spiraling clouds swirling above Saturn’s north pole is seen in all its glory in this stunning image from NASA’s Cassini spacecraft, originally captured last year but recently released by NASA on April 29. Taking advantage of a new orbital trajectory that puts it high above Saturn’s rings and poles, Cassini…
Proof that Meteors Hit Saturn’s Rings… a Lot
(News from NASA) NASA’s Cassini spacecraft has provided the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn’s rings. These observations make Saturn’s rings the only location besides Earth, the Moon and Jupiter where meteor impacts have been observed as they occur. The meteoroids at Saturn are estimated to range…
What would it look like to watch Daphnis fly past?
Maybe something like THIS: What a great combination: Daphnis (my favorite moon) and an artist’s interpretation of what it might look like to see it whiz past as it travels around Saturn inside the Keeler Gap, sending up waves in the rings as it goes! The image is by Erik Svensson, who came across my recent…
Research Reveals Rain Shadows from Saturn’s Rings
A rain of ionized water molecules falls into Saturn’s upper atmosphere from its rings, researchers from England’s University of Leicester have found. Using images from NASA’s Voyager spacecraft and more recent near-infrared observations from the Keck Observatory in Hawaii, it has been found that dark bands seen across Saturn are actually the “rain shadows” of…
Enceladus is Spraying Its Salty Sea Out Into Space
Thanks to Cassini we’ve known about the jets of icy brine spraying from the south pole of Saturn’s moon Enceladus for about 8 years now, but this week it was revealed at the 44th Lunar and Planetary Science Conference outside Houston, Texas that Enceladus’ jets very likely reach all the way down to the sea — a salty…
Highlighting Rhea’s Subtle Colors – New Cassini Images of Saturn’s Moon
This is a color composite image of Rhea (pronounced REE-ah) I made from raw images acquired by the Cassini spacecraft on March 9, 2013, during its most recent — and final — close pass of the moon. The visible-light colors of Rhea’s frozen surface have been oversaturated to make them more apparent… even so, it’s…
The Colors of Saturn’s Northern Skies
Bored by blue? Saturn’s skies sure do have a lot more colors, as seen here in a color-somposite made from raw Cassini images acquired on Feb. 27, 2013. With spring progressing on Saturn’s northern hemisphere (a season that takes 7 1/2 Earth years to pass!) the upper latitudes gradually receive more sunlight and thus more…
Ghosts of Worlds Passed
Saturn’s F ring is a fascinating structure. Made of fine icy particles — most no larger than the particulates found in cigarette smoke — it orbits Saturn just outside the A ring and is easily perturbed by the gravity of nearby moons and embedded moonlets, which create streamers and clumps that rise up in fanciful…
