Saturn’s Skyline

A raw image from Cassini taken on January 9, 2011, this minimally-composed image is actually quite fascinating (IMO): it’s a look at the upper levels of Saturn’s atmosphere in methane wavelength! Yes, Saturn is a gas giant and most of its volume is made up of hydrogen and helium, but there are layers of its…

Lines of Light

The line of Saturn’s edge – or “limb” – glows brightly with backlit sunlight, as do its rings, in this wonderful image from Cassini, color-calibrated by Gordan Ugarkovic. Beige and blue colors can be seen in the layers of Saturn’s upper atmosphere, and the distant arc of the rings seem to sink into this before…

A Saturn-Sized Storm

Earlier this week the Cassini spacecraft captured this image of an eddying storm in Saturn’s northern hemisphere. Nearly as large as the Earth, the bright clouds have been visible to amateur astronomers for several weeks and on December 27 Cassini was able to get a nice view of its own from orbit! Fantastic. See more…

Blowing off Steam

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

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 – most noticeably…

Dione and Tethys in Passing

Two of Saturn’s moons pass each other from Cassini’s perspective on December 6, 2010, in this animation compiled from 70 raw image files. This was more an experiment in using iMovie HD to create an animation from a lot of individual images than anything else…I didn’t take the time to clean up the specks and…

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 180º (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’s upper 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 the Cassini mission are my personal favorites and make up more than half of all my posts. So you can imagine my dismay when Cassini went into a “safe” mode over the past…
