Cassini gives Dione a close shave

December 13, 2011 | By

The Cassini spacecraft has been touring Saturn and its moons for 7 years now, and yet still manages to send back images that are simply astonishing. Just yesterday, the probe swung past the icy moon Dione at a distance of just 99 kilometers (62 miles) over the surface! Compare that to the moon’s diameter of […]

Cassini visits a foamy moon

August 26, 2011 | By

I’ve said it before: Saturn’s moon Hyperion is seriously freaky. New images from the Cassini spacecraft flyby of the tiny moon don’t change my mind one bit: [Click to enchronosenate.] What a weird place! Hyperion is a lumpy chunk of ice only about 270 km (170 miles) across on average, but yesterday (August 25, 2011) […]

The stark beauty of Cassini's Saturn

June 2, 2011 | By

Speaking of Cassini… The spacecraft has been orbiting Saturn for nearly 7 years now, and has returned many thousands of images of the rings, moons, and planet back to Earth. Many times, the images are part of a series — tracking the large moon Titan, for example, or following one of the outer, faint rings […]

Cassini's pentaverate

June 2, 2011 | By

I haven’t posted a Cassini picture in quite some time. To make up for that, here’s a stunner of a family portrait showing five worlds! [Click to enchronosate.] This shot shows Saturn’s rings nearly edge-on, but dominating the scene is Rhea, 1500 km (950 miles) in diameter, seen here 61,000 km (38,000 miles) distant. Below […]

Video of Cassini's Hyperion flyby

December 4, 2010 | By

Yesterday, I posted some beautiful still images from the Cassini spacecraft’s flyby of Hyperion, a weird moon of Saturn. To research the images I posted (mostly to find out how far Cassini was from Hyperion when the images were taken), I went to the Cassini raw image archive, and saw dozens of such images. My […]

Cassini's slant on the rings

July 2, 2010 | By

Check out this latest image from Cassini at Saturn! [Click to embiggen.] Oh, wow! This was taken when the spacecraft was almost in the plane of the rings, which are incredibly thin. You can see several different rings, including the broad A ring in the middle and the thin F ring on the outside. There […]

Cassini eavesdrops on orbit-swapping moons

April 8, 2010 | By

The Cassini spacecraft just had a few close encounters with some of the odder moons in the Saturn system… and given how weird Saturn is, that’s saying something. I was particularly enthralled with these two small worlds: On the left is the moon Janus and on the right is Epimetheus. The scales are not quite […]

Cassini: Ten years since Jupiter

January 25, 2010 | By

Just a hair over ten nine years ago, the Cassini spacecraft caromed past Jupiter, stealing a tiny bit of the giant planet’s energy to hasten the space probe’s journey to Saturn. When it passed Jupiter at a distance of about 10 million kilometers (6 million miles), Cassini saw this: [Click to enjovianate. Seriously, the full-res […]

Cassini takes home video of Saturn's aurora

November 24, 2009 | By

Cassini keeps amazing me, even when I start to think I’m getting used to incredible images beamed back from Saturn. But this is new: it took several images of Saturn’s aurora, and strung them together to make a video! Here’s a still frame: The outline of Saturn is there, along with some latitude lines for […]

Cassini buzzes Enceladus once again

November 21, 2009 | By

On November 20, 2009, the Cassini spacecraft buzzed the surface of Saturn’s icy moon Enceladus once again, returning dramatic images of its water geysers and wrinkled, ridged surface: That raw image (which means it has not been processed to remove instrument/detector artifacts like bad pixels and such) was taken when Cassini was a mere 2000 […]
