Why the Length of Saturn's Day Is So Hard to Measure 

The length of a planet's day seems like such a simple number, a basic piece of information that should accompany any solar system diagram. But probes flying past Saturn have turned up oddly conflicting numbers. » 3/25/15 5:00pm 3/25/15 5:00pm

Look How Tiny Saturn's Moon Prometheus Is

This may just be another glorious picture of Saturn's rings—but it also serves to show just how large the planet is. Can you make out its moon Prometheus in the image? » 3/17/15 3:45am 3/17/15 3:45am

It's Time to Go Alien Hunting on Titan

Move over Europa, there's another moon out to claim the title of first place we'll discover extraterrestrial life. New research from Cornell University finds that alien microbes could, just maybe, eek it out on Saturn's largest moon, Titan. But these critters wouldn't be like anything we've ever seen before—not even… » 3/01/15 4:00pm 3/01/15 4:00pm

The mysterious eye of the cosmos is watching you

NASA's Astronomy Picture of the Day is back with a winner: Saturn's crescent phase captured by Cassini with its rings and the moon Rhea. It looks like a menacing eye from a colossal evil being from another dimension opening in the darkness of space, watching all of us. There's an amazing movie too: » 1/08/15 10:23pm 1/08/15 10:23pm

Two-mile-high structures rising on Saturn's rings

Someone on Reddit posted this old November 2010 image by the Cassini spacecraft. It shows 2-mile-high (3.5-kilometer) structures rising on Saturn's B ring's outer edge. We talked about this back then, but it's a great peg to show this cool artist impression of what it would look like from the ring itself: » 12/29/14 11:33pm 12/29/14 11:33pm

Impressive new image of Saturn from above the ecliptic plane

Our friend Val Klavans sent me a Christmas present this morning: A color photo of Saturn as you would have seen it if you were riding the spacecraft Cassini on December 21, 2014. Saturn's north polar hexagon stands out prominently while the rings encircle the planet. You can see the hexagon storm on its north pole. » 12/25/14 4:46pm 12/25/14 4:46pm

Why Orion's launch is the best news for humanity in a long time

I have always been sad that I never got to see the beginning of humanity's ultimate journey—and even sadder to realize that in 1972 we abandoned a path that could have possibly gotten us to other planets by now. On December 5, 2014, we opened the gate to that path again. We should rejoice—we are going back to the… » 12/05/14 8:57am 12/05/14 8:57am

Saturn's two largest moon—Rhea and Titan—line up for the Cassini orbiter. Rhea's pock-marked surface provides a beautiful contrast to the golden glow of Titan—though they're both actually made up of largely similar material. [ESA] » 11/04/14 6:40am 11/04/14 6:40am

One of Saturn's Moons Could Have a Subterranean Sea

NASA scientists have been taking a closer look at Saturn's moon Mimas thanks to Cassini's roving eyes, and they've made an interesting discovery: it could have an ocean of water beneath its surface. » 10/17/14 6:45am 10/17/14 6:45am

Saturn moon looks like a wasp nest and it may freak some people out

Check out this stunningly crispy photo of Saturn moon's Hyperion—taken by the Cassini spacecraft. Apparently it is inhabited by alien wasps the size of cars or at least it looks like a wasp nest to me. So gross!* New analysis of Cassini's data reveal that, if there are giant alien wasps, they are producing electrons. » 10/16/14 10:04pm 10/16/14 10:04pm

Not quite the Moon on a stick, but not far off. This is Tethys, one of Saturn's icy moons, from a perspective that makes it look like it's stuck to the A and F rings of the planet. [NASA] » 10/15/14 7:30am 10/15/14 7:30am

Titan Has a Huge Toxic Cloud Swirling Over Its South Pole

If you're thinking of heading off on a spacecation, can we recommend that you don't visit Titan's south pole. Because not only is it cold and stormy—but new research also reveals that it's toxic, too. » 10/02/14 6:45am 10/02/14 6:45am

Behold the awesome nebulae flybys in this new In Saturn's Rings teaser

Our friends of In Saturn's Rings have a new teaser for their incoming 4K IMAX grand tour of the Universe, made using millions of high definition photographs taken by telescopes and spacecraft. There are no 3D models in these videos. Just photos, animated by 67 volunteers from all over the world. » 9/17/14 7:48pm 9/17/14 7:48pm

Cool history of evolution turns lifeforms into robots

This ad for the German technology store Saturn makes as much sense as a Transformers movie: Zero. But I like how it tells the evolution of life on Earth making a parallel with the evolution of human technology. » 8/21/14 8:29pm 8/21/14 8:29pm

You get three-for-one in this striking image of Saturn: its north polar vortex and hexagon along with its expansive rings. It was captured by Cassini's wide-angle camera earlier this year. [NASA] » 7/09/14 7:23am 7/09/14 7:23am

The 50 Most Amazing Images From a Decade of Orbiting Saturn

Cassini entered Saturn's orbit on July 1st, 2004. And ever since, this NASA-ESA-ASI collaboration has delivered stunning images of the crown jewel of our solar system. The following 50 images were chosen from thousands of similarly great photographs from a full decade of exploring the sixth planet and its iconic ring… » 7/01/14 4:00pm 7/01/14 4:00pm

NASA's smell-o-scope experiment sniffs Saturn's moon Titan

Good news, everyone! NASA has came up with an interplanetary smell-o-scope experiment, processing data from the Cassini spacecraft and reproducing the smell of another world right here on Earth: Saturn's moon Titan. (Spoiler: It stinks.) » 6/13/14 8:34pm 6/13/14 8:34pm

A beautiful photo of Saturn taken last Monday

Our friend Val Klavans sent us this beautiful image of Saturn in approximate true color, taken on May 5 by Cassini. This is how your eyes would see it if you were there looking down from a high angle, at approximately 1,837,403 miles (2,957,013 kilometers) away from the planet. » 5/07/14 10:23pm 5/07/14 10:23pm
