Behold: Daphnis, the tiny, 8-kilometer moon that orbits within a ring gap, gently tugging on the edges of the gap to create delicate scallops.

Serene Saturn (or the “Glutton for Punishment” mosaic)

Ian Regan • November 08, 2016

A week ago Saturday I decided -- against my better judgment -- to tackle this monster of a mosaic. I call it the "Glutton for Punishment" mosaic.

Three bright planets: Portraits from the Pyrenees

Emily Lakdawalla • May 26, 2016

It's a great time to go outdoors and look at planets. I have three glorious planetary portraits to share today, sent to me by amateur astronomer Jean-Luc Dauvergne.

Watch the entire Cassini mission image catalog as a movie

Emily Lakdawalla • November 20, 2015

If you were to download the entire catalog of photos taken at Saturn to date by Cassini and then animate them like a flipbook, how long would it take to watch them all pass by? The Wall Street Journal's Visual Correspondent Jon Keegan has your answer: nearly four hours.

A few gems from the latest Cassini image data release

Emily Lakdawalla • April 24, 2015

I checked out the latest public image release from Cassini and found an awesome panorama across Saturn's rings, as well as some pretty views looking over Titan's north pole.

Prometheus, Pandora, and the braided F ring in motion

Emily Lakdawalla • March 23, 2015

On the masses and motions of mini-moons: Pandora's not a "shepherd," but Prometheus still is

Emily Lakdawalla • July 04, 2014

As Cassini celebrates 10 years at Saturn, we're beginning to see its long-term observations of Saturnian moons bear fruit. A surprising new result: While Prometheus exerts control over the F ring and Atlas, Pandora -- long thought to be a shepherd of the F ring -- does not.

Of Rings and Resolution

A little fun with Cassini rings images

Emily Lakdawalla • February 25, 2014

It's happened again; I went into the Cassini image archive looking for something specific and wound up spending several hours playing with totally unrelated image data. Here are several beautiful images of the rings from the archives.

Just what is going on in that magnificent Cassini image of Saturn?

Emily Lakdawalla • November 13, 2013

It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.
