Awesome Cassini mutual event movies

Emily Lakdawalla • December 23, 2009

I love posting animations of Cassini images that I compose from frames grabbed from the mission's raw images website, but they are shoddy compared to the versions that eventually come out from the mission's imaging team.

Awesome Mars Express view of Phobos and Deimos together

Emily Lakdawalla • December 11, 2009

My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a "mutual event."

Planetary Society Advent Calendar for December 9: Atlas

Emily Lakdawalla • December 09, 2009

Here's another weird-looking one, though it's less weird from this particular, polar point of view than it is when viewed from the side.

Planetary Society Advent Calendar for December 5: Epimetheus

Emily Lakdawalla • December 05, 2009

Epimetheus is one of the many small moons of Saturn that are referred to by the Cassini mission team as "rocks" though they are probably mostly made of ice, not rock.

Four moons and a ring

Emily Lakdawalla • November 10, 2009

Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

Another marvelous image from Cassini's Nov 2 Enceladus flyby

Emily Lakdawalla • November 03, 2009

This image goodie was produced from the raw images from Cassini's close encounter with Saturn's geyser moon Enceladus yesterday by Gordan Ugarkovic.

The Phoebe ring

Emily Lakdawalla • October 14, 2009

Last week, planetary astronomers Anne Verbiscer, Michael Skrutskie, and Doug Hamilton published a paper in Nature succinctly titled "Saturn's Largest Ring." In the paper, they announce the discovery, using the Spitzer infrared space telescope, of a gargantuan, previously unseen ring around Saturn, encompassing the orbit of Phoebe.

Canto III: Hints of Equinox

David Seal • June 04, 2009

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

Many, many views of Saturn's moons

Emily Lakdawalla • February 10, 2006

Another thing I've been trying to catch up on is the daily imaging activities of Cassini, but that, too, has been tough because Cassini has been taking so dang many pictures!

The Orbital Dance of Epimetheus and Janus

Emily Lakdawalla • February 07, 2006

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.
