Mimas, Dione, Rhea

Emily Lakdawalla • May 31, 2007

There's been quite a lot of Mars on this page for the last week; it's time to remind ourselves that there are other places besides Mars in the solar system.

Many Cassini views of Tethys

Emily Lakdawalla • May 21, 2007

Here we bring you fifteen different Cassini views of the same world, a cratered ball of ice called Tethys.

Cassini observes a new face of Iapetus

Emily Lakdawalla • April 20, 2007

Cassini has just begun its 44th orbit of Saturn (called Rev 43), and is starting it off with lots of views of famously two-faced Iapetus.

LPSC: Tuesday: Volcanism and tectonism on Saturn's satellites

Anne Verbiscer • March 14, 2007

I received this report on the Tuesday afternoon special session on volcanism and tectonism on Saturn's satellites from Anne Verbiscer, an astronomer from the University of Virginia who I first met at the Division of Planetary Sciences meeting in 2005.

Cassini's global views of Saturn and its rings

Emily Lakdawalla • March 08, 2007

New Horizons sees Io erupting!

Emily Lakdawalla • February 27, 2007

There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!

Saturn from above, in color

Emily Lakdawalla • January 31, 2007

I wrote recently about a set of images of Saturn acquired by Cassini from a unique vantage point, well above the planet, looking down on the rings. Someone has taken up the challenge of assembling the 36 different images into a single mosaic, in color, and it is as lovely as I'd hoped.

New Horizons' raw images are now online

I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.

The Saturn view I've been waiting for

Emily Lakdawalla • January 22, 2007

Over the weekend, Cassini acquired a set of images that will (I am assuming) eventually be used to produce a glorious portrait of the ringed planet from a point of view that's never been seen before.
