Amazing photos have just come back from Cassini, of swirling clouds surrounding Saturn's north pole.

On Saturday, while parked for the Thanksgiving holiday at the edge of Glenelg, Curiosity took a lovely panorama pointed to the east and into Glenelg.

After a false start earlier this year, the first chunk of Dawn Framing Camera data from Vesta has finally made it to the Planetary Data System. As a first step to understanding the data set, I've built some index pages to these cool images.

This is a very large (19000 pixels square) mosaic of the fjords and glaciers of southern Greenland. I had been interested for a long time in experimenting with the processing of Earth satellite imagery just to get a comparison to the other planets.

I asked Mars Reconnaissance Orbiter to take a photo, and it turned out better than I had imagined: an incredibly fresh, well-preserved, dramatically rayed oblique impact crater.

A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.

Today I stumbled upon the Lunar and Planetary Institute's Lunar Sample Atlas, and was reminded of how much I love petrographic thin sections. They can make unassuming, cruddy looking rocks beautiful.

Curiosity used MAHLI, the scientific camera at the end of the robotic arm, to shoot a huge color portrait of herself sitting on Mars, with Gale's central mountain in the background.

Curiosity has already spent more than three weeks at Rocknest, working through the very slow process of commissioning the sample handling systems. While parked, she's taken a couple of amazing photo mosaics.

Today hurricane Sandy is a major threat to life and property across the west coast of the northern Atlantic ocean. I just want to give thanks in advance to all the people who have devoted their careers to making sure that Americans have sufficient warning of devastating, unstoppable weather events like this one.

From the Cassini data archives comes a huge (5000 pixels square!) color image of Saturn's icy moon Dione, worth investigating from both near and far.

The landscapes that surround Curiosity are picture-postcard beautiful.

Curiosity shot a lovely panoramic view of the distant rim of Gale crater in the dramatic lighting of late afternoon on sol 49. Damien Bouic has colorized it, and it is beautiful.

The newly-released eXtreme Deep Field takes us even further back into the history of our universe than the Ultra Deep Field or UDF.

It's a quarterly feast day for me: the day that the Cassini mission delivers three months' worth of data to NASA's Planetary Data System. Here's a few images processed from the October 1, 2012 data release.

Curiosity has been shooting photos of the Sun as Phobos and Deimos cross its face, and -- as far as I can tell -- captured sunspots as well.

A beautiful panoramic view of the varied rocks of Glenelg has been transmitted from Curiosity on Mars. But before going any further, it's time to run the first Martian sand through the soil sampling system.

Curiosity has successfully photographed a crescent Phobos in a bright daylit Martian sky.
