Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.
A Mars imaging scientist answers the question: who is the "photographer" behind images returned from Mars?
A few days ago, the Dawn mission finally published their archival data. During the year of delay I often looked with anticipation to the Planetary Data System to check whether or not images were there, and I am delighted that they are finally available. Was the wait worth it? Definitely!
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.
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.
New ground-based images of Uranus show more finely detailed structure than any photos I have ever seen.
Space blogger Daniel Fischer writes about the problem of composited astrophotos being distributed through social media channels by people unaware that they are artworks, not documentary photographs.
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.

I noticed today that I hadn't seen any amateur-processed versions of Voyager's departing shots of Uranus, so I decided to give it a try.
So far, the only high-resolution surface panorama we've seen from Curiosity is the black and white Navcam image. The Mastcam shot a color panorama, but the only version we have so far was created from the lower-resolution thumbnails.
A paper conservator at an art museum explains how scientific analysis of artworks using different parts of the electromagnetic spectrum is informing understanding of how the artists worked, and how the appearance of their pantings has changed with time.
Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.

Whether you heard the show or not, you'll be fascinated by Emily's great presentation. It also proves she is not part of the great conspiracy that is hiding evidence of alien bases on the moons of Saturn!

Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.
