Nearly four decades before Curiosity, we dug into Mars for the first time. The pictures are still amazing.

Look past the rings, and Saturn is even stranger--and more breathtaking.

Last week I trawled the archives to find all of Galileo's images of asteroid Ida; this week, I turned to Gaspra.

Nineteen years ago this month, the Clementine mission sent some amazing views from the moon.

While writing up the cruise-phase issues of the Galileo Messenger a couple of weeks ago, I came across a fuzzy montage of images of Ida that I had not seen before. So I decided to spend some time digging into the Planetary Data System to see if there were more images to be found. I found lots and lots pictures that I'd never seen before!

When the sunlight catches it just right, Saturn's F Ring is something to see.

Damien Bouic received some well-deserved recognition from the Chemcam team for his great Curiosity image processing work.

Why spend effort and scarce resources on space exploration when we have so many problems here at home? Turns out, there are some pretty good reasons.

With the Landsat Data Continuity Mission scheduled to launch on Monday, there's been a lot of Tweeting about Landsat, and through one such Tweet I learned about a resource that I hadn't known existed before: the LandsatLook Viewer. This is a graphical interface to more than a decade worth of Landsat data, a tremendous resource for anyone interested in Earth's changing surface, natural or manmade.

On a lonely evening, what is one to do but to dip into archival space image data and surface with a gorgeous photo of a crescent Neptune and Triton?

For the first time, amateur astronomers are capturing spectacular images of Saturn's bizarre north polar hexagon.

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.

Just like on Earth, clouds and storms often ripple through the Martian atmosphere. You can even check the daily weather report.

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

Last week at a meeting of NASA's Small Bodies Assessment Group (SBAG), Han Li of the Chinese Academy of Sciences gave a lengthy presentation on Chang'E 2. Her presentation included a new sequence of photos from the December 13 Toutatis flyby.

My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.
