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.
How does the LRO lunar map compare with the new Chinese product from Chang'e 2?

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.

The Dawn mission to Vesta continues to release an image every day, and recently they have been releasing lots of color images. I like color pictures for aesthetic reasons, but color is actually a very important property of planetary surfaces.

Two weeks ago I posted an awesome video of Martian clouds in motion. Last week I explained how I accessed the Mars Express images that comprise the animation. Today I'm going to explain how I turned the five-frame animation of Mars Express images into a smooth movie.

Last Friday I posted an awesome video of Martian clouds in motion. This week I'll tell you how I made it. The how-to is split up into two parts. The first, today, is how to access Mars Express HRSC image data and process it into the individual animation frames, from which you can make an animated GIF.

Saturn's raging northern storm has been watched since it began by amateur astronomers, and now Cassini is getting in to the act too. Presumably once astronomers realized the magnitude of what was going on, some of Earth's great observatories were also occasionally pointed at the ringed planet to watch the storm grow.
