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.

This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.

Daniel Macháček has colorized some terrific images of Phobos and run them through some morphing software to make a seamless animation that appears to show Phobos rotating before you.

If I have to, I will drag reluctant people one at a time to plunge into NASA's Planetary Data System.

In response to Emily's entry about finally getting her hands on a subscription to the planetary science journal Icarus, I thought I would report on an article from the most recent issue: Geology of the Selk crater region on Titan from Cassini VIMS observations, by Jason Soderblom and 11 other scientists.

Venus? What? Somebody still studies that planet? Yes, and in fact there's an active spacecraft there: Venus Express, the poor little sister to Mars Express.
