Hi all,
Phil Plait's got a new article up on Slate with a gorgeous composite image of the martian North Pole, courtesy Mars Express. After sharing it around, I got into a conversation with a friend who posited that the "watercolour" look of the image came from averaging so many overlapping frames, thus removing a lot of high-frequency noise. My own intuitive answer was that we're actually seeing the difference between the dusty and uneven martian ground, and the wind-polished ice above it. I figured I knew of some folks who might have more to say on the subject... Thoughts? Counter-arguments? Either way, it's just one amazing image. |

Ah, you're probably right -- something along the lines of "like an abstract painting" would have been closer to what I had in mind. Whichever way you slice it, though, it's still some pretty stunning terrain.
Thanks for the welcome |
