It's been awhile since we've had some rock discussions but today's Bing wallpaper really interests me. No ide where this is from but I'm hoping one of out far more knowledgeable folk can explain what is seen in the image.
The stark contrast between the story on the right and left must really be pretty simple but I'd love to hear from one of our geologists. My current guess is that the clue to explaining all of this is seen at the upper right side.
Those structures there in the background look familiar. They remind me of some similar I used to see a lot on Earth. Either the Encyclopedia Galactica or The Hitchhiker's Guide can tell you where that planet is. But, I can tell you it isn't Gallifrey. Good luck.
