BigPic: What Does This Photo, Taken From The ISS, Show?

Where on Earth...?

Chris Hadfield on Twitter

Canadian astronaut and expedition commander Chris Hadfield shared this photo from the International Space Station today. He thought it looked like "mouthwatering generous folds of icing"; to me, it looked more like a slice of walnut-studded cake. It's actually a photo of sand dunes in Saudi Arabia.
