Mars - Aeolian Sand Dunes
The study of "formed-by-wind" landforms is called Aeolian geology. Mars offers some amazingly intricate and beautiful aeolian shapes. NASA's HiRISE spacecraft, with its super sharp color imaging, has given us this fantastic, false color image of just a sample of some of the amazing "formed-by-wind" beauty on Mars. Like many other images in our gallery, this one in particular invokes a strong modern-art feel as well, adding to the "science as art" theme.
