Martian illusion




NASA/JPL/University of Arizona.
This image taken by NASA's Mars Reconnaissance Orbiter shows an optical illusion. What appear to be trees rising from the Martian surface are actually dark streaks of collapsed material running down sand dunes due to carbon dioxide frost evaporation. The image, taken April 7, 2008, was released Jan. 11.
