Get your 3-D glasses (the red-and-green kind) ready, we’re going on a trip to Mars.

Let your gaze drift across this anaglyph of the dunes of Nili Patera taken from NASA’s HiRISE camera aboard Mars Reconnaissance Orbiter. HiRISE images many targets twice, within seconds of each other, so scientists can see a location from different angles. The images are used to make more accurate maps. Only problem is, dunes move, making the job of a Mars mapper a little difficult.

Besides making a beautiful, but sometimes eye-bending, picture, th...
