There's a Secret Message Written Into the Sands of Mars

NASA has spotted something strange and beautiful in the sands of Mars—a remarkable dune field that looks eerily similar to Morse code. And it has a message for us.

According to Veronica Bray, the Hi-RISE targeting specialist who analyzed the image, dot and dash features like these have been spotted on Mars before. But in this photo of the Hagal Dune field just south of Mars’ north polar cap, the code-like pattern is especially clear due to unusual topography. Specifically, a nearby circular depression (probably a sand-filled impact crater) has “focused the wind, and also limited the amount of sand available for formation of the dunes,” Bray told Gizmodo.
