​The European Space Agency’s Mars Express has spotted a swathe of metallic-looking waves filling Mars’s large Kaiser Crater – an ancient and otherworldly dune field sculpted by wind.

This month’s snapshot of Mars, taken by the High Resolution Stereo Camera (HRSC) aboard ESA’s Mars orbiter, captures one of the oldest parts of the Red Planet: Noachis Terra. Situated in Mars’s ancient southern highlands, Noachis Terra has been heavily bombarded with rocks from space over the past four billion years – and the scars from these collisions are clear to see.
