The iridescent cloud reveals new clues about ice formation in the Martian atmosphere (no little green men, sorry).

Curiosity, a set of NASA 's robotic "eyes" on the Red Planet, recorded 16 minutes of so-called noctilucent clouds flying overhead on Jan. 17. These clouds, sometimes referred to as twilight clouds because they're too faint to see in daylight, appear iridescent by scattering light from the setting sun.

NASA’s Curiosity rover has captured breathtaking images of red and green-tinted clouds drifting across the Martian sky. These clouds, called noctilucent clouds (which means “night shining” in Latin), appear at twilight and are visible because the setting sun scatters light through them.

At the surface, Mars is a desolate, barren world with a rocky landscape, massive dust storms and extreme temperature swings. However, a rover recently captured a splash of color in the sky as rare clouds drifted overhead.
