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.

Red-and-green-tinted clouds drift through the Martian sky in a new set of images captured by NASA's Curiosity rover using its Mastcam—its main set of "eyes." Taken over 16 minutes on Jan. 17 (the 4,426th Martian day,

"I'll always remember the first time I saw those iridescent clouds and was sure at first it was some color artifact."

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,

NASA’s Curiosity rover has captured breathtaking images of iridescent clouds drifting across the Martian sky, revealing a celestial spectacle unlike anything seen before. These clouds, composed of frozen carbon dioxide ice,

NASA has released stunning images of mysterious colorful clouds drifting in the sky over Mars. Captured by NASA's Curiosity rover on January 17 over the course of 16 minutes, the images show noctilucent,
