NASA rover captures images of mysterious "mother-of-pearl" clouds above Mars
New images captured by NASA's Curiosity rover show colorful clouds in the sky over Mars. The images were captured by the rover's Mastcam, which NASA's Jet Propulsion Laboratory compared to the rover's eyes. The clouds were spotted on Jan. 17, and the photos were taken over the course of 16 minutes, the space agency said in a news release.
