NASA’s Curiosity Mars rover captured this feather-shaped iridescent cloud just after sunset on Jan. 27, 2023. Studying the colors in iridescent clouds tells scientists something about particle size within the clouds and how they grow over time. These clouds were captured as part of a seasonal imaging campaign to study noctilucent, or “night-shining” clouds. A new campaign in January 2025 led to Curiosity capturing this video of red- and green-tinged clouds drifting through the Martian sky.

NASA的好奇号火星探测车在2023年1月27日日落后拍摄到了这朵羽毛状的彩虹云。研究这些云层中的颜色可以帮助科学家了解云粒子的大小及其随时间的变化。这些云是季节性成像任务的一部分，旨在研究夜光云（Noctilucent Clouds），即“夜间发光的云层”。在2025年1月开展的新一轮观测任务中，好奇号成功拍摄到红色和绿色光晕的云层在火星天空中飘动的视频。
