白天，在中国甘肃省敦煌附近的戈壁沙漠西部边缘，超过12000面大镜子反射着100兆瓦的熔盐太阳能热电厂的阳光。独立的镜面面板像向日葵一样转动以跟踪太阳。它们合谋充当一个单一的超级镜子，将阳光反射到一个固定的位置，即电站的中心塔。然而，在夜间，镜子一动不动地站着。它们反射了无数遥远的恒星、星团和银河系内外星云的光。这幅科幻夜景是9月15日用相机固定在巨大镜面矩阵边缘的三脚架上拍摄的。相机的组合数码曝光序列捕捉到了夜空中星光轨迹的同心弧线，星光轨迹在超现实的镜像反射中呈现出来。

During the day, over 12,000 large mirrors reflect sunlight at the 100-megawatt, molten-salt, solar thermal power plant at the western edge of the Gobi desert near Dunhuang, Gansu Province, China. Individual mirror panels turn to track the sun like sunflowers. They conspire to act as a single super mirror reflecting the sunlight toward a fixed position, the power station's central tower. During the night the mirrors stand motionless though. They reflect the light of the countless distant stars, clusters and nebulae of the Milky Way and beyond. This sci-fi night skyscape was created with a camera fixed to a tripod near the edge of the giant mirror matrix on September 15. The camera's combined sequence of digital exposures captures concentric arcs of celestial star trails through the night with star trails in surreal mirrored reflection.
