Explanation: If you see this as a monster’s face, don’t panic. It’s only pareidolia, often experienced as the tendency to see faces in patterns of light and shadow. In fact, the startling visual scene is actually a 180 degree panorama of Northern Lights, digitally mirrored like inkblots on a folded piece of paper. Frames used to construct it were captured on a September night from the middle of a waterfall-crossing suspension bridge in Jamtland, Sweden. With geomagnetic storms triggered by recent solar activity, auroral displays could be very active at planet Earth’s high latitudes in the coming days. But if you see a monster’s face in your own neighborhood tomorrow night, it might just be Halloween.

说明: 如你所见为怪物的脸谱，别慌。它不过是空想性错视，为人们在见到亮暗图案时，通常会辨识成某种脸谱的倾向。在此例里，这片触目惊心的光影，其实是宽为180度的北极光全景，后来再经过类似折纸墨迹蘸印式的数位镜面复制。而用于建构这幅影像的多幅照片，则是在今年9月的某个夜晚摄于瑞典耶姆特兰省一座跨瀑布的吊桥上。在接下来的这数天里，由于最近有太阳活动所触发的地球磁暴，地球高纬度地区可见到很活跃的极光活动。不过，如果你明晚在住家附近见到怪物脸谱，可能的原因为万圣节。 （Rorschach Aurora 罗夏克墨渍极光）
