   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.
