Mighty Optical Illusions

Aurora Borealis

Mike Hollingshead is s storm chaser from Nebraska. Just came across some of his amazing aurora images via digg. They sure look unreal! For thos of you who didn’t know, Aurora is a glow in the night sky. It is also known as “aurora polaris” or in northern latitudes, as “aurora borealis” or “northern lights”. It is caused by electrons of typical energy obtained by the electrons passing through a voltage difference. The light is produced when they collide with atoms of the upper atmosphere. Here are some of Mike’s photographs, but be sure to visit his website for whole-lot-more of them! Image below gave me impression of a Ghost Ship comming out of the fog!
