Ball lightning is a rare circular light phenomenon occurring during thunderstorms. Scientists have been puzzled by the nature of these apparent fire balls for a long time. Now physicists have calculated that the magnetic field of long lightning strokes may produce the image of luminous shapes, also known as phosphenes, in the brain. This finding may offer an explanation for many ball lightning observations.
