For centuries, ball lightning has captured the imagination of witnesses and defied scientific explanation, but now Chinese scientists have managed, by sheer chance, to capture an example of the mysterious lights on camera.
The image was actually obtained in 2012, in the Qinghai region of China, by researchers observing lightning during a thunderstorm using just a simple video camera in conjunction with a spectrometer, a device that used to measure the components of different types of light in order to identify the substances that may have produced it. The camera recorded a sizeable spark of ball lightning measuring 16 feet wide, which glowed continuously for about 1.6 seconds and floated for a distance of some 50 feet.
