The 1st ever x-ray images of lightning have been captured, using a super fast x-ray camera. Meahan Schaal from Florida Institute of Technology in Melbourne, Florida is the creator of this x-ray cam which weighs about 1500 pound.
It consists of an x-ray detector housed in a box about the size and shape of a refrigerator. The box is lined with lead to shield the x-ray detector from stray radiation. X-rays enter the box through a small hole that in turn focuses them, like an old-fashioned pinhole camera.
Camera can also be used to take 10 million pictures per second.
