"This is the first time we have the visible lightning flash together with the radio data," said Georg Fischer, a radio and plasma wave scientist at the Space Research Institute in Graz, Austria.
The difficulty with seeing lightning on Saturn is the visual obstruction caused by the planet's rings which reflect sunlight and obscure the flashed from storms on the surface. The first images capturing lightning on Saturn were taken in August 2009 during a storm that lasted from January to October of that year. The images used for the video were much brighter and were taken during a later storm in November 2009. The areas lit by the lightning flashes are approximately 300 km in diameter.
