Lightning is as beautiful as it is powerful – a violent, hotter than the surface of the Sun electrical marvel. But might lightning on other planets be even more astonishing?  Consider this. When Voyager 1 flew by Jupiter in 1979, its imager captured areas nearly as big as the U.S. lit up by... Read More
