Lightning can produce special waves of energy RooM the Agency/Alamy An overlooked mechanism lets energy from lightning reach the highest layers of the atmosphere, where it could threaten the safety of satellites and astronauts. When lightning occurs, the energy it carries sometimes gives rise to special electromagnetic waves called whistlers, so named because they can
