Lightning on Jupiter / Dr Michael H. Wong (SETI Institute; Department of Astronomy, UC Berkeley)

Abstract: Lightning signals of different types have been detected by every
spacecraft that visited Jupiter since Voyager in 1979. The Juno
mission currently in orbit around Jupiter has returned a wealth
of new data on lightning phenomena. Juno's Microwave Radiometer
has detected thousands of radio bursts known as "sferics." Given
the distance to the spacecraft and the frequency of emission, the
signals imply an incredibly powerful source strength, comparable
to the rarest high-energy events in terrestrial storms. As on
Earth, Jupiter's lightning is more common in some locations like
cyclonic belts and storms---but rare in other locations---
revealing that heat transport by convection is not
homogeneous. Combining Juno and HST data reveals the cloud
structure in storms associated with intense clusters of sferics.
Juno has also discovered UV emissions that may resemble
terrestrial sprites, and shallow lightning that may require
exotic "mushballs" composed of a slush of ammonia and water ices.
