Until now, evidence for lightning on Saturn has been indirect – through radio emissions and cloud morphology. Here we report the first visible detection of lightning, on the night side on August 17, 2009 at −36.4° ± 0.1° planetocentric latitude and 10.6° ± 0.9° west longitude. No other locations produced lightning detectable by either imaging or radio. The lightning images are consistent with a single cloud flashing once per minute. The visible energy of a single flash is comparable to that on… 
Overview of Saturn lightning observations
The lightning activity in Saturn's atmosphere has been monitored by Cassini for more than six years. The continuous observations of the radio signatures called SEDs (Saturn Electrostatic Discharges)
A giant thunderstorm on Saturn
TLDR
Observations of a giant thunderstorm at planetocentric latitude 35° north that reached a latitudinal extension of 10,000 kilometres about three weeks after it started in early December 2010, which developed an elongated eastward tail with additional but weaker storm cells that wrapped around the whole planet by February 2011.
Analysis of a long-lived, two-cell lightning storm on Saturn
Lightning storms in Saturn’s atmosphere can last for a few days up to several months. In this paper we analyze a lightning storm that raged for seven and a half months at a planetocentric latitude of
Lightning and Thunderstorm Observations by Cassini and Voyager Spacecraft at Saturn
Indication for the existence of lightning in Saturn's atmosphere was first obtained in November 1980 by the radio instrument on-board Voyager 1 which recorded strong impulsive radio signals. The same
Possible Transient Luminous Events Observed in Jupiter's Upper Atmosphere
Eleven transient bright flashes were detected in Jupiter's atmosphere using the ultraviolet spectrograph instrument on the Juno spacecraft. These bright flashes are only observed in a single spin of
Peak electron densities in Saturn's ionosphere derived from the low‐frequency cutoff of Saturn lightning
Radio bursts from Saturn lightning have been observed by the Cassini Radio and Plasma Wave Science instrument at frequencies of a few megahertz during several month-long storms since 2004. As the
Atmospheric Electricity at the Ice Giants
Lightning was detected by Voyager 2 at Uranus and Neptune, and weaker electrical processes also occur throughout planetary atmospheres from galactic cosmic ray (GCR) ionisation. Lightning is an

Galileo Images of Lightning on Jupiter
In October and November of 1997 the Galileo Solid State Imager (SSI) detected lightning from 26 storms on the night side of Jupiter. More than half the surface area of the planet was surveyed. The

On the Intensity of Saturn Lightning
In the year 2004 the radio signatures of most SEDs (Saturn Electrostatic Discharges) were recorded when Cassini was at a distance of more than 80 Saturn radii away from the planet, and their
Optical efficiencies of lightning in planetary atmospheres
TLDR
These first simulations of lightning in planetary atmospheres by laser-induced plasmas show that the fraction of the energy in lightning discharge channels that is radiated in the visible spectrum is similar for Earth, Venus and Titan, but quite different for Jupiter.
