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 the spacecraft and their brightness decays exponentially with time, with a duration of ∼1.4 ms. The spectra are dominated by H2 Lyman band emission and based on the level of atmospheric absorption, we estimate a source altitude of 260 km above the 1‐bar level. Based on these characteristics, we…

Detection of a Bolide in Jupiter's Atmosphere With Juno UVS
The Ultraviolet Spectrograph (UVS) instrument on the Juno mission recorded transient bright emission from a point source in Jupiter's atmosphere. The spectrum shows that the emission is consistent
A Comprehensive Set of Juno In Situ and Remote Sensing Observations of the Ganymede Auroral Footprint
Jupiter's satellite auroral footprints are a manifestation of the satellite‐magnetosphere interaction of the Galilean moons. Juno's polar elliptical orbit enables crossing the magnetic flux tubes

Study of Chemical Processes Initiated by Electrical Discharge in Titan-Related Atmosphere at Laboratory Temperature and Pressure
The chemical processes initiated by electrical discharges in prebiotic atmospheres became a hot topic during the past decade due to the recent extensive discovery of exoplanets. The biggest atmosph...
Transport Characteristics of the Electrification and Lightning of the Gas Mixture Representing the Atmospheres of the Solar System Planets
Electrification represents a fundamental process in planetary atmospheres, widespread in the Solar System. The atmospheres of the terrestrial planets (Venus, Earth, and Mars) range from thin to thick


Lightning on Jupiter observed in the Hα line by the Cassini imaging science subsystem
Prevalent lightning sferics at 600 megahertz near Jupiter’s poles
Observations of broadband emission from lightning on Jupiter at 600 megahertz show a lightning discharge mechanism similar to that of terrestrial lightning and indicate increased moist convection near Jupiter’s poles.
Measurements of radio frequency signals from lightning in Jupiter's atmosphere
During the descent of the Galileo probe through Jupiter's atmosphere, the lightning and radio emissions detector (LRD) instrument measured radio frequency signals presumably from electrical
Juno‐UVS approach observations of Jupiter's auroras
Comparing synoptic Juno‐UVS observations of Jupiter's auroral emissions, acquired during 3–29 June 2016, with in situ solar wind observations, and related Jupiter observations from Earth is compared.
Observation of moist convection in Jupiter's atmosphere
It is concluded that moist convection—similar to large clusters of thunderstorm cells on the Earth—is a dominant factor in converting heat flow into kinetic energy in the jovian atmosphere.
Discovery of rapid whistlers close to Jupiter implying lightning rates similar to those on Earth
Electrical currents in atmospheric lightning strokes generate impulsive radio waves in a broad range of frequencies, called atmospherics. These waves can be modified by their passage through the
Detection of visible lightning on Saturn
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,
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
A study of the possibility of sprites in the atmospheres of other planets
[1] Sprites are a spectacular type of transient luminous events which occur above thunderstorms immediately after lightning. They have shapes of giant jellyfish, carrots, or columns and last tens of
Morphology of the UV aurorae Jupiter during Juno's first perijove observations
On 27 August 2016, the NASA Juno spacecraft performed its first close‐up observations of Jupiter during its perijove. Here we present the UV images and color ratio maps from the Juno‐UVS UV imaging
