Juno discovers “Great Blue Spot,” bands that may reflect deep zonal winds and other complex findings.
Juno discovers that Jupiter’s core is large, fuzzy and dilute. A surprise that has implications on how Jupiter formed and evolved.
Ganymede’s dark side, illuminated by Jupiter shine, reveals grooved terrain, small craters and puzzling ejecta deposits plus a possible scar from a comet, ejecta from a very distant crater.
Energetic particle measurements reveal new insights into Ganymede’s magnetosphere for the only close Juno flyby.
Plasma wave frequencies tell us about the number of electrons per unit volume in Ganymede’s magnetosphere.
The implication that Jupiter was acquiring other elements in addition to Hydrogen and Helium has important implications for the formation of giant planets in our solar system and beyond.
JunoCam acquired four color images of Ganymede at 1-4 km/pixel during PJ34 encounter, at higher spatial resolution than previously imaged (Voyager 1 -1979).
The Great Blue Spot (a localized patch of intense magnetic field on the equator near 80º west longitude) appears torn east and west by the action of deep zonal winds.
Characterizing the planetary magnetic field of Jupiter is one of the primary science objectives of the Juno Mission.
Juno UVS observed a bright flash of light in Jupiter’s upper atmosphere in April 2020.
