Juno Reveals the Surprisingly Variable Jovian Ionosphere
Juno Waves measures ionospheric densities that are highly variable in space and time and likely driven by Jupiter’s anomalous magnetic field.

Juno sees the first Energetic Neutral Atoms (ENAs) from Io’s atmosphere
Juno sees the first Energetic Neutral Atoms from Io’s atmosphere suggesting that at night, its upper atmosphere may be a factor of 2 weaker than models suggest.

Juno Measures Oxygen Production at Europa
Juno directly measured the oxygen production at Europa and some of this oxygen could work its way into Europa’s subsurface ocean as possible source of metabolic energy.

Juno measures 3-dimensional high energy electron radiation surrounding Jupiter
The unique polar orbit of Juno has allowed the ASC star camera, a component of Juno’s Magnetosphere Investigation, to map out Jupiter’s ultra-high energy relativistic electron radiation.

Juno UV auroral imaging combined with Juno’s particle measurements are showing that Ganymede’s O2 atmosphere is an order of magnitude more copious than expected
Ganymede’s magnetosphere generates its own aurora, and observations by Juno of both the aurora and charged particles near Ganymede indicate a much greater amount of Oxygen molecules (O2) are present in the atmosphere than models suggest.

Juno Reveals Extraordinary Details on Ganymede’s Surface
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.
