Jovian lightning was thought to originate in deep liquid water clouds but has been observed in high altitude shallow clouds filled with an ammonia-water solution by Juno’s star camera.
Jupiter’s magnetic field is changing in time and its atmospheric winds are likely responsible for this variation.
Juno discovered 8 cyclones positioned in the form of an octagon around the north pole and 5 forming a pentagon around the south pole.
Water and ammonia are not well mixed in Jupiter’s atmosphere even at depths below their condensation levels.
Jupiter’s magnetic field is more complex in the northern hemisphere and its North-South asymmetry is likely due to interior structure
Juno infrared observations of the Jovian aurora surprised scientists by showing mysterious new details related to Jupiter’s volcanic moon Io.
Jupiter produces lightning at multiple wavelengths, similar to the lightning we experience on Earth.
Unlike particles observed by Galileo Probe 20 years ago, Juno discovered a new radiation belt resting just above Jupiter’s atmosphere.
Scientists discovered that the depth of Jupiter’s atmospheric jet streams span far deeper than they imagined.
