NASA's Juno mission to Jupiter reveals a planet with an interior structure that is much more complex than ever previously thought. At least that’s the latest word from several of Juno’s scientific team members who were on hand at a press conference at the European Geosciences Union’s 2026 General Assembly last week in Vienna. Now on its 83rd orbit around the giant planet and its many moons, the Juno team described the solar-powered spacecraft’s health as excellent. Launched in 2011, Juno arrived at Jupiter in 2016 with science goals intended to shed light on the planet’s formation and evolution. The idea was to measure the gas giant’s interior, its atmosphere, its polar magnetosphere, as well as both its magnetic field and gravity field. And to those ends, it has made great progress. At present, Juno is making its way towards Jupiter’s North Pole in a region that’s hardly been explored due to the gas giant’s powerful radiation belts.…
