This projection of the radial magnetic field of Jupiter (top) uses a new magnetic field model based on data from Juno's orbits during its prime mission. Magnetic field lines emerge from yellow and red regions and enter the planet in the blue regions. The new model represents a vast improvement in spatial resolution compared to prior knowledge (bottom) provided by earlier missions, including Pioneer 10 and 11, Voyager 1 and 2, Ulysses, and Galileo.
