The Juno science team today released the mission’s first science results gathered during its first close fly-by of Jupiter.
I have cropped on the right one of their full images to focus in on two of the strangely shaped storms Juno imaged during its pass. This image is of the northern pole. They also have some fascinating images of the south pole storms as well. Unlike the equatorial regions, which on gas giants have what appear to be parallel coherent bands of weather, the poles appear very chaotic, with the storms forming shapes that have not been seen in any other atmosphere in the solar system. They also found a hexagon-shaped weather feature in the pole.
The first link above also included data from the spacecraft’s other instruments, showing the gas giant’s complex atmosphere in a variety of other wavelengths.
