The picture shows swirling cloud belts and turbulent eddies in the northern hemisphere of Jupiter. On May 23, 2018, the spacecraft Juno produced this frame during the period of the 13th passing span. At that time, the distance was 15,500 km from cloudy peaks at 56 degrees north latitude.
The region observed here is chaotic and turbulent. Dark material reflects the clouds deep in the atmosphere, and light - at high altitude. Bright areas are ammonia and water mixed with unknown chemical constituents.
In the center stands a bright oval. This formation appears uniformly white in ground-based observations. But JunoCam displays a small-scale structure inside the weather system, including additional formations inside it. There is no noticeable movement. It seems that the winds are significantly slowing towards the center.
