That’s a storm, by Jove!

A Jovian storm, captured by JunoCam.

NASA’s JunoCam captured this image a month ago as the Juno spacecraft skirted the upper rim of Jupiter’s atmosphere, hovering above the
giant planet’s cloud tops at an altitude of approximately 14,500 kilometres.

The shot captures a massive turbulent storm, with spiralling streams of cloud emanating
from a central oval-shaped cloud structure that rotates within the Jovian
southern hemisphere.

The raw image was tweaked for clarity by a citizen scientist
called Roman Tkachenko.
