The Juno probe (JUpiter Near-polar Orbiter) will leave its orbit around Jupiter after the end of the mission in July 2021 and will crash/burn in the Jupiter atmosphere. For the first time it will go into the inner area of the moons of Jupiter, which it has previously avoided because of the high radiation levels there.
The image also includes (with a certain level of artistic freedom) the Galilean moons (from left to right: Ganymed, Io, Callisto, Europa) and the very thin ring system around the planet.
