English: Original caption:

Jupiter is shown with several important components of its magnetosphere in this artist's representation. The planet's magnetic field is represented by soft purple lines that connect its north and south magnetic poles. Jupiter's brilliant auroras glow at the poles, while the bright areas to the left and right of the planet's equator represent the regions of most intense charged particle radiation - Jupiter's inner radiation belts. The Juno spacecraft will, broadly speaking, pass between the planet and the most intense areas of radiation.

This view visualizes only the inner part of the magnetosphere. The complete Jovian magnetosphere is an enormous, tadpole-shaped structure that balloons out to dozens of Jupiter widths around the planet. In the direction away from the sun, the magnetotail extends as far as the orbit of Saturn.
