More Io Torus Images - click to enlarge

A cartoon of the Jupiter magnetosphere by John Spencer, Lowell Observatory.
The Io plasma torus during one rotation of Jupiter. The torus surrounds Jupiter near Io's orbit, and is tilted because of the tilt in Jupiter's magnetic field. 
And the required picture from the SL9 impacts. (more information in the full image.) 
The Io torus with a magnetic dipole field line drawn in. See how the "ribbon" is parallel to the field line, and also how the torus is offset to the left (dawn) side.

The torus images & animation above were made possible by grants from NASA's Planetary Astronomy division and the National Science Foundation's PYI program.
