A view of a computer-generated model of the Earth's magnetosphere. Semi-transparent surfaces represent particle density (red is high, blue is low) and silvery tubes represent the magnetic field lines. In this particular model, the solar wind has an ambient density of 8.35 particles/cm^3. The isosurfaces are then red (> 17 particles/cm^3), yellow (> 12 particles/cm^3), green (> 8.6 particles/cm^3) and blue (< 1.0 particle/cm^3).
