The Magnetosphere: Earth Raises its Shields

Visualizations by Tom Bridgman Released on February 28, 2002

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).

A profile view of the magnetosphere. The Sun would be located to the left. Lines from the Earth's magnetic field are stretched out behind the Earth to form the magnetotail.

A view of the magnetosphere on the sunward side. The interaction of the solar wind with the field and particles compresses this region to form a shield-like structure.

A closer view of the Earth inside the magnetosphere. The field lines do not reach the Earth due to the boundary of the computational model.
