Area of turbulence in the Northern magnetic cusp

Magnetic turbulence are mainly created where the solar wind - a constant flow of charged pareticles generated by the Sun - can directly access the magnetosphere, the natural magnetic shield that surrounds and protects our planet. Cluster is studying these phenomena in 3D.
