Our planet lies within an active and dynamic interplanetary space environment resulting from the expansion of our Sun's atmosphere, the solar corona, expanding outwards through the inner heliosphere at supersonic speeds. This carries with it vast amounts of plasma along with an embedded interplanetary magnetic field (IMF). This variable, but continuous, outflow is known as the solar wind, but it also includes large structures such as coronal mass ejections (CMEs). CMEs are eruptions of dense, highly-magnetised plasma, launched at high speeds from the Sun out into the heliosphere. These ever-changing conditions drive processes in the Earth's space-environment (the mag-netosphere and ionosphere), as well as at other planetary bodies in the solar system, which can strongly affect satellite/spacecraft communications, Earth's navigation systems and power grids, and other complex technologies and infrastructures upon which modern society relies. Collectively, study of the Sun-Earth-Heliosphere system is known as heliophysics.
