Mix master: Modeling magnetic reconnection in partially ionized plasma

Many of the most dramatic events in the solar system — the spectacle of the Northern Lights, the explosiveness of solar flares, and the destructive impact of geomagnetic storms that can disrupt communication and electrical grids on Earth — are driven in part by a common phenomenon: fast magnetic reconnection. In this process the magnetic field lines in plasma — the gas-like state of matter consisting of free electrons and atomic nuclei, or ions — tear, come back together and release large amounts of energy.
