A magnetohydrodynamic simulation by the Gamera project at the Johns Hopkins Applied Physics Laboratory shows bursty bulk flows (in red and brown) in the plasma sheet approaching Earth on the nightside. Rice University space plasma physicists have developed algorithms to measure the buoyancy waves that appear in thin filaments of magnetic flux on the nightside. (Credit: Gamera/APL)
