Buoyancy 1 (IMAGE) Rice University Caption An image from a magnetohydrodynamic simulation by the Gamera project at the Johns Hopkins Applied Physics Laboratory shows bursty flows (in red and brown) in the plasma sheet. Rice University space plasma physicists developed algorithms to measure the buoyancy waves that appear in thin filaments of magnetic flux on Earth's nightside. Credit K.
