Scientists map the remaining mysteries of magnetic reconnection in space plasma
Researchers have identified key unsolved questions about magnetic reconnection—a violent plasma phenomenon that powers solar flares and geomagnetic storms—and outlined a research roadmap to answer them. Understanding this process better could improve forecasting of space weather events that disrupt satellites, power grids, and communications networks worth billions annually.
Originaltitel: Outstanding Questions and Future Research on Magnetic Reconnection
<p>This short article highlights unsolved problems of magnetic reconnection in collisionless plasma. Advanced in-situ plasma measurements and simulations have enabled scientists to gain a novel understanding of magnetic reconnection. Nevertheless, outstanding questions remain concerning the complex dynamics and structures in the diffusion region, cross-scale and regional couplings, the onset of magnetic reconnection, and the details of particle energization. We discuss future directions for magnetic reconnection research, including new observations, new simulations, and interdisciplinary approaches.</p>
