Overview
Advanced view of Solar Flares & Coronal Mass Ejections
Solar flares and coronal mass ejections are major releases of energy from magnetically active regions on the Sun. A flare is a rapid burst of electromagnetic radiation and energetic particles, while a coronal mass ejection, or CME, is a large expulsion of magnetized plasma from the solar corona into interplanetary space.
Monitoring flares and CMEs helps forecast radiation hazards, satellite anomalies, radio disruptions, auroral activity, and geomagnetic storms. Their study also provides a nearby laboratory for magnetic reconnection, a process important throughout astrophysics.
