About this work
Arches of magnetic field lines towered over the sun’s edge as a pair of active regions began to rotate into view in this video captured by NASA’s Solar Dynamics Observatory on April 5-6, 2016. Active regions are areas of very concentrated magnetic field. Charged particles spiraling along these magnetic fields emit extreme ultraviolet light, which is typically not visible to our eyes, but colorized here in gold.
