As the arcing loops above an active region began to rotate into a nice profile view, Solar Dynamic Observatory (SDO) captured the dynamic, magnetic struggles taking place below (July 6-8, 2010). Particles spiraling along magnetic field lines trace their paths. Magnetic forces in the active region are connecting, breaking apart, and reconnecting. These images were taken in extreme ultraviolet light. Although mostly hidden from our view, the active region did unleash a number of small flares. Credit: NASA/Goddard/SDO
