On July 5, 2017, NASA’s Solar Dynamics Observatory watched an active region — an area of intense and complex magnetic fields — rotate into view on the Sun. This image shows a blended view of the sunspot in visible and extreme ultraviolet light, revealing bright coils arcing over the active region — particles spiraling along magnetic field lines. via NASA ift.tt/2v43I2x
