Revealed in extreme ultraviolet light, our sun’s looping magnetic field lines are visible (watch in HD!) in this video from NASA’s Solar Dynamics Observatory (SDO) satellite. The action spans a two-day period from June 6 – 7, 2010, and features two particularly magnetically-active regions on the sun’s surface. Superheated solar material is caught up in the magnetic field and illuminates the lines as shifting arcs tens and hundreds of thousands of miles long. Some of the material extends even farther out into the sun’s atmosphere, joining the more diffuse magnetic lines of the corona.
