Several active regions embedded in the Sun's surface began to rotate into view, showing off an array of loops and magnetic connections (July 31 - Aug. 1, 2013). Particles spinning along the magnetic field lines reveal the connecting loops and strands when viewed in extreme ultraviolet light. These active regions are areas of intense magnetic forces pulling against each other. The video covers about 12 hours of activity. Credit: Solar Dynamics Observatory/NASA.
