The Sun’s Dynamic Loops

The Sun's dynamic loops.
NASA
Giant loops of plasma above the SunÕs surface are swaying back and forth, spanning distances up to an estimated 100,000 miles (September 18-19, 2013).
The video clip covers a little over a day of activity viewed in extreme ultraviolet light. The loops actually are charged particles spiraling along numerous groups of magnetic field lines extending above active regions.
Meanwhile, a darker, cooler mass of plasma swirled and twisted above the Sun in the upper left area of the frames.
