The Sun’s Dynamic Loops
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.
