Towering Coils


This video clip covers about 36 hours of Solar activity as seen by the Solar Dynamics Observatory in January, 2014.  A large active region sported tall coils of magnetic field lines that stretched many times the size of Earth above the Sun. When viewed in extreme ultraviolet light, the field lines are revealed as particles move along them. Some lines connect with another active region that has rotated out of view. This close-up also shows darker, cooler plasma just above the surface being tugged back and forth by magnetic forces.
