Spun and Confused

A long arch of plasma (called a prominence) was pulled this way and that by magnetic forces for a week before it finally dissipated (July 10-16, 2014). This close up was captured in extreme ultraviolet light. The Earth scale in the lower left corner gives one a sense of the length of the prominence. This one held itself together for quite a long time, as these things go. Credit: Solar Dynamics Observatory/NASA.
