http://www.everything3d2.com/ NASAâ€™s Solar Dynamics Observatory (SDO) captures a very long, whip-like solar filament extending over half a million miles in a long arc above the sunâ€™s surface. Filaments are cooler clouds of solar material that are tethered above the sunâ€™s surface by unstable magnetic forces.
