NASA Sees Sun's Curly-Q Filament Blast (IMAGE) NASA/Goddard Space Flight Center Caption A solar filament erupted in the shape of a twisted arch over a three-hour period (Feb. 4, 2015) with most of it falling back into the sun. The activity in the lower corona was caught in a wavelength of extreme ultraviolet light. Filaments are elongated clouds of particles suspended above the sun's surface by magnetic forces. They are notoriously unstable.
