This image from NASA’s Solar Dynamics Observatory (SDO) shows a very long, whip-like solar filament extending over half a million miles in a long arc above the sun’s surface. Filaments are cooler clouds of solar material that are tethered above the sun’s surface by unstable magnetic forces. The image and video, which covers August 6 to 8, show the filament as a darker strand that has been in view for several days. Towards the end of the video part of the filament seems to break away, but its basic length and shape seem to have remained mostly intact.
NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.
