Original Caption Released with Image:

A small prominence slowly rose further up above the sun, then fell apart and back into the sun over about seven hours (Dec. 6, 2017). Prominences, notoriously unstable, are cooler clouds of particles tethered not far above the sun by magnetic forces. When it stretched out, its distance above the sun was several times the size of Earth. Images were taken in a wavelength of extreme ultraviolet light. These images are colorized since we cannot "see" ultraviolet light. In this case, a yellow tone was used instead of the normal red tint we use for this 304 Angstrom wavelength.


SDO is managed by NASA's Goddard Space Flight Center, Greenbelt, Maryland, for NASA's Science Mission Directorate, Washington. Its Atmosphere Imaging Assembly was built by the Lockheed Martin Solar Astrophysics Laboratory (LMSAL), Palo Alto, California.
