Original Caption Released with Image:

Three distinct active regions with towering arches above them rotated into view over a three-day period (Sept. 24-26, 2017). In extreme ultraviolet light, charged particles that are spinning along the ever-changing magnetic field lines above the active regions make the lines visible. To give some sense of scale, the largest arches rose up many times the size of Earth.


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.
