Flickering Coronal Loops (VIDEO)

NASA/Goddard Space Flight Center

Caption

The four panels in this movie show brightness changes in coronal loops in four different wavelengths of extreme ultraviolet light (131, 171, 193, and 304 angstroms) before a solar flare in December 2011. The images were taken by the Atmospheric Imaging Assembly (AIA) on NASA’s Solar Dynamics Observatory and processed to reveal flickering in the coronal loops.
