NASA's Solar Dynamics Observatory Captures Cascading Magnetic Arches

A dark solar filament above the sun's surface became unstable and erupted on December 16-17, 2015, generating a cascade of magnetic arches. The arches of solar material appear to glow as they emit light in extreme ultraviolet wavelengths, highlighting the charged particles spinning along the sun's magnetic field lines.
