Cascading Magnetic Arches

This time lapse video was taken by the Solar Dynamics Observatory using UV light and shows a dark solar filament above the Sun’s surface that became unstable and erupted, generating a cascade of magnetic arches. A small eruption to the upper right of the filament may have been related to its collapse. The arches of solar material glow as they emit light in extreme ultraviolet wavelengths, highlighting the charged particles spinning along the Sun’s magnetic field lines.
