NASA's Solar Dynamics Observatory has captured amazing activity on the sun -- what they're calling a solar eruption.
It happened back in December when a dark solar filament -- one of the dark lines or curves we see above the sun's surface -- became unstable.
The eruption caused a cascade of magnetic solar arches.
You can see the movement in the upper right of the video.
The images were taken in extreme ultraviolet wavelengths -- a type of light that is usually invisible to our eyes, but is colorized in the video in bronze.
