What are these glorious golden space swirls? According to NASA, who captured this video with the Solar Dynamics Observatory (SDO), this happened when a dark solar filament erupted and caused a chain reaction.They call these cascading magnetic arches because what you see here is a lot of particles spinning around the sun's magnetic field lines.
Here's a video where you can see what a dark solar filament looks like. The darker area, almost in the shape of a circle is it. Filaments are plasma held above the sun's surface by magnetic forces.
