The stunning series of magnetic arches was generated by solar filament eruption.

NASA’s Solar Dynamics Observatory captures a stunning video of swirling magnetic arches on the Sun which were generated by the eruption of dark solar filament. The eruption took place back in December last year but the video of the action was released by NASA recently.

“A dark solar filament above the sun’s surface became unstable and erupted on December. 16-17, 2015, generating a cascade of magnetic arches.” NASA explains in a statement.

“A small eruption to the upper right of the filament was likely related to its collapse. The arches of solar material appear to glow as they emit light in extreme ultraviolent wavelengths, highlighting the charged particles spinning along the sun’s magnetic field lines.”

Solar filaments are dark lines or curves that appear on the surface of the sun and can be easily spotted in the video. Solar filaments are actually the huge arcs of plasma or electrified gas and look dark as they are slightly cooler than the rest of the Sun's surface.

Filaments peak the most when sun’s magnetic field is very active and solar flares occur frequently. 

Solar filaments can collapse when the magnetic field of the area surrounding them becomes unstable. Then, these filaments erupt and cause explosions.  

The only reason why we are able to see these mesmerizing magnetic arches is because NASA’s scientists have colorized it to highlight its detail. Otherwise, they are invisible to human eyes.

“The video was taken in extreme ultraviolent wavelengths of 193 angstorms, a type of light that is typically invisible to our eyes, but is colorized here in bronze.”Space agency said.
