NASA released video on January 15 showing a set of ‘magnetic arches’ which were created in December 2015 when a dark solar filament above the sun’s surface became unstable and then erupted.
The video was captured by NASA’s Solar Dynamics Observatory (SDO) and then put onto social media.
NASA said on social media that a small eruption in the upper right part of the sun’s filament was most likely related to the collapse.
NASA also said that the ‘arches’ give the impression of a glow as they emit light in extreme ultraviolet wavelengths. This in turn highlights the charged particles spinning along the magnetic field lines of the sun.
NASA added that the video was taken in extreme ultraviolet wavelengths of 193 angstrom ( a unit of measurement equivalent to one ten-billionth of a metre), this type of light is usually invisible to the human eye, but was colored bronze in the video. (Reuters)
