78,846 Photos of the Sun Are Stitched Together into a Mesmerizing Timelapse of Its Movements

Using data from NASA’s Solar Dynamics Observatory, filmmaker Seán Doran composed an entrancing timelpase of the sun’s glowing coronal loops during a month-long period. The video project compiles 78,846 ångström-171 photographs from August 2014 that show the bright, curved structures, which are made of hot plasma, as they burst upward. Colorized in gold in the timelapse, the arced loops often form a bridge between dark sunspots, or places where powerful magnetic fields breach the surface and flow into the massive star’s atmosphere.
