The Sun as seen by the ESA/NASA Solar Orbiter spacecraft on 25 March 2022, one day before its closest approach of about 0.32 au, which brought it inside the orbit of planet Mercury. The central image was taken by the Extreme Ultraviolet Imager (EUI) instrument. The outer image was taken by the coronagraph Metis, an instrument that blocks out the bright light of the Sun’s surface in order to see the Sun’s faint outer atmosphere, known as the corona. The Metis image has been processed to bring out structures in the corona. This revealed the switchback (the prominent white/light blue feature at the roughly 8 o’clock position in the lower left). It appears to trace back to the active region on the surface of the Sun, where loops of magnetism have broken through the Sun’s surface.
