The Reach of a Solar Flare
Images and data from March 25 show us just how far a solar flare extends. The yellow images of the Sun were taken by the Extreme Ultraviolet Imager, showing a solar flare on the lower left side of the star. Zooming out shows data taken by Metis, which is a coronagraph, or an instrument that can image the Sun’s outer atmosphere. You can see how the solar flare excites a region of the atmosphere in the bottom left of the video. Zooming out even more, data from the Solar Orbiter Heliospheric Imager shows the mammoth scale of the coronal mass ejection as it shoots into space.
