Magnetic Activity
These two images are of the same spot on the Sun and were taken on March 17 using the Extreme Ultraviolet Imager and the Polarimetric and Helioseismic Imager, which is made up of two telescopes that survey the Sun’s magnetic field. The Extreme Ultraviolet Imager took the yellow image (color was added afterwards), which shows the loops of magnetism reaching into the stellar atmosphere, capturing hot gas along the way. The black-and-white image comes from the Polarimetric and Helioseismic Imager, where the two colors represent different zones of polarity.
