The image reveals striking details of the sunspot’s structure as seen at the sun’s surface. The sunspot is sculpted by a convergence of intense magnetic fields and hot gas boiling up from below.
This image uses a warm palette of red and orange, but the context viewer took this sunspot image at the wavelength of 530 nanometers — in the greenish-yellow part of the visible spectrum. This is not the same naked eye sunspot group visible on the sun in late November and early December 2020.
