190-sunspots – This high-resolution illustration provides a detailed view of an active sunspot group embedded within the solar photosphere. The painting accurately depicts the dark, cooler central region of the main sunspot known as the umbra, surrounded by the lighter, filamentary structure of the penumbra where magnetic field lines emerge more obliquely. The surrounding solar surface is rendered with a dense, mottled pattern representing the bubbling convection cells of solar granulation.
