Caption: Grainy sun: the images show the so-called granulation in four different wavelengths in near ultraviolet light. The image section depicts 1/20,000 of the entire surface. The smallest recognisable structures have an angular resolution equal to that of looking at a coin from a distance of 100 kilometres. The light structures are the foundational elements of the magnetic fields.
