"Coronal loops are bundles of unresolved strands that are heated by storms of nanoflares."

Coronal heating is a dynamic process. The brightness of the observed X-ray and ultraviolet emission is strongly dependent on the density of the coronal plasma. Where there's low density, there isn't much brightness. Where there's high density, there's a lot of brightness. The corona is mostly bright at about 1 million degrees K. Coronal loops are the fundamental building blocks of the thin, translucent gas known as the sun's corona.
