WebThe chromosphere is a thin layer of plasma that lies between the Sun’s visible surface (the photosphere) and the corona (the Sun’s upper atmosphere). It extends for at least 2,000 km (1,200 mi.) above the surface. The chromosphere is normally hidden from our view; its light is drowned out by the brilliance of the underlying photosphere. WebA plage / pleɪdʒ / is a bright region in the Sun 's chromosphere, typically found in and around active regions. Historically, they have been referred to as bright flocculi, in contrast to dark flocculi, and as chromospheric faculae, in contrast to photospheric faculae.
