Ultraviolet radiation

Electromagnetic radiation that has a shorter wavelength and higher energy than visible light.

Photosphere

The optical surface of the Sun. All of the Sun’s visible light that reaches Earth comes from here.

Faculae

Faculae are brighter, more prominent patches of the solar photosphere (the ‘surface’ of the Sun). They are sometimes an indication of a forming sunspot and show up particularly well through white-light solar filters.
