(UV, ultraviolet light)
(electromagnetic radiation, wavelength 10-400 nm)

Ultraviolet (UV) is electromagnetic radiation (EMR) with wavelengths in the range of 10 nm to 400 nm, situated between visible light and X-ray radiation. Terms for subranges:

Terms used for sunscreen/sunblock:

Ultraviolet is a factor in a planet's habitability and the chances of life. Some UV is considered helpful in creating some of the molecules associated with Earth light, but too much UV breaks down vital molecules, and factors include the presence of a UV-protective atmosphere on extra-solar planets as well as the number and strength of the host star's stellar flares that include UV.
