A terrific composite of all the colors emitted by the sun from the National Optical Astronomy Observatory. Each of the fifty rows covers sixty angstroms (i.e. 0.1 nanometers) of the visible spectrum (which itself spans roughly 4000–7000 angstroms, or 400–700 nanometers), increasing in wavelength from left-to-right, bottom-to-top.
