text: To get a little technical, ultraviolet (UV) means “beyond violet” and refers to a range of electromagnetic waves with a shorter wavelength (higher frequency and energy) than the visible violet light.
text: Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma ray astronomy.
