Ultraviolet astronomy is a term used in relation to observations of the electromagnetic radiation of the Universe in the ultraviolet range ( wavelengths from about 10 to 320 nanometers ). Shorter-wave (high-energy) photons are studied by X-ray astronomy and gamma-ray astronomy [1] . Light having these wavelengths is absorbed by the Earthβs atmosphere , so observation should be from upper layers of the atmosphere or from space [1] .
Measurement of the spectral lines of the ultraviolet range is used to determine the chemical composition, density and temperature of the interstellar medium , as well as the temperature and composition of young hot stars. Observations in the ultraviolet range provide significant information on the evolution of galaxies .
The main ultraviolet observing space telescopes are the Hubble Space Telescope and the Far Ultraviolet Spectroscopic Explorer (FUSE), although other instruments are used.
