Ultraviolet
Further information: Ultraviolet astronomyUltraviolet telescopes make observations at ultraviolet wavelengths, i.e. between approximately 10 and 320 nm. Light at these wavelengths is absorbed by the Earth's atmosphere, so observations at these wavelengths must be performed from the upper atmosphere or from space. Objects emitting ultraviolet radiation include the Sun, other stars and galaxies.

Famous quotes containing the word ultraviolet:
“As if the musicians did not so much play the little phrase as execute the rites required by it to appear, and they proceeded to the necessary incantations to obtain and prolong for a few instants the miracle of its evocation, Swann, who could no more see the phrase than if it belonged to an ultraviolet world ... Swann felt it as a presence, as a protective goddess and a confidante to his love, who to arrive to him ... had clothed the disguise of this sonorous appearance.”
—Marcel Proust (1871–1922)
“Like ultraviolet rays memory shows to each man in the book of life a script that invisibly and prophetically glosses the text.”
—Walter Benjamin (1892–1940)
