Falanqaynta ugu horreysa ee ultraviolet-ka waxaa la sameeyay 1920-yadii, markii Frank E. Ross uu ogaaday in sawirrada ultraviolet-ka ay muujiyeen faahfaahin aad u badan oo ka maqan iftiinka muuqda iyo infrared. Wuxuu soo jeediyay in tani ay sabab u tahay jawiga jaalaha ah, jaalaha ah ee hoose oo leh daruuro sare oo cirrus ah oo ka sarreeya. Falanqaynta spectroscopic ee 1900s waxay siisay tilmaamaha ugu horreeya ee ku saabsan wareegga Venus. Vesto Slipher wuxuu isku dayay inuu ka saaro Doppler Doppler ee Venus, laakiin ma uusan ogaan karin wax wareejin ah.
