WebMar 6, 2024 · In astronomy, extinction is the absorption and scattering of electromagnetic radiation by dust and gas between an emitting astronomical object and the observer. Interstellar extinction was first documented as such in 1930 by Robert Julius Trumpler. [1] [2] However, its effects had been noted in 1847 by Friedrich Georg Wilhelm von Struve, … Als Extinktion (von lateinisch extinctio „Auslöschung“) bezeichnet man in der Astronomie die Schwächung des Lichts von Himmelskörpern beim Durchgang durch die Erdatmosphäre oder interstellare Materie. Unter dem Begriff Extinktion wird die Schwächung durch Absorption im durchquerten Medium sowie durch Streuung zusammengefasst, vgl. Extinktion (Optik). Diese Schwächung ist von der Wellenl…
