Astronomie - D.H.Menzel

Donald Howard Menzel (April 11, 1901 - December 14, 1976) was one of the first theoretical astronomers and astrophysicists in the United States. He discovered the physical properties of the solar chromosphere, the chemistry of stars, the atmosphere of Mars, and the nature of gaseous nebulae.[1][2] The minor planet 1967 Menzel was named in his honor,[3] as well as a small lunar crater located in the southeast of Mare Tranquilitatis, the Sea of Tranquility.[4] Astronomie - D.H.Menzel. .
