In the 1930s, major astronomical discoveries included the discovery of Pluto in 1930, the identification of the first Quasar in 1932, and the discovery of the first interstellar molecules in space in 1935. Additionally, the concept of an expanding universe was also proposed during this decade.
Modern examples: discovery of noble gases chemistry, VSEPR theory, discovery of fullerenes, organic electrical conductors, liquid crystals, nucleic acids structure, insulin synthesis, etc.
