The Foundations of Astrochemistry
The Origins of Astrochemistry
The study of astrochemistry, which involves the exploration of the chemical composition and processes of celestial objects, has its roots in the early 20th century. The field emerged as a result of the growing interest in the composition of the atmospheres of planets and the study of interstellar molecules.
One of the key figures in the development of astrochemistry was the American chemist, Harold Urey, who won the Nobel Prize in 1934 for his work on the separation of the elements in uranium. Urey and his colleagues used the newly developed method of gas chromatography to study the composition of the atmospheres of the giant planets in our solar system.
Another significant contribution to the field of astrochemistry was made by the Dutch astronomer, Jan Oort, who proposed the existence of a vast cloud of frozen hydrogen in the outer reaches of the Milky Way galaxy. This so-called “Oort cloud” is now believed to be the source of many long-period comets that enter the inner solar system.
The study of interstellar molecules also played a crucial role in the development of astrochemistry. In the 1960s, the radio astronomer, Fred Hoyle, and his colleagues discovered the first interstellar molecule, the carbon monoxide (CO) molecule, which was detected in the Milky Way galaxy. This discovery marked the beginning of a new era in the study of interstellar chemistry and led to the detection of many other molecules in the interstellar medium.
