Astrochemistry is the study of the abundance and reactions of molecules in the universe, and their interaction with radiation. [1] The discipline is an overlap of astronomy and chemistry . The word "astrochemistry" may be applied to both the Solar System and the interstellar medium .
William Morgan Jackson (born September 24, 1936) is a Distinguished Research and Emeritus Professor of Chemistry at University of California, Davis and pioneer in the field of astrochemistry. His work considers cometary astrochemistry and the development of laser photochemistry to understand planetary atmospheres.
The discipline of astrochemistry includes understanding how these molecules form and explaining their abundances. The extremely low density of the interstellar medium is not conducive to the formation of molecules, making conventional gas-phase reactions between neutral species (atoms or molecules) inefficient.
Meteorites are often studied as part of cosmochemistry. Cosmochemistry (from Ancient Greek κόσμος (kósmos) 'universe' and χημεία (khēmeía) 'chemistry') or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions. [1]
