What is "cosmochemistry"

n. (context chemistry English) the science that deals with the creation of the elements, and their isotopic distribution, in the universe; also with the synthesis and reactions of simple molecules in interstellar space

Cosmochemistry (from Greek κόσμος kósmos, "universe" and χημεία khemeía) or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions. This is done primarily through the study of the chemical composition of meteorites and other physical samples. Given that the asteroid parent bodies of meteorites were some of the first solid material to condense from the early solar nebula, cosmochemists are generally, but not exclusively, concerned with the objects contained within the Solar System.
