Role of Low-Temperature Chemistry of Carbon in our Astrochemical History
The chemistry that takes place between stars determines the molecular composition of the solids from which all solid objects in new planetary systems are formed. A large fraction of this material survives during the star formation process maintaining its chemical composition. It is expected to be delivered to planets at their earlier stages.
Laboratory studies of the formation of carbonaceous solids under conditions similar to those of the interstellar medium have proved their predominantly organic nature. Therefore, the massive delivery of such organics to Earth and exoplanets should have a significant impact on the chemistry occurring on their surfaces and may also trigger the emergence of life. Recent discoveries of the presence of peptides in
meteorites and the way how these molecules may be formed in the interstellar medium give strong support to the hypothesis of molecular panspermia.
