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.
