Astrochemistry is the study of molecules in space, their formation, destruction pathways and efficiencies depend on the local environment. It is an overlap of astronomy and chemistry. The word "Astrochemistry" is applied to both the Solar System and the interstellar medium. The strong supporting evidence for abiogenetic theories of life: specifically, which hold that the essential molecular components of life came from extraterrestrial sources. Astrochemistry is closely linked with physics, specifically astrophysics. And there are more and more organic molecules in open space discovered, so that astro-biological aspects in this theme area find their way-not least with the question of the origin of life and for the existence of extraterrestrial life forms. Astrochemistry focuses at researching chemical methods in astronomical environments. This discipline-located at the crossroad between astrophysics and chemistry-is rapidly evolving and explores the issue of the formation of molecules of increasing complexity in particular physical conditions that deviate significantly from those frequently encountered in chemistry laboratories. The main goal of this paper is to provide an overview of this discipline. So far, about 170 molecules have been identified in the interstellar medium (ISM). The presence of this molecular diversity constitutes a firm evidence that efficient formation processes are at work in the interstellar medium.
