Cosmochemistry is concerned with the origin and development of the elementss and their isotopes in the universe. It is connected to astrophysics, in particular to the physics of stars and supernovas. In particular, cosmochemsisty is also concerned with origin and the development of elements and their isotopes in our solar system and therefore cosmochemistry is also important in planetology and for the investigation of origin and development of our solar system. Many contributions to cosmochemistry are from the research of meteorites, because meteorites are, together with samples from moon, currrently the only extraterrestrial samples available for investigation in terrestrial laboratories.
