Neutron reactions in stellar enviroments, either quiescent or explosive, are responsible for the synthesis of elements heavier than iron. In this way the isotopic composition of stars comes to reflect the local evolution of the Universe. Recent advances in astronomy have made possible to analyze the abundances of elements present in very old stars. With the aid of an improved knowledge of neutron reactions this information can be transformed into a closer picture of the history of our Universe. This ideas will be underlined and the status and perspectives in the field will be highlighted.
