Stellar evolution and related nucleosynthesis play a fundamental role in the understanding of the origin of the chemical elements, the generation of energy, the luminosity of neutrinos and in many related astrophysical problems. The main goal of nuclear astrophysics is to provide a firm base for all these studies. Thousands of nuclear interactions, either strong or weak processes, are of astrophysical interest. For most of them, the knowledge of their cross sections (or reaction rates) at relatively low energy is required to understand the synthesis of the elements. The Laboratori Nazianali del Gran Sasso (INFN) has been for a long time a unique infrastructure hosting an accelerator devoted to Nuclear Astrophysics, the Laboratory for Underground Nuclear Astrophysics (LUNA). The LUNA Collaboration has shown that, by going underground and by using the typical techniques of low background physics, it is possible to measure nuclear cross sections down to the energy of the nucleosynthesis inside stars. I will give an overview of the experimental techniques adopted in underground nuclear astrophysics and will present a summary of the LUNA main recent results and achievements.
