Neutrinos are extremely difficult to detect. However, in recent years large detectors located in deep laboratories to avoid cosmic background radiation have helped to define the properties of neutrinos and their role in the most basic laws of physics. Neutrinos have also become a valuable cosmic messenger, providing unique information from the core of the Sun and from the deepest reaches of the Universe. The lecture will discuss the current status of neutrino experiments, the role of neutrinos in basic physics and astrophysics and future measurements made possible by the low radioactivity experimental environment.
