Abstract: The detection of cosmic neutrinos represents a crucial milestone in the advancement of multimessenger astronomy, a rapidly evolving field of research. Within this framework, the KM3NeT experiment plays a significant role, with the Istituto Nazionale di Fisica Nucleare (INFN) actively contributing to the construction of an underwater km3 neutrino telescope near Portopalo di Capo Passero (Sicily). Due to its strategic location in the Northern Hemisphere, KM3NeT provides complementary sky coverage to the IceCube detector at the South Pole, offering the observational advantage to observe the galactic plane and the galactic centre. Although still in a partial configuration, the telescope is already producing physics results, demonstrating its great potential in the field of neutrino astronomy. This seminar will provide an overview of the KM3NeT experiment, its technological advancements, and its scientific objectives. A particular focus will be given to the recent record-breaking neutrino detection, its implications for fundamental physics and astrophysics, and how KM3NeT contributes to the global effort in understanding the most energetic and elusive particles in the cosmos.
