The KM3NeT underwater neutrino telescope: status and future perspective

The KM3NeT collaboration started to build a multi-km3 neutrino telescope in the Mediterranean Sea. The telescope is composed of the ARCA detector, optimised for searches for high-energy neutrino sources in the Universe under construction at the Capo Passero site, Italy, 80 km offshore at a depth of 3500 m; and the ORCA detector, near Toulon, France, 40 km offshore at a depth of 2500 m, aimed at the determination of the mass hierarchy of neutrinos. In this contribution, an overview of the latest results and the future perspectives for the KM3NeT telescopes to detect the high energy neutrino sources in the Universe with the ARCA telescope and to determine the properties of the elusive neutrino particles with ORCA detector are presented.
