KM3NeT collaboration is building two neutrino telescopes in the Mediterranean Sea. One is the ARCA detector, optimised for searches for high- energy neutrino sources in the Universe and it is under construction at the Capo Passero site, Italy, 80 km offshore at a depth of 3500 m; and the other is 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 the final configuration, ARCA will consist of 2 Building Blocks (BB), each one of 115 Detection Units (DU), with a total of more than 64000 optical sensor in a volume of about 1 km3 of water. In this contribution, the results of the KM3NeT/ARCA telescope obtained with data collected from May 2021 to December 2022 with evolving detector geometries and the perspectives for the KM3NeT/ARCA full telescope to detect the high energy neutrino sources in the Universe are presented.
