KM3NeT is a research infrastructure housing the next generation neutrino telescopes. Once completed, the telescopes will have detector volumes between megaton and several cubic kilometres of clear sea water.

It hosts water Cherenkov neutrino telescopes designed to detect and study neutrinos from distant astrophysical sources as well as from our own atmosphere, contributing significantly to both astrophysics and particle physics knowledge. [1]

Feb 12, 2025 · The KM3NeT/ARCA (Astroparticle Research with Cosmics in the Abyss) detector is mainly dedicated to the study of the highest energy neutrinos and their sources in the Universe. It is located at 3450 m depth, about 80 km from the coast of Portopalo di Capo Passero, Sicily.

Feb 8, 2025 · Here we report an exceptionally high-energy event observed by KM3NeT, the deep-sea neutrino telescope in the Mediterranean Sea 4, which we associate with a cosmic neutrino detection. We detect...

Feb 12, 2025 · Astrophysicists have observed the most energetic neutrino ever. The particle — which probably came from a distant galaxy — was spotted by the Cubic Kilometre Neutrino Telescope (KM3NeT),...

The KM3NeT neutrino telescope, currently under construction, is a giant deep-sea infrastructure distributed across two detectors, ARCA and ORCA. In its final configuration, KM3NeT will occupy a volume of more than one cubic kilometer. KM3NeT uses sea water as the interaction medium for neutrinos. Its high-tech optical modules detect the ...

Feb 12, 2025 · The highest-energy cosmic neutrino detected to date was observed by KM3NeT, which sits at the bottom of the Mediterranean Sea near Sicily, Italy and Provence, France.

Feb 12, 2025 · The KM3NeT telescope located deep in the Mediterranean Sea is one such observatory, designed to catch high-energy neutrino events via these flashes of light. A record-breaking discovery On February 13, 2023, the KM3NeT team …

Feb 12, 2025 · The KM3NeT detectors. The KM3NeT/ARCA detector (Astroparticle Research with Cosmics in the Abyss) is primarily dedicated to studying the highest-energy neutrinos and their sources in the Universe. The detector is located at a depth of 3,450 m, about 80 km off the coast of Portopalo di Capo Passero, Sicily.

Feb 12, 2025 · The KM3NeT experiment comprises two detector arrays—ARCA, which lies off the coast of Italy at a depth of 3450 m, and ORCA, which lies off the coast of France at a depth of 2450 m. Each array consists of a collection of vertical detection lines that are anchored to the seafloor and spaced out in a grid pattern.
