Observation of an ultra-high-energy cosmic neutrino with KM3NeT
On February 12, 2025, The KM3NeT Collaboration has announced the detection from the abyss of the Mediterranean Sea of a cosmic neutrino with a record-breaking energy of about 220 PeV.

Tau neutrinos and neutrino mixing with ORCA6
6 February 2025 – We present a new paper with the title ‘A study of tau neutrinos and non-unitary neutrino mixing with the first six detection units of KM3NeT/ORCA‘.
A fruitful Collaboration Meeting in Louvain-la-Neuve!
4 February 2025 – Last week, KM3NeT has met, both in person and online, for its winter Collaboration Meeting , in Louvain-la-Neuve, Belgium, hosted by UCLouvain.
Sneak peek into the KM3NeT labs: Nikhef
17 January 2025 – Today we start a series of items highlighting the work of our technical staff in the labs of KM3NeT. Numerous technicians and engineers are working on the construction of the ARCA and ORCA detectors of the KM3NeT neutrino telescope. Together, but in distributed labs, they design and build the many detector components, assemble them into thousands of optical modules and integrate them into hundreds of deployment-ready detection units. It requires high standards of quality control and logistics between the labs.
Update of gSeaGen simulation software
23 November 2024 – In a new paper with the title ‘gSeaGen code by KM3NeT: an efficient tool to propagate muons simulated with CORSIKA’ we describe an open source solution for efficient simulation of cosmic-ray induced muons in neutrino telescopes.
Astronomy potential of ARCA
22 November 2024 – In a paper with the title ‘Astronomy potential of KM3NeT/ARCA’ we present improvements that indeed enhance the astronomy potential of the ARCA detector.
First searches for Dark Matter
20 November 2024 – In a new paper with the title ‘First searches for Dark Matter with the KM3NeT Neutrino Telescopes’ we present limits for neutrino production by Dark Matter annihilation in the Sun and the Galactic Centre. For the analysis we used the data of early configurations of the ARCA and ORCA detectors of KM3NeT.
KM3NeT gathered online for its fall collaboration meeting
13 November 2024 – Last week , the KM3NeT Collaboration has met online for its fall meeting.
Neutrino oscillations with ORCA6
29 October 2024 – Measurement of neutrino oscillation parameters with the first six detection units of KM3NeT/ORCA
In a new paper we show the potential of the ORCA detector: the measurements of neutrino oscillation parameters – with only 5% of ORCA’s final volume and during limited observation time – align with those from other experiments and are already becoming competitive.
