KM3NeT is a neutrino telescope consisting of strings of optical detectors placed deep beneath the ocean. Credit: KM3NeT On Feb. 13, 2023, something extraordinary happened deep beneath the Mediterranean Sea. KM3NeT’s Astroparticle Research with Cosmics in the Abyss (ARCA) telescope, a sprawling underwater array of ultra-sensitive photodetectors, caught sight of the telltale sign of an … Read more
When it comes to particles, only photons are more abundant than neutrinos, yet detecting neutrinos is extremely difficult. Scientists have gone to extreme lengths to detect them, including building neutrino observatories in deep, underground mines and in the deep, clear ice of Antarctica. One of their latest efforts to detect neutrinos is KM3NeT, which is … Read more
Recent research on lightweight particles called neutrinos might have passed you by – much like the more than 10 trillion neutrinos passing through your body each second. Now, our new paper – with 21 countries, more than 60 institutes and around 360 scientists contributing – reports the observation of the most energetic neutrino yet. Despite … Read more
This is the optical module of the telescope KM3NeT that has captured the highest energy neutrino yet known. It made the discovery from the dark depths of the bottom of the Mediterranean Sea.
