KM3NeT is a neutrino telescope with two detectors - ARCA and ORCA - at the bottom of the Mediterranean Sea. It is also an international consortium of research institutes and university groups collaborating to operate the two detectors - www.km3net.orghttps://bsky.app/profile/km3net.bsky.socialhttps://bsky.app/profile/km3net.bsky.social/post/3mjzgzv5pqc2fWelcome, ORCA38! 🎉 After 4 days of flawless operations at sea, the ORCA detector just got a major upgrade: 5 new detection units installed in the deep sea, bringing the total to 38. A huge thank you to everyone involved, offshore crews and onshore teams, for making this great step forward possible!21 Apr 2026 16:53 +0000at://did:plc:3rgfmlz2a442je3a4kyoihxw/app.bsky.feed.post/3mjzgzv5pqc2fhttps://bsky.app/profile/km3net.bsky.social/post/3mjy5djhx3c2dToday on #worldcreativityandinnovationday2026 we celebrate our #innovative optical module, our #creative anchoring method in the deep Mediterranean Sea and the #beauty of neutrino detection with KM3NeT. 🎶Enjoy this piano recital by KM3NeT scientists. #km3net #neutrino21 Apr 2026 04:26 +0000at://did:plc:3rgfmlz2a442je3a4kyoihxw/app.bsky.feed.post/3mjy5djhx3c2dhttps://bsky.app/profile/km3net.bsky.social/post/3mjgx7yglg22iHappy World Quantum Day! Today, we dive into the fascinating world of neutrinos. At the ORCA detector of KM3NeT, deep beneath the Mediterranean Sea, we investigate the quantum phenomenon of neutrino oscillations, where neutrinos change flavor as they travel. #KM3NeT #neutrinos #WorldQuantumDay14 Apr 2026 08:22 +0000at://did:plc:3rgfmlz2a442je3a4kyoihxw/app.bsky.feed.post/3mjgx7yglg22ihttps://bsky.app/profile/km3net.bsky.social/post/3mj2tnrnnok2nKM3NeT proudly announces the first call for transnational access to KM3NeT data for external users!
