JUNO Observatory publishes first results on neutrino physics mystery
The Jiangmen Underground Neutrino Observatory (JUNO) collaboration in China has published its first results, based on 59 days of data collected in late 2025. The observatory calculated how often particles called neutrinos from nuclear reactors change their flavour or type as they travel. These findings confirm that JUNO is functioning as expected and is on track to help solve the complex question of neutrino mass ordering, which involves determining the heaviest and lightest neutrino flavours.
Key Points
- JUNO collaboration in China published its first results on neutrino physics.
