- Project Poltergeist in 1956 first detected neutrinos, postulated by Wolfgang Pauli in 1930 as nearly undetectable particles.
- Raymond Davis's experiment in the 1960s revealed the solar neutrino problem, finding fewer neutrinos from the sun than predicted.
- Kamiokande and Super-Kamiokande confirmed the shortfall and showed neutrinos oscillate between three flavors, implying they have mass.
- Modern detectors like IceCube and KM3NET map neutrinos from cosmic sources, including active galaxies and high-energy events.
- New facilities like JUNO, Hyper-K, and DUNE aim to further study neutrino oscillations with increased precision.
