IceCube Neutrino Observatory
Cubic-kilometer neutrino detector embedded in Antarctic ice.
Overview
IceCube instruments a cubic kilometre of Antarctic ice with photomultiplier tubes that register light from neutrino interactions. It established high-energy astrophysical neutrinos as a new astronomical messenger.
Key discoveries
- Detection of a diffuse astrophysical neutrino flux
- Neutrinos traced to the blazar TXS 0506+056
- Foundation of neutrino multimessenger astronomy
