How To Identify Black Holes By Catching Neutrinos

Sep 14, 2026 · 24m

Summary

PBS Space Time explores the IceCube collaboration's detection of neutrinos from the active galactic nucleus M77, marking a milestone in neutrino astrophysics. The episode explains how the detector uses Cherenkov radiation in Antarctic ice to identify cosmic neutrinos, distinguishing them from atmospheric noise. It also discusses the physics of neutrino interactions, including the rare possibility of seeing them in the human eye, and answers viewer questions about the island of stability and quark matter.
