Particle physics
The Neutrino
A tiny, electrically neutral particle that interacts only very weakly and so streams almost unimpeded through matter — trillions pass through you each second. Neutrinos are produced in the Sun's core, in supernovae, and by cosmic rays, and detecting them opens a window onto processes hidden from light, a pillar of multi-messenger astronomy.
