neutrino
Chargeless subatomic lepton
A neutrino is a subatomic particle with almost no mass and no electric charge.
Neutrinos pass through ordinary matter virtually undetected—billions stream through your body every second without interacting.
They're produced by nuclear reactions in the sun, stars, and particle accelerators.
The detector captured a handful of neutrinos from the supernova.
