neutrino emission in supernovae

Neutrino emission in supernovae occurs when a massive star's core collapses under gravity, causing extreme temperatures and densities. During this process, a large number of neutrinos—tiny, nearly massless particles—are produced as the core's protons and neutrons interact and transform, releasing enormous energy. These neutrinos carry away most of the explosion’s energy, escaping almost unimpeded due to their weak interactions, and play a crucial role in driving the explosion and dispersing elements into space, contributing to the birth of new stars and planets.
