Supernova

Caption

This is the core of a core-collapse supernova at the onset of explosion. Neutrinos that are emitted from the protoneutron at the center (bluish sphere) are absorbed by the gas behind the shock front, heat up this gas, and drive turbulence. Eventually an asymmetric explosion develops.
