This visualization shows the neutrino-driven roiling convection of the nuclear material behind the newly reenergized supernova shock wave that surrounds the newly birthed neutron star, just hundreds of milliseconds after shock revival. The neutrino-heated turbulent bubbles help drive the supernova explosion shock wave outwards. Image: Joseph A.
