When a star's fuel has been spent, it explodes into a giant fireball known as a supernova, producing the brilliance of multiple suns and sometimes outshining entire galaxies. How these explosions occur has been a subject of observational and theoretical study for decades. In recent years, advances in supercomputing have enabled astronomers to simulate the internal conditions of stars with increasing sophistication, helping them to better understand the mechanics of stellar explosions. Yet, many details of what goes on inside a star leading up to an explosion, as well as how that explosion unfolds, remain a mystery.
