The distribution of the debris of an explosion of the core of a 23-solar-mass progenitor model at ~4.3 seconds after core bounce and ~4.0 seconds after explosion. The physical scale is ~40,000 kilometers on a side. The outer translucent veil is the shock wave. The globular structures trace the debris with a preponderance of the isotope Ni-56. The coloring is in mass density, with blue being lower density and red being higher density. This is the longest-duration 3D full-physics core-collapse supernova calculation ever performed.
