How Supernovas Create (IMAGE) Princeton University Caption This snapshot of the explosion of a supernova in its first seconds, simulated by Princeton astrophysicist Adam Burrows and collaborators using supercomputer resources, shows an area more than 1,500 miles across. The outer surface is the blast wave, and the interior coloring is a rendering of the entropy ('heat') of the shocked material.
