Description: This is the image of a computer (FLASH) simulation of the "Deflagration to Detonation Transition" (DDT) model of a Type Ia supernova. The green surface approximates the surface of the white dwarf and the yellow/orange surface represents a flame surface behind which there is ash from the burning stellar material that has made its way to the surface of the star. The large smooth structures in the ash near the surface are regions where the flame has transitioned to a detonation in the model. A supernova is a stellar explosion that is more energetic than a nova. The model is developed at the Argonne Leadership Computing Facility (ALCF).
