Before the big explosion: The artist’s impression shows a binary star system where mass is transferred from a companion to a white dwarf. As soon as sufficient matter has collected on the surface of the dwarf star, this can trigger a nuclear explosion which in turn ignites the catastrophic nuclear burning and destroys the white dwarf – a type Ia supernova flares up.

The moment of detonation of a Type 1a supernova is modeled. This situation arises when a white dwarf star has accreted mass from a binary partner to a point when gravitational forces overcome the outward electron degeneracy pressure. The star collapses and it is thought that carbon fusion is initiated in the core, creating a supernova. (Credit: Argonne National Laboratory)
White Dwarf No More – The Type 1a supernova proceeds in the simulation, ripping through the white dwarf star. The star is completely destroyed. Around 1-2 × 1044 Joules of energy is released from Type 1a supernovae, ejecting matter and shock waves traveling at velocities of 3-12,000 miles per second (approximately 2-7% the speed of light).

In this picture, which combines views from Hubble and the Keck-II telescope on Hawaii (using adaptive optics), you can see a foreground galaxy that is acting as the gravitational lens. The galaxy resembles how our home galaxy, the Milky Way, would appear if seen edge-on. But around this galaxy there is an almost complete ring — the smeared out image of a star-forming galaxy merger far beyond. (Credit: NASA, ESA)
