WebWhen a runaway thermonuclear explosion rips through a white dwarf star and blows the star to bits, it is called a type 1a supernova. These explosions are incredibly violent and … WebA supernova is the explosion of a giant star. It usually happens when its nuclear fusion cannot hold the core against its own gravity. The core collapses, and explodes. The …
