@Skitz You are not completely correct either. Only very massive stars undergo core-collapse supernovae, not all stars. For example, our sun will NOT die with a supernova.
Not exactly, @RealisticHypernova. In a type 1A, the two do not collide. The one that began with more mass goes through it's life and becomes a white dwarf. When the other star gets old some of it's outer layers can spill onto the white dwarf. If the dwarf reaches a mass of 1.4 suns, it will explode in a type 1A supernova.
Arghh triple comments glitch
@Skitz A twin binary star orbit can eventually pull them together, this is type 1A. You only know 1B.
@Skitz A twin binary star orbit can eventually pull them together, this is type 1A, the one you are talking about is 1B, @b-tenthousand, it can be a binary star system too!

@below You are such an idiot. A supernova is the end of a stars life. It is when the core of the star is no longer able to create fusion, and gravity crushes it. The crushing of the core creates pressure waves, which then travel out and blow the star apart.
