[00:00:00]A supernova usually obliterates everything, but astronomers found a zombie star that refused to die.

[00:00:06]Historically, when a star explodes, it either collapses into a black hole or vanishes entirely. However, observations of SN2012Z revealed something impossible. The star actually survived its own titanic blast. This white dwarf underwent a partial thermonuclear explosion, blasting its outer layers into the cosmos while leaving a battered, glowing core behind.

[00:00:28]It is the first time we have ever seen a failed supernova create a stellar remnant that is physically brighter than it was before the explosion. This cosmic survivor is now rewriting our entire understanding of how stars end their lives, proving that even a total stellar meltdown isn't always the end.
