Astronomers have found a way to predict only exploding supernovae

Wouldn’t it be great to know that a giant star is about to die in a cataclysmic supernova explosion? A team of astronomers did just that. If you see a red giant star surrounded by a thick layer of material, be careful – the star will likely explode within a few years.

As a massive star approaches the end of its life, it goes through several violent phases. Deep in the star’s core, it changes from combining hydrogen, starting with helium, to combining heavier elements and combining carbon, oxygen, magnesium, and silicon. A star forms iron in its core at the end of the chain. This spells the end of the star, as the iron dissipates the energy instead of releasing it, and in less than ten minutes, it transforms in an explosion of its own. supernova.
