💥 When a star explodes… how long does it actually take? The answer depends on what part of the explosion you’re talking about! ✨ The core collapse of a massive star? Less than a second! The core compresses into a neutron star or black hole almost instantly. ✨ The explosion phase? That takes seconds to minutes. A shockwave, re-energised by a flood of neutrinos, blasts the star’s outer layers into space. ✨ The bright phase we see from Earth? That unfolds over days to weeks, staying visible for mo

They saw silicon. Sulfur. Argon. Elements that normally lie buried deep inside a star’s core. This wasn’t supposed to be possible. According to stellar models, massive stars are built like onions.
