“Like Nothing Anyone Has Ever Seen Before” – Bizarre Supernova Stuns Scientists

A distant supernova exposed elements from a star’s core. The result reshapes ideas of how massive stars evolve. According to long-standing theory, stars are built in layers like onions, with each layer composed of different elements that grow heavier toward the core. While this model is widely ac

Even after the star was stripped down to its core, it continued to experience violent mass-loss episodes, ejecting shells of material rich in silicon (grey), sulfur (yellow), and argon (purple). Some of the explanations the team is considering are interactions with a companion star, unusual and extremely powerful stellar winds, and a massive eruption that preceded the supernova explosion.
