Scientists Witness Rare Supernova Core, Unveiling Cosmic Secrets
Astronomers observed a supernova, SN 2021yf, that revealed the star's inner layers of heavier elements like silicon, sulfur, and argon, challenging existing models of stellar death and suggesting a new, more violent pathway for massive stars to end their lives. This discovery supports some theories but also raises questions about the extent of material ejection before supernova explosions, indicating potential new types of stellar explosions.
