Supernova revealed star's inner layers

Astronomers observed a supernova revealing a star's inner layers for the first time, offering an unprecedented look deep inside a stellar explosion. The event, 2.2 billion light-years away, showed heavier elements like silicon and sulfur, indicating the star's outer shells were stripped before it exploded, confirming theories of stellar evolution. This rare observation, made possible by rapid telescope response, provides crucial evidence for models of stellar structure and the processes leading to supernovae.
