My go-to guy for all cosmic things Prof. Geraint Lewis, astrophysicist at the University of Sydney, returns to unpack a fascinating New York Times article on a newly observed "onionlike" space explosion that may reveal a new type of supernova. We dive into what actually happens when a star dies, the onion-layer buildup of elements through nuclear fusion, and how these cataclysmic blasts forge the building blocks of life on Earth. Plus, we explore what this might mean for the ultimate fate of our own Sun. www.geraintflewis.com/ Linkedin: Geriant Lewis
