Astrophysicist Steve Schulze, a research associate at Northwestern University’s Center for Interdisciplinary Exploration and Research in Astrophysics, discusses groundbreaking discoveries about supernovae. He reveals what lies beneath the hydrogen and helium of stars, particularly in the case of supernova 2021yfj, which showcased a silicon- and sulfur-rich inner shell after its outer layers were stripped away. Schulze compares the structure of stars to a cosmic onion, uncovering layers of complexity and intriguing questions about stellar composition and evolution.
