Supernova mixing traced as source of key life elements
Tokyo, Japan (SPX) Dec 05, 2025
Kyoto University and Meiji University researchers have used the XRISM X-ray satellite to quantify chlorine and potassium in the Cassiopeia A supernova remnant, addressing a longstanding gap in how the universe produced these life-related elements. The work examines why current stellar models yield only about one-tenth of the chlorine and potassium inferred from observations across the cosmos.
