The star’s chemically rich environment contains ten molecular species, including an unusual sulfur isotope imbalance linked to intense ultraviolet radiation. The discovery offers new clues about how dying stars distribute the elements needed to build planets—and potentially life. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
