This isotopic anomaly points to formation in extreme cold (below ~−406°F), implying a very different birth environment. By reading these molecular ratios, astronomers treat such visitors as preserved records of distant planetary systems, offering direct constraints on how chemistry varies across the galaxy. Thank you for listening to Bedtime Astronomy — your guide to the cosmos. New episodes on space exploration, NASA missions &amp; the latest astronomy breakthroughs.
