Deep-Sea Crust Uncovers Steady Plutonium Rain From Ancient Kilonova Debris
A team led by researchers at Germany’s Helmholtz‑Zentrum Dresden‑Rossendorf analyzed a 1.9‑kg ferromanganese crust from the Pacific seabed, uncovering a steady influx of the long‑lived isotope plutonium‑244 over the past 100 million years. The uniform distribution of a few hundred Pu‑244 atoms, coupled with the absence of the shorter‑lived curium‑247, points to a kilonova—likely a neutron‑star merger—that occurred more than 100 million years ago. Measurements were made possible by ANSTO’s ultra‑sensitive accelerator mass spectrometry, the world’s most precise instrument for rare‑isotope detection. The results reinforce the role of kilonovae in producing heavy r‑process elements and open new avenues for tracing ancient cosmic events in Earth’s geological record.
