Ancient supernova signature found in Pacific sediments
What the spike means A recent international study has uncovered an unusual spike in beryllium-10 (Be-10) within Pacific Ocean sediments. Be-10 is a radioactive isotope produced when cosmic rays collide with Earth’s atmosphere. Its presence in higher-than-normal amounts can act as a cosmic fingerprint, offering clues about dramatic astronomical events that may have influenced our…
