Ancient Supernova Imprint in Pacific: Be-10 Spike Evidence
The Be-10 Spike: A Cosmic Fingerprint in Ocean Sediments A remarkable spike in the radioactive isotope beryllium-10 has been detected in sediments from the Pacific Ocean. Beryllium-10 is produced when cosmic rays strike Earth’s atmosphere, leaving a chemical signature that can reveal past astronomical events. The researchers suggest that this spike could point to a…

Mysterious Be-10 Spike in Pacific Ocean Points to Possible Nearby Supernova
Stellar Echoes on Earth: A Be-10 Anomaly Emerges A surprising signal has emerged from the depths of the Pacific Ocean: a spike in the radioactive isotope beryllium-10 (Be-10) embedded in seafloor sediments. Be-10 is formed when cosmic rays collide with atoms in Earth’s atmosphere, showering the surface with particles that eventually settle into the oceans…
