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 Sea Hint of Nearby Supernova: Could a 10-Million-Year-Old Explosion Have Shaped Earth?
The Mystery on the Pacific Seafloor Scientists have long hunted for signatures of past cosmic events that might have influenced life on Earth. This year, a German team reported an unusual spike in beryllium-10, a radioactive isotope created when cosmic rays hit Earth’s atmosphere, in Pacific Ocean sediments. The anomaly stands out because, while beryllium-10…

Nearby Supernova Hint from Pacific Be-10 Spike: Could a Stellar Explosion Reach Earth 10 Million Years Ago?
New Clues from the Deep Sea: A Be-10 Spike That Sparks Cosmic Questions A mysterious spike in the radioactive isotope beryllium-10 has researchers peering toward the stars. Found in a Pacific Ocean seabed deposit, the anomaly dates back roughly 10 million years and could be the remnant signature of a nearby supernova. Beryllium-10 forms when…

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…
