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…

Pacific Be-10 Spike Suggests Nearby Ancient Supernova
Overview: A surprising isotopic signal in Pacific sediments Scientists have identified an unusual spike in the radioactive isotope beryllium-10 (Be-10) in ocean sediments from the Pacific Ocean. Because Be-10 forms when cosmic rays strike Earth’s atmosphere, such a spike can act as a cosmic fingerprint, potentially recording a nearby stellar explosion in Earth’s distant past.…

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…

Earth’s Magnetic Field Reversal: An Eerie Soundscape from Laschamps
Introduction: science meets sound In a striking fusion of geophysics and art, scientists have translated Earth’s ancient magnetic field collapse into an evocative soundscape. The project recreates the 41,000-year-old geomagnetic excursion that briefly flipped Earth’s field, offering a rare, auditory window into a past planet-wide upheaval. By weaving data from the European Space Agency (ESA)…

Earth’s Magnetic Field Collapse: An Eerie Soundscape
Listening to Earth’s Past: A Scientific Soundscape In a striking blend of science and art, researchers have recreated a haunting audio portrait of a distant geomagnetic event—the Laschamp excursion, when Earth’s magnetic field briefly flipped about 41,000 years ago. A collaboration between the Technical University of Denmark and the German Research Center for Geosciences, and…
