Evidence of supernova explosions and super solar flares hidden in Earth’s history
Scientists have discovered new evidence that Earth has been bombarded by extreme cosmic radiation in the past, leaving “fingerprints” of supernova explosions and solar superflares in tree rings and ice cores. These rare events, known as Miyake Events, reveal sudden spikes in radiocarbon (¹⁴C) levels, suggesting that powerful cosmic forces — ranging from massive solar storms to nearby supernovae –may have impacted Earth’s atmosphere far more frequently than previously thought. A newly identified event from 12 350 BCE could be the most intense yet, challenging our understanding of space weather and cosmic threats to our planet.
