Ancient Tree Rings Uncover Solar Superstorm from 664 BCE
Researchers from the University of Arizona have identified a massive solar storm, known as a Miyake Event, that occurred around 664-663 BCE by analyzing tree rings and ice cores. These events, characterized by spikes in radioactive carbon-14 and beryllium-10 isotopes, are rare and could have catastrophic effects on modern technology if they occurred today. The study highlights the use of natural time capsules like ancient trees and ice cores to uncover historical solar activity.
