| Περίληψη: | The article focuses on the discovery and implications of extreme solar storms, known as Miyake events, identified through elevated carbon-14 levels in ancient tree rings worldwide. These events, first detected in Japanese cedar trees from AD 774–775, indicate solar superflares far more powerful than the largest recorded storm in modern history, the 1859 Carrington event. Research suggests Miyake events occur roughly every 2,000 years, with intermediate-strength storms possibly happening every 200 years, posing significant risks to modern infrastructure such as power grids and satellites. The study of diverse long-lived trees, including New Zealand kauri, helps refine the frequency and impact of these solar phenomena, which challenge existing solar physics models and highlight the need for global monitoring to better prepare for future solar storms.
