Scientists say the centuries-old evidence points to a cosmic blast powerful enough to disrupt life if it struck today.

Centuries-old trees have recorded more than just seasons—they’ve captured evidence of events far beyond Earth. Recent research into ancient tree rings uncovered signs of a solar superstorm so intense it left a lasting chemical fingerprint in the wood. The idea that our sun once unleashed such a powerful burst of energy is both fascinating and unsettling. If a storm of that magnitude happened again, it could upend modern life in ways our ancestors never had to imagine.
