# Ancient Tree Rings Offer Warnings of Future Giant Solar Storms

Researchers are using growth rings in ancient trees to uncover evidence of past massive solar storms, including one far stronger than any seen in modern times. By dating these extreme space weather events, scientists can better assess the likelihood and potential impact of a similar storm hitting Earth. This matters because a direct hit could disrupt power grids, satellites, and global communications.
