Earth is no stranger to solar storms. Just this year we've been bombarded with storms, some so powerful they've triggered jaw-dropping auroras deep into mid-latitudes.

Meanwhile, skywatchers turn their gaze and cameras skyward to capture the mesmerizing auroras ignited by geomagnetic storms. But what about solar storms that took place prior to the creation of modern technology? If a solar storm of unprecedented magnitude occurred thousands of years ago how would we know?
