Tree Rings Unlock Evidence of Mysterious Cosmic Radiation 'Storms'

So scientists turn to unlikely sources, like tree rings, for data on cosmic events that predate Galileo.

“The leading theory is that they are huge solar flares.”

Their study findings appear inProceedings of the Royal Society A.

When the blast hit Earth, it reportedly caused telegraph lines to burst into flames and generated global auroras.

“The effect on global infrastructure would be unimaginable.”

It isn’t exactly good news that we could be overdue for a year-long global radiation event.

“These odds are quite alarming, and lay the foundation for further research.”
