One of the strongest known solar storms blasted Earth in 660 B.C.

Author: Carolyn Gramling / Source: Science News

charged solar particles and Earth's magnetosphere
Swift, powerful bursts of charged particles emitted by the sun can be strong enough to breach Earth’s magnetosphere (blue bubble in illustration). To see how common such emissions have been in Earth’s past, scientists look for telltale data in tree rings and ice cores.

One of the strongest solar storms ever to hurtle toward Earth blasted the planet in 660 B.C., researchers say, based on traces of the storm preserved in both ice cores and tree rings. The study was published online March 11 in Proceedings of the National Academy of Sciences.

As the sun’s magnetic field shifts, it occasionally releases bursts of charged particles into space. In the most extreme solar storms, called solar proton events, these charged particles are dramatically sped up by interactions with other solar emissions: solar flares or coronal mass ejections. Even…
