Sacrifices of “sun stones” occurred around the same time a volcanic eruption in 2900 BC dimmed the sun throughout Northern Europe, according to a new study.

A solar explosion called a coronal mass ejection is poised to graze Earth on Friday or Saturday (Jan. 24 or Jan. 25), potentially triggering colorful auroras over the northern U.S.
