Uncovering a Forgotten Solar Storm: Lessons from the Past for Future Moon Missions The Okinawa Institute of Science and Technology's recent discovery of a deadly "red sky" solar storm from 800 years ago is a sobering reminder that our understanding of space weather is still in its infancy.
The team's innovative use of ancient tree rings and medieval records to uncover evidence of past solar proton events (SPEs) has shed new light on the Sun's behavior during this period.
The researchers' findings, published in the Proceedings of the Japan Academy, Series B, reveal that the Sun was much more active 800 years ago than previously thought.
