Medieval Japanese Verse Pinpoints a Solar Storm, Now Validated by Modern Science

A 1204 CE Japanese poem describing “red lights in the northern sky” is linked to a powerful solar storm. By combining historical records with tree-ring carbon-14 dating (dendrochronology), researchers confirm a medieval solar event and a shorter 7–8 year solar cycle, also identifying sub-extreme solar proton events that could threaten today’s technology.

Cosmic Rays Accurately Date 7,000-Year-Old Greek Settlement

Researchers at the University of Bern have precisely dated a prehistoric farming settlement in northern Greece to between 5328 and 5140 BC using dendrochronology and a significant radiocarbon spike from a cosmic event in 5259 BC. This breakthrough provides a reliable chronological reference for other Southeast European archaeological sites and marks a paradigm shift in dating prehistoric periods, especially in regions without consistent tree-ring chronologies.
