Earth has been hit by at least six extreme radiation events over the past 10,000 years, according to data in tree rings; These events, known as Miyake events, were thought to be caused by solar storms ...

They are called Miyake events after the lead author of the first study about such an event, detected in 1,200-year-old tree rings. The spikes in radiation turn up in isotopes of carbon, ...

We analyzed radioactive signatures left in tree rings around the world to study mysterious "radiation storms" that have swept over Earth half a dozen times in the past 10,000 years or so.. Our ...

University of Queensland. (2022, October 25). Tree rings offer insight into devastating radiation storms. ScienceDaily. Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2022 / 10 ...

Scientists have spotted six Miyake events in tree rings so far, indicated by sudden, single-year leaps in the concentrations of carbon-14 and other isotopes; these occurred in the years 7176 B.C ...

Over the years, tree ring data from around the world has shown evidence of several unexplained and potentially devastating space weather events that delivered a dose of radiation to Earth and many ...

Tree rings can preserve a snapshot of the Earth throughout the tree's life. Now Australian scientists analyzing these records have found evidence of huge radiation storms that periodically bathe ...

Tree rings record six known Miyake events — spikes in global radiation levels in the past. The sun, as long presumed, might not be the sole culprit.

“When radiation strikes the atmosphere it produces radioactive carbon-14, which filters through the air, oceans, plants, and animals, and produces an annual record of radiation in tree rings.
