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 ...

The radiation burst, which seems to have hit between ad 774 and ad 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the ad 775 ...

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 ...

Trees which grew during intense radiation bursts in the past have 'time-markers' in their tree-rings that could help archaeologists date events from thousands of years ago Date: August 17, 2016 ...
