In a nutshell Scientists have identified the most powerful solar storm ever recorded, an extreme event that struck Earth ...

A study published in the journal Earth and Planetary Science Letters has uncovered evidence of an extreme ancient solar storm ...

"We measured the 14C levels in the pine sample at three different ... may have caused the unusual tree ring data." Although the poor understanding of the mechanisms behind unusual solar activity ...

And, these changes can be seen in the tree rings, which absorb carbon in the air. ‘We measured the 14C levels in the pine sample at three different laboratories in Japan, the US, and ...

New findings suggest that a mysterious solar event roughly 500 times more powerful than any recorded by scientists struck the ...

The researchers used both tree ring analysis and radiocarbon dating to establish the age of the roots. The type of carbon used for the measurements, 14C, pinpoints the time at which the carbon ...

14C-Ex model to assess the solar particle storm intensity under glacial conditions. The model was successfully validated using data in tree rings from the AD 775 event and applied to the late Ice ...
