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

"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 ...

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

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 ...

A solar radiation storm struck Earth 14,300 years ago, showering the planet with high-energy particles and leaving a spike in radiocarbon.

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 ...

The latest findings, published in the journal Earth and Planetary Science Letters, confirm that the extreme event from 14,300 years ago is nearly 20 per cent stronger than the notorious 775 AD solar ...

If a tree's rings are studied in a lab but no one hears them, do they make noise in the climate movement? An associate professor of oboe at the University of Arizona wondered. It led her to team ...
