Both tree ring and ice data pinpointed the date of the extreme Miyake solar storm whose timing had long eluded researchers to between 664 and 663 BCE. The study is published in the journal ...

These rings, like natural archives, record the fallout of cosmic interactions involving solar radiation and atmospheric carbon. Panyushkina's team has identified just six of these extraordinary ...

Severe space weather can leave a lasting mark in tree rings, offering clues that might help scientists prepare for future disruptive events that threaten communication satellites and astronauts. Amy ...

Most grade school kids know that they can count tree rings to learn how long they lived. Biologists and forensic scientists count cementum rings (these microscopic structures encircle a tooth's root ...

Some of those events can be linked to historical records — for instance, the avalanche that appears in tree rings dating to 1963 is probably a documented event that occurred on Feb. 12 of that year.

By examining tree rings from a buried French forest, researchers have unearthed evidence of a solar storm so powerful it would be like nothing we've ever seen so far from the Sun. Space weather ...

And in certain years, cosmic radiation spikes are recorded in the rings. The researchers IDed one of these carbon 14 spikes — from A.D. 774-75 — in the tree rings they sampled.
