An international research team studied ice cores from Greenland and Antarctica and found traces of a powerful solar storm that struck Earth about 9,200 years ago.
The study was published in the journal Nature Communications, and a brief report on it is presented on the website of the University of Lund (Sweden). It is reported that the discovery of the order puzzled scientists. Dating showed that a powerful solar storm occurred about 9200 years ago, and the known scientific evidence suggests that at that time the Sun was in one of its most tranquil phases.
During such periods, our planet is thought to be least susceptible to solar geomagnetic storms. However, a new study proves that it is still very difficult for scientists to predict solar storms, and oddly enough, this also applies to Earth’s past.
