Solar Super-Storm Hit Earth 2,610 Years Ago | Geoscience, Space Exploration

According to the team, the cores recorded a very powerful solar storm occurring in 600 BCE.

SPEs, also known as solar proton events, send tons of particles, such as high-energy protons, toward Earth, and when they hit our planet, they interact with Earth's atmosphere.

A similar event today could have a highly destructive effect on power grids, communications, GPS systems and information technology, warn scientists. With these ice samples, the team was able to find out when our planet was hit by the sun's high-energy cosmic waves and how it might have altered Earth at that time, Phys.org noted.

Presently an enlarged amount of research portrays that solar storm can be even more robust than measurements have portrayed till now through undeviating inspection.

Solar storms can be far more powerful than previously thought.

The event was at least 10 times more intense than any storm in the past 70 years-since modern records began.

The tell-tale signs were elevated levels of beryllium-10 and chlorine-36 isotopes embedded in the ice, both evidence of chemical reactions kicked off by the Sun's activity reaching through Earth's magnetic shield to the surface.

'That's why we must increase society's protection against solar storms, ' said Prof Muscheler.

Researchers found radioactive elements buried beneath almost half a kilometre of ice in Greenland, which shows an "enormous" solar storm battered the planet in 660 BC.

They found traces of chlorine and beryllium isotopes in the ice from the deadly storm over 2,500 years ago.

Professor Raimund Muscheler from Lund University and his colleagues from Korea, Sweden, United Arab Emirates, Switzerland, the United States, and France analyzed ice cores from Greenland in order to learn more about SPEs.

The cores emanate from Greenland and carry ice devised over the past about 100,000 years. 774-775. The latter is the largest solar eruption known to date. "There might be more that we have not yet discovered".

"We need to search systematically for these events in the environmental archives to get a good idea about the statistics - that is, the risks - for such events and also smaller events", Muscheler added.

On the basis of previous events, which have been identified between years 775 and 994, the scientists believe that these outbursts are probably a normal part of the Sun's cycle. Researchers are still a ways away from definitive estimates-but studying these prehistoric storms might be our best bet at forecasting future flare-ups.

The findings were published online this week in the Proceedings of the National Academy of Sciences.
