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

Radioactive particles from huge solar storm found in Greenland Evidence of Enormous, 2600-Year-Old Solar Storm Found in Greenland

For those alive at the time, the only major noticeable effect of the massive solar storms would be that the northern lights would be visible at very low latitudes.

The team write in the Proceedings of the National Academy of Sciences: "A solar proton event of such magnitude occurring in modern times could result in severe disruption of satellite-based technologies, high frequency radio communication and space-based navigation systems".

Although our planet's magnetic field keeps us blissfully unaware of it, the Earth is constantly being pelted with cosmic particles. Solar storms consist of high energy particles released from the Sun by flare up on the star's surface.

The find shows that the danger of solar storms has been "underestimated", the researchers say. But this study shows that the sun is capable of producing far more energetic-and possibly more damaging-events than we've witnessed in the last 50 years.

"If that solar storm had occurred today, it could have had severe effects on our high-tech society", says Raimund Muscheler, professor of geology at Lund University.

They've also reportedly urged others to refuse doing interviews with production house Pulse Films , who's making the series. We are aware that Netflix are planning to screen a documentary in March 2019 about Madeleine's disappearance.

Solar storms can be even more powerful than what our measurements so far have indicated - and we're still very unprepared.

"That's why we must increase society's protection again solar storms".

By drilling deep into 100,000-year-old ice in Greenland, researchers found radioactive evidence of an "extreme solar event" that occurred around the year 660 BC - a period that coincides with the dissolution of the once-mighty Assyrian Empire, the construction of the Acropolis in Athens and the founding of Taoism in China.

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. The researchers have utilized drilled specimens of ice or ice cores to search clues about former solar storms. 774-775. The latter is the largest solar eruption known to date.

This finding should motivate us to review the possibility that a similar event will take place sooner or later - and we should prepare. A new study has made a decision to analyze ice cores (samples of ice which are recovered from glaciers and zones where the ice is ancient) as they aimed to learn more about the phenomenon and how it can influence the world. "Assets in space, including satellites and humans, need to be protected, and even systems on the ground are at risk from large solar events". "We just looked at the last 3,000 years, and we certainly can get good enough data for the past 12,000 years".
