Massive Solar Storm Hit The Earth More Than Two Millennia Ago

15 March 2019

And while enormous solar storms are a rare occurrence, they seem to occur periodically, the researchers explained. After making this discovery, researchers revealed that these kinds of massive solar storms used to hit the earth more frequently than previously thought.

Should a similar event happen today, it could potentially destroy modern technological infrastructure such as those crucial to navigation and communication.

Although our planet's magnetic field keeps us blissfully unaware of it, the Earth is constantly being pelted with cosmic particles.

Solar storms are made up of high energy particles unleashed by explosions on the sun.

Leon Golub from the Harvard-Smithsonian Center for Astrophysics, who was not involved in the research, said the findings indicate a storm far bigger than the Carrington Event and hundreds of times larger than anything recorded during the space age. 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.

"This was a high level of particle radiation, ten times more than has been observed in the last 70 years", Raimund Muscheler, of Lund University in Sweden, said. "If..."

A strong wave of high-energy particles should be able to destroy most of the electronic devices which are now in use, including primary navigation and communication systems.

She spoke to reporters late Tuesday after a meeting of the Council of Ministers held in Maputo to discuss the deadly flooding. Flooding has also destroyed more than 5,700 homes and impacted more than 140,000 people in the southern African country.

Previous research found that extreme proton storms can generate radioactive atoms of beryllium-10, chlorine-36 and carbon-14 in the atmosphere.

The team of scientists, which examined the chemicals preserved in Greenland ice sheet, concluded that the storm was almost 10 times stronger than anything detected in past 70 years of modern measurements. Ancient ice cores, including the samples from Greenland featured in the study, could contain spikes of beryllium-10 and chlorine-36 from SPEs.

"That's why we must increase society's protection against solar storms", Muscheler added, Forbes reported. 774-775. The latter is the largest solar eruption known to date.

"Our research suggests that the risks are now underestimated". A new study has chose 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. "We need to be better prepared", says Muscheler.

"Those storms took place in 775 CE and 994 CE".
