Other researchers are also working on new protection methods which should be able to shield our sensitive electronics from the harm that can be caused by the high-power particles of a strong solar storm.

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.

A solar storm occurs when explosions on the sun's surface blast high-energy particles into the cosmos.

Since evidence has pointed to three massive solar storms taking place in the last 3,000 years, the scientists plan to explore more ice core samples to better understand these odd phenomenons.

Presently an enlarged amount of research portrays that solar storm can be even more robust than measurements have portrayed till now through undeviating inspection. Both the Quebec and Malmö incidents show how deeply massive solar storms can impact our technology, and how vulnerable our society is to them today.

Solar storms can be far more powerful than previously thought.

Scientists have analyzed proton storms for less than a century.

The team made this observation after studying a band of radioactive elements, unleashed by a storm that struck the planet in 660 BC, preserved in the ice almost half a kilometre beneath the surface. When high energy particles slam into the stratosphere, they collide with atomic nuclei to create radioactive isotopes of elements such as carbon, beryllium and chlorine. The cores come from Greenland and contain ice formed over the past 100,000 years. 774-775. The latter is the largest solar eruption known to date. This event can be compared to the strongest SPE detected at 775 CE, and it is only the third of its kind.

The biggest storm in the technological era was the Carrington Event which occurred in September 1859. "There might be more that we have not yet discovered". However, if these ancient solar outbursts "were connected with a geomagnetic storm, I would assume that they would exceed the worst-case scenarios that are often based on Carrington-type events", he noted. "We need to be better prepared", concludes Muscheler.

Although more research is needed to see how much damage such eruptions might inflict, this work suggests "these enormous events are a recurring feature of the sun - we now have three big events during the past 3,000 years", Muscheler said. "The challenge will be to find the smaller ones that probably still exceed anything we measured in recent decades".

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