However, the stream of particles is particularly strong when a solar storm sweeps past.
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.
During that solar storm, the sun unleashed a series of powerful solar flares that were so powerful telegraph operators' offices experienced a surge in electricity which resulted in some buildings setting on fire.
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.
"Those storms took place in 775 CE and 994 CE".
"We also took part in research that confirmed the existence of two other massive solar storms, using both ice cores and the annual growth rings of old trees", Professor Muscheler explained. The latter was, to date, the biggest solar event on record.
In a study published in PNAS, Raimund Muscheler from Sweden's Lund University and colleagues found evidence of another huge solar storm on the same scale as the one that hit in A.D.
"Our research suggests that the risks are now underestimated".
"The first discovery of such an event was quite recent", Muscheler said. The researchers now plan to carry out a systematic search to better understand just how often big solar storms hit Earth, so we can be better prepared for them.
According to the researchers, the finding has provided a stark warning that another event of this size could not be too far away, a report in The Independent said.
"Our highly interconnected technological society has become vulnerable to disturbances from the sun", he told Newsweek.
For the past 70 years, researchers have studied these solar storms by direct instrumental observations, which has led to an understanding that they can pose a risk to the electrical grid, communication systems, satellites and air traffic.
Owens added, "This kind of work is vital to inform the engineering of space- and ground-based technologies in order that they are able to survive the worst-case space-weather scenario so that the sun doesn't catch us unprepared".
