The WORST solar storm in history to hit Earth soon; facts are shocking

The worst recorded solar storm in history is the 1859 solar storm, better known as the Carrington event. It was so powerful that it caused sparks and fires in telegraph machines and caused power grid failures. However, if the entire history of the Earth is considered, this is not even close to what the planet has experienced. A study has analyzed tree ring data and found out that the worst solar storm to hit the Earth occurred in 774 CE in an event now known as the Miyake event and it was so powerful that the solar storm started multiple forest fires. And the worst part? It strikes every 1000 years. Know when it can impact us next.

The data comes from a study published in Nature journal where a group of Japanese researchers analyzed tree ring data to find out about the existence of this solar storm. According to it, this particular solar event took place between 774–775 CE. It is estimated that its intensity was 10 times higher than the Carrington event. The evidence was found in Cedar trees in Japan which all show a huge spike in carbon-14. What is truly interesting is the way these researchers confirmed that this spike in carbon - 14 as it is not conclusive evidence of a solar storm.

For years, analyzing tree rings have been used to determine the age of major historic events. This is done by checking the contents of tree rings and noting any peculiarities. But while a spike in radiocarbon would indicate a cosmic event, it does not necessarily have to be a solar storm. It could have been a supernova explosion as well. This is where another study conducted by a team of researchers led by mathematician Qingyuan Zhang of the University of Queensland, reports Science Alert. “We modeled the global carbon cycle to reconstruct
