About 14300 years ago, the most powerful solar storm ever occurred on earth. Scientists at Oulu University, Finland, discovered this by studying the amount of radiocarbons in the fossil rings of the trees. This storm can become a big threat to the world dependent on today’s technology.
What is a solar storm?
When the bright energy from the sun and the charged particles (protons) hit the atmosphere of the earth, it is called a solar storm. These particles shake the magnetic field of the Earth and increase the amount of radioactive elements called radiocarbon (carbon-14). Scientists find out the age of old things with the help of this radioacarbon.

14300 year old storm
Scientists saw the unusual growth of radiocarbons in the old rings of trees. New research showed that it was due to a solar storm that came from 12,350 BC (January to April). This storm was so powerful that it sent 500 times more energy to Earth than the 2003 Halloween solar storm. At that time there were mammath hunters in Europe, who might have seen the shining Aurora Boriyalis (northern lights) in the sky.
Earlier solar storm
Scientists also studied five major solar storms earlier, which came in 994 AD, 775 AD, 663 BC, 5259 BC and 7176 BC. The most powerful among them was the storm of 775 AD, which is mentioned in old Chinese and Anglo-Saxon documents. But the storm of 12,350 BC was even more powerful than 18%.
Today’s threat to
Today our world is dependent on satellite, electricity grid and communication system. In such a situation, such a big solar storm can cause heavy damage. The Carrington storm of 1859 burnt the telegraph wires. The 2003 Halloween storm, which was ten times weaker than this. This spoiled the satellite orbit. The 2024 ganon storm also shook the satellites. If the storms like 12,350 BC come today, it can completely stagnate satellite, electricity and internet.

New model, new discovery
Earlier scientists did not have the right way to understand the radioacarbon data of the ice age. But researcher Kshania Golubanko and his team at Oulu University created a new chemistry-climate model. With its help, he made accurate estimates of the strength and time of this ancient storm (12,350 BC). The discovery appeared on 15 May 2025 in the Earth and Planetary Sciences Letter Journal.
This storm is the worst scenario. We have to understand its danger so that satellite, electricity grid, and communication system can be saved in future. Scientists are now studying such storms so that our technology can be secured.
