Scientists in Japan recently made a discovery that has sparked great interest – traces of a mysterious radiation that appeared on Earth in 774. Now, another group of researchers claims to have found the solution to this puzzle, suggesting that the radiation wave was linked to the appearance of a blood-red cross in the sky.
The Japanese researchers base their claims on the increase in the concentration of the radioactive isotope carbon-14 in the atmosphere, which must have increased by more than 1.2 percent within a year. However, there are inconsistencies with this discovery, as there are no known supernova explosions or massive solar flares that could explain the presence of this radiation.
However, among the very brief records from that period, an interesting description of a red cross in the sky was found. The Anglo-Saxon Chronicle mentions this phenomenon, which appeared before sunset around the year 775. One possible explanation for this phenomenon is a supernova hidden behind a thick cloud of dust, scattering light and effectively blocking X-ray radiation.
It is also worth mentioning that a similar phenomenon was observed in 993 or 994. In both cases, different factors related to a powerful flare on the surface of the Sun were said to be responsible for the increase in the concentration of the radioactive isotope carbon-14 in the atmosphere.
Studies suggest that similar events may occur in the future, which is worrisome. In present times, with advanced technology, the consequences of such phenomena can be catastrophic for energy, communication, and satellite navigation. Until scientists are able to understand and predict these threats, all we can do is observe the sky and contemplate the mysterious forces of the cosmos.
