The mysterious origin of the radiation that hit the Earth during the Middle Ages. A little over 1,200 years ago, the planet Earth was struck by a very intense burst of radiation at high energy of unknown origin. The phenomenon has been observed by scientists who study the amount of carbon-14 radioactive isotope formed in the rings of trees in 775 A.D. in the northern hemisphere.

Something inexplicable occurred on our planet about 1,200 years ago. In the course of a study on the amount of carbon-14 radioactive isotope in the rings of ancient trees, the researchers found that between 774 and 775 AD, the planet Earth was hit by a very intense burst of high-energy radiation, whose origin is entirely unknown. Radiocarbon is formed when high-energy radiation from space hit gl atoms in the upper atmosphere, producing neutrons. These collide with the nitrogen-14, then decaying Carbon-14. Normally, the continuous production of radiocarbon is powered by the cosmic microwave background.

However, the only events known to produce the peak of 14C in the Northern Hemisphere trees are the explosion of a supernova or a storm of protons produced by giant solar flare. But, none of these two phenomena seems likely, given that each of them would have to be powerful enough to cause effects that would have been widely noticed at that time. A supernova massive, for example, would be bright enough to produce a “new star” also visible by day, as in the case of similar events recorded in 1006 and in 1054.

To cause the peak found in the trees, the explosion would have to be much more intense than the latter two. It is possible that such an event could have occurred in the skies of the southern hemisphere, where the astronomers of the time they could not see him. But if so, the radio astronomers today would find the signs residues of this tremendously bright explosion. With regard to solar flares, the reasoning is similar: an event capable of producing very high energy protons and generate the observed peak greatly exceed any solar eruption ever recorded.

Historical accounts would certainly have reported extraordinary aurora at low latitudes.

Not to mention the huge blaze that would probably have wiped out the ozone layer, with devastating ecological consequences. Taking advantage of the uncertainty on the part of science to provide answers to the mysterious phenomenon, someone is driven to assume a cause that researchers have been unable, or unwilling, to consider. Assuming that there are many medieval reports which speak of strange flying objects, some daring think that radiation may have been issued by some non-terrestrial origin of the vehicle in orbit around the planet Earth. Indeed, perhaps the radiation is the result of an epic clash of alien craft in the vicinity of the Earth.

In a Agobard written manuscript of Lyons in the 9th century (Contra vulgi insulsam opinionem hail et de tonitruis), the bishop reported the strange tales by French farmers: “There’s a certain region called Magonia where they come from ships in the clouds. The occupants of these ships carry there the fruits of the earth that are destroyed by hail and storms”. The Archbishop writes that he also witnessed the stoning of three men and a woman fallen from one of these ships themselves.

Another testimony to fame is the so-called Manifesto of Nuremberg, a print that shows a celestial event took place in Nuremberg skies April 14, 1561. According to chronicles of the time, the population saw appear in the sky many flying objects of various shapes, which waged among themselves a kind of combat. The chronicles of the time reported the incident in great detail, so that the story remained clear memory. In addition, they were executed several woodcuts and prints on paper.
