Decoding the phenomenon of East Asia sky blazing throughout 9 days in 1770

Thanks to a number of rare records that have survived to this day, scientists who know East Asia, including some countries like Korea, Japan, Korea and the East China coast, have happened to be elected. the sky was dyed red for many days in 1770.

In the past, the sky turned red as a mysterious phenomenon. It was not until modern astronomy developed and understood more about aurora, that scientists could explain this phenomenon. According to them, the cause of this strange phenomenon is that the magnetic storm caused by the Sun's activity may have affected the Earth's atmosphere.

A 111 East Asian historical documents discovered by Japanese researchers, the phenomenon of the sky being dyed red is not only happened in two days like the previous view but lasted for 9 days, from 10-19 / 9/1770. And the sky affected is twice as large as the original estimate of historians. Scientists believe that this may be the longest, strongest typhoon in history.

Aurora is an optical phenomenon formed by the interaction of charged particles with the Earth's upper atmosphere. When solar-like phenomena occur, the Sun releases charged particles into space. They collide and stimulate oxygen and nitrogen in the Earth's atmosphere. When returning to normal, these gases release excess energy in various forms of light of different colors.

Although the exact factor determining the shape and size of light has not been determined, scientists believe that the movement of the Earth's magnetic field is crucial.

The gas that charged particles will determine aurora color, with oxygen being light green and red. This means that the mysterious natural phenomenon that occurred in 1770 could be caused by oxygen and the storm from that year was so strong that it hit the place where oxygen was more dense, the atmosphere was lower, making a wide area of ​​the sky big red turn many days continuously.

Today, modern society depends very much on large-scale grid systems and satellites. If the Earth had a similar phenomenon, the satellites, electrical systems and communication networks were seriously affected, causing losses of up to trillions of dollars.
