What was the letter from Cygnus ten thousand years ago?

The letter from Cygnus 10,000 years ago is a discovery of human exploration of space. For the first time, China has detected a large number of ultra-high energy cosmic accelerators in the Milky Way. Moreover, according to the information of Cygnus, the highest electron volt-gamma photon recorded in China is 1.4, which is also the highest energy photon that human beings can detect, refreshing some traditional cognition of human beings and gradually entering the period of "super gamma literature".

The signal of Cygnus 10,000 years ago is actually a normal natural signal, which is just a major discovery of human beings in space exploration. This discovery is helpful for us to explore the origin of the universe and the evolution of celestial bodies, and has played a significant positive role in human exploration of space.

Understand cygnus

Cygnus is one of the northern constellations. Because its main star is arranged in a big cross, it used to be called the "Northern Cross". Under the cross is the swan's neck, and the horizontal one can be regarded as the swan's spreading wings.

The star of Cygnus is very bright, so it is easy to see it in the summer night sky. There is also a famous meteor shower in Cygnus, mostly fireballs with high brightness, which usually appears in late August every year. Interested friends can observe the night sky in late August. Cygnus is about 1500 light-years away from the earth. Because the ultra-high energy cosmic ray accelerator did not reach the speed of light, scientists can infer that this gamma photon appeared 1 10,000 years ago.
