What are the records of supernova explosions in ancient times?

It has aroused great concern in astronomy, because limited by the observation level of modern humans, there are very few supernova explosions that can be studied comprehensively and closely.

1987 In the spring, astronomers observed the explosion of a supernova in the Large Magellanic Cloud galaxy about 160000 light years away from the Earth.

This discovery has aroused great concern in astronomy, because limited by the observation level of modern humans, there are very few supernova explosions that can be studied comprehensively and closely, and many modern astronomical theories need it to verify.

Not only in modern times, but also in ancient times, the astronomical phenomenon of supernova explosion was highly valued, because the ancients thought that supernova explosion was related to human happiness and misfortune, so it was recorded in detail.

However, through the historical documents in the past two thousand years, it can be confirmed that there are only 8 ~ 9 supernova explosions recorded: in A.D. 185, people saw a dazzling supernova explosion in the direction of Centauri, and according to the literature records, its magnitude can reach minus 8.

This supernova explosion will be visible to the naked eye within 20 months.

In 386 AD, another supernova appeared in Sagittarius, which lasted for three months and was visible to the naked eye.

Soon after, in 393, in the direction of Scorpio, people recorded another supernova explosion, which disappeared after 8 months in the sky.

For more than 600 years, there has been no record of supernova explosion.

Until l006, a supernova with amazing brightness appeared in the direction of the jackal constellation.

According to China's "History of Song Dynasty", when this supernova appeared in 1006, it was shaped like a half-moon with an awn angle, and the brightness was enough to see things.

In Europe, * * *, Japan, North Korea and other places, there are also records about this supernova. Even in the ancient Indian murals found in Arizona, there are images depicting this supernova explosion.

This supernova didn't disappear in the sky until several years later.

The most famous supernova in ancient times may be supernova l054.

This supernova appeared next to the star in Taurus, so people in ancient China called it "the guest star in the sky".

Supernova 1054 is so bright that it can be seen in the daytime for 23 days.

Later, according to records, astronomers observed a crab-shaped nebula with a telescope at the location of the supernova explosion in 1054. This is the famous Crab Nebula, the remnant of the supernova explosion in l054.

In 1 18 1 and 1408, two more supernovae appeared, one in Hou Xian and the other in Swan constellation.

The supernova explosion in AD 1572 was observed by the famous astronomer Tycho.

It was the Wanli period of Ming Dynasty in China. Emperor Wanli saw this supernova with his own eyes. Surprised and scared, he knelt down to it.

In the last year of his life, Tycho hired a young man who was proficient in mathematics as his assistant. This young man is the world-famous astronomer Kepler who later discovered the three laws of motion of the solar system.

Kepler discovered a supernova in Ophiuchus in 1604, and it can be seen at its brightest in the daytime.

This supernova stayed in the sky for a whole year before it disappeared from people's sight.

Unfortunately, people had not started to use astronomical telescopes at that time, and the observation of these supernovae could only rely on the naked eye, so it was impossible to leave a more detailed record.

In modern times when celestial observation technology has reached a high level, although some supernova explosions can be observed with telescopes, it is impossible to obtain rich information because of the very long distance.

1987 supernova can be said to be 1604 supernova explosion, and it is also used for comprehensive observation since the invention of astronomical telescope, so astronomers are quite interested in it.
