For many years, scientists and stargazers have tried to explain a strange cosmic phenomenon that occurred in AD 1181. For a brief moment, the sky over China and Japan shone brightly. So far no one has been able to post the perfect solution, which is not surprising.
Spreads at 1100 km/s
The mystery is illustrated by the Pa 30 nebula – also known as the Parker Star, one of the hottest nebulae in our galaxy, which may be a remnant of this explosion, according to the portal. Science alert.
Observations show that the cloud of dust and gases from the Pa 30 nebula is spreading at a speed of up to 1,100 kilometers per second. This speed indicates that the explosion occurred here about a thousand years ago and may be the result of a supernova explosion. And it was the supernova explosion that Chinese and Japanese astronomers were able to observe, according to a study published in Astrophysical Journal Letters.
“Recorded historical observations place Parker’s star between the Chinese planets Chuanshe and Huagai,” He says astrophysicist Albert Zigglestra from the University of Manchester. According to him, it is appropriate and means that the age and location correspond to the events of 1181.
Observers reported a bright object in the sky that remained visible for up to six months.
Pa 30 is believed to have formed as a result of the merger of two white dwarfs, a rare phenomenon that leaves a type Iax supernova, also called a zombie star.
They are a rare class of supernovae that astronomers don’t know much about. Even rarer is the information about how the supernova formed as well as what remains left behind.
“Only 10 percent of supernovae are of this type and are not well understood,Zigglestra says. As he says, this is the only event in which it is possible to study the remaining nebula and also obtain a description of the eruption itself.
“This is the only type Iax supernova where the nebula and the remaining star can be studied in detail. It is good to be able to solve a historical and astronomical mystery,He says.
