Today astronomers say they have solved an 840-year-old mystery in which two extremely dense stars in the Milky Way collided and caused a supernova.

Chinese and Japanese astronomers monitored a new light in the sky, in the twelfth century, dazzlingly shining like the planet Saturn, and astronomers expected that this light was the result of a massive explosion of the Probe Nova and roughly determined its location, but the reason for this explosion remained mysterious until today, as it disappeared after Only several months.

Today astronomers say they have solved an 840-year-old mystery in which two extremely dense stars in the Milky Way collided and caused a supernova.

According to the article published in the famous scientific journal “livescience”, it is possible that the explosion led to the emergence of a very hot star, known today as the Parker Star, with an expanding nebula of gas and dust called “Pa 30”.

This supernova, or the so-called Chinese guest star, was discovered in the year 1181 AD, and it remained visible from August 6 to February 6 of that year and disappeared after that. It is one of nine supernovae recorded historically in our galaxy.

A group of scientists was able to finally solve the mystery of this star, in a new research published in the Astrophysical Journal. Astronomers have identified some supernova remnants, but the Chinese guest star was the only supernova in the last millennium whose remnants have yet to be found.

Researchers previously suggested that Pa 30 and Parker were the result of the merger of two white dwarfs, two extremely dense stars that used up all their nuclear fuel. “.

In the new study, astronomers discovered that the nebula “Pa 30”, which was discovered in 2013. After calculating the speed of its expansion, it was inflating at a speed of 684 miles per second (1100 kilometers per second). Knowing this rate, scientists estimated that this star was born only about 1,000 years ago, meaning that its emergence was at the same time as the ancient supernova.

In turn, Albert Zilstra, professor of astrophysics at the University of Manchester, UK, said in a statement: “Historical reports place the guest star between two Chinese constellations, Quanxi and Huajai. The Parker star fits the location well… This means that the age and location correspond to the events of the year. 1181”.
