In 2024, the cosmic monster in the 13th century ancient text will return.

 In 1217, a German monk looked up at the southwestern sky and noticed a star suddenly transformed into a "cosmic monster", burning for days.

The event in 1217 was chronicled by the monk Abbott Burchard, head of the medieval Ursberg Abbey in Germany. He described it as 'a wonderful sign' , a mysterious object shining brightly in the constellation of Corona for many days.

According to Live Science, a group of scientists led by astronomer Bradley E. Schaefer of Louisiana State University (USA) studied this ancient text and also gave a similar description.

They identified it as the object that had been recorded by modern science through astronomical observations twice in 1866 and 1946.

It's a real cosmic monster: The "vampire" star called T CrB is located in the constellation Corona.

It currently remains in the sky as a completely normal star, but calculations show that in 2024 it will appear again in a "monster" form, like a blazing fireball in the sky for several days.

Because it is a "nova".

A nova is a stellar explosion that resembles a "dying death" event. The cause is that T CrB is a white dwarf - a "zombie" star that is the remains of a star like our Sun.

T CrB is not alone like the Sun, but has a younger companion star. As a white dwarf, it has shown 'vampire' behavior , constantly sucking material from its companion. About every 80 years, this star will become too full and explode in a nova event .

Calculations show the next explosive event is in 2024.

In theory, there will come a day when T CrB, like other vampire stars, will eat too much and "burst its belly" , completely exploding in a more violent event called a "supernova" . That will be the day it dies completely .

Scientists believe that T CrB is the same unexplained object that has been suspected to be a comet in other ancient texts. They hope that this 'identification' will help to better refine the tracking and prediction models for this particular star.
