A star exploded in three months, producing a new star


,- For the first time in 80 years, the phenomenon of the sky will adorn our night sky. It will be an opportunity once in a lifetime to see the massive explosion of stars with the naked eye.

This star, called T Coronae Borealis, or T CrB, is in the northern hemisphere, 3,000 light years from Earth.

According to NASA, the "Blaze Star", officially called the T Coronae Borealis (T CrB), is expected to shine significantly from magnitudo +10 (beyond naked eye sight) to magnitude +2 between now and September 2024.

It's almost as bright as the 48th brightest star in the night sky, Polaris.
The Northern Crown, also called the Corona Borealis, is a small constellation in the northern hemisphere. A half-circular bow of stars resembling a crown is in it.

Alphecca or Gemma, which is a binary eclipse system, is the brightest star in the constellation.

T CrB, a recurring nova located in the constellation Corona Borealis, consists of a white dwarf and a red giant star orbiting nearby.

The imminent explosion, called the nova, is a rare sky event that occurs roughly every century.

It happens when a white  dwarf star collapses, which is about the size of the Sun, and a red giant star, which approaches the end of its lifetime and expands to about 74 times the sun's size.

The surface temperature of the red giant star increased significantly from approximately 4,000 to 5,800 degrees Fahrenheit to 360,000 degrees as a result of this proximity. It pushes the T CrB to release its outer layer from the surface of the white frog.

This peak of red giant matter triggers a nuclear explosion that produces up to 100,000 times more energy than the sun produces every year.

Nova like T CrB doesn't destroy a star system like the supernova that destroyed it. On the contrary, the star cools to its original temperature and starts its cycle again.

This particular star explosion is unique because of its short but intense appearance, completing its cycle in just a week. 

NASA predicts that the luminosity peak of the nova will allow it to be seen with the naked eye for a few days, and with the blindness for more than a week, before fading, and potentially not appearing again for the next 80 years.
