Country “Net revealed”NBC News“The American newspaper revealed the details of a rare and exceptional cosmic event that astronomers are anticipating for its occurrence in the coming months, which is called “NOVA,” or cosmic explosion.
This bright explosion that the Milky Way will witness occurs “once in a lifetime,” according to the report, and will be visible in the sky with the naked eye.
The date of the cosmic explosion in the Milky Way Galaxy
According to the agencyNASA“This cosmic explosion will be an opportunity to observe the sky for those living in the northern hemisphere, because the types of star systems in which such explosions occur are not common in the galaxy.
Astronomers expect that a supernova explosion could occur any time between now and next September.
Bradley Schaeffer, professor emeritus of physics and astronomy at Louisiana State University, stated that the last time this star system exploded was in 1946, and it is likely that another eruption will not occur for 80 years or so.
The stellar explosion is in a system called “T Coronae Borealis,” which is 3,000 light-years away from Earth, and contains two stars, a dead star, known as a “white dwarf,” around which a “red giant” star revolves.

It’s like a hydrogen bomb exploding in space
Red giant stars are dying stars, as the hydrogen fuel in their cores is exhausted. According to NASA, this is what the sun will eventually turn into.
According to an NBC News report, in systems such as T Coronae Borealis, the two stars are usually very close to each other, to the point that hydrogen fuel from the red giant is constantly flowing onto the surface of the white dwarf, and over time, This leads to increased pressure and heat, and eventually an explosion.
“As hydrogen fuel accumulates on the surface of the white dwarf, heating increases and higher and higher pressure occurs until explosion,” Bradley Schaefer said.
Schaefer likened the “nova” explosion to a hydrogen bomb exploding in space, adding that the resulting fireball would be able to be seen by people from Earth.
A nova explosion is different from a supernova explosion, which occurs when a massive star collapses and dies.
“At the peak of the eruption, the eruption should be visible to the naked eye, and it will be bright in the sky, so it is easy to see from the backyard,” Schaefer said.
