Forecasts that failed in 2025

Some media overestimate their predictions when they predict when T Coronae Borealis will explode in nova, they predicted in what month the year it would explode, and they even dared what day, I don't know where they got the imminence that it was going to be in March, even on the 27th, in the end it did not explode, it did not explode because the margin is actually quite wide, it is from 2024 to 2027, this does not mean that this Christmas, the end of the year, or the coming months we illuminate, with its brilliance and splendor.

Don't expect much either because the splendor is a nova, it is not a supernova, it is below, it would be a brightness similar to the polar star, so it is visible, it will be a new star, quite intense, but it will not be something spectacular, It's going to explode, why do we know? because it explodes several times, there are records from the Middle Ages of this nova, it is not a danger, yes, because it is 3000 light years from us and it is not a star, it is two that orbit each other.

It is a red giant that is approaching the end of its life, and a white dwarf that is a stellar corpse, it is the remains of a star like the sun, the sun when it ends its life as a star and dies, it will end up transforming into a white dwarf, a white dwarf is the size of the earth, more or less. It is more or less the diameter of the Earth, but if its mass is concentrated, the Sun will lose half of its mass. The solar corpse transformed into white would be the size of the Earth, but with the mass of half the Sun, that is, it would be very dense.

That dense white lullaby is stealing red giant gas that is less dense and therefore has less capacity for gravitational attraction, mass is important for gravity, but density is even more important, especially when we talk about this type of extreme densities, the process is that the gas falls into the white dwarf, but the white dwarf is no longer a star, it is a stellar corpse, no matter how much material you put into the white dwarf, it will not be a star again, since stars generate nuclear reactions in their core and White dwarfs have their core dead, literally.

So the matter is compacted on the surface of the white dwarf and there comes a point where an explosive reaction occurs, the nova, when it explodes, will appear in the sky as a new star, similar in magnitude to the North Star, it will not be visible to the naked eye during the day, but at night it will illuminate a lot because the North Star is quite visible, but I already told you that it can illuminate this Christmas or at the end of 2027, the range is from 2024 to 2027.
