Amazing! They reveal the way the Sun will die

UNITED STATES.- Many times people have wondered how the Sun, because like any star it has a beginning and, therefore, an end. For this reason it has been revealed that our star will “say goodbye” when the hydrogen in it runs out, as it is the fuel it feeds on. Therefore, in the Intra News We will tell you all about this question that addresses the astronomy.

First of all, it is important to note that the Sun feeds on nuclear fusion reactions, so this is how its energy is generated. Thus, when this stops happening, the star of our system will begin to fade and the pressure that it has inside will decrease, which produces a contraction and an increase in temperature, but the good news is that there is a long way to go.

It is estimated that the so-called red giant stage, which is when it burns the hydrogen that remains in the outermost layers and causing a considerable increase in its size, will last 5 billion years. Thus, the total fuel of the Sun will be completely exhausted and it will enter its terminal phase. In addition, let us remember that the increase in temperature means that much heavier elements can fuse.

In turn, it was reported that in the last stage of the Sun there is a contraction in its size, so that whenever this process begins there is no way to reverse it, becoming a “white dwarf” the size of the Earth, but with a powerful density. Thus, the core of the star will be its main composition and the outer layers will “escape” in the form of a cloud of bright gas, a product of radiation.

Ultimately, all of this amazing process as a whole is known as a planetary nebula, which is defined as a bright expanding envelope of plasma and ionized gas. But for this we will have to wait 5 billion years, something that is extremely distant. For now, the only thing that will come sooner will be the fusion of our galaxy with Andromeda, which will occur in 4 billion years.
