Wolf–Rayet star

Nothing in the universe is immortal.. not even stars.

Stars also die..!!

What you see is a star belonging to the Wolf–Rayet class that is slowly dying.

What keeps a star alive is its fuel. Didn't we say before that the energy released through the process of hydrogen becoming helium through nuclear fusion keeps our sun alive..

The energy generated in this way exerts a pressure on the star..

But the star's gravity is released. It pulls this outward pressure inward..

This tug of war is what really balances a star.

Now, no matter how big the fire is, if the fuel to burn runs out, it will go out.. Similarly, when the hydrogen for fusion runs out, it will produce helium, carbon, oxygen and even iron through fusion. After this, without fusion, energy production stops and the outward pressure disappears.

When one side of the rope is suddenly released, the entire star is pulled towards its center by gravity. In this way, the extremely dense center begins to throw out all the elements that have been made so far. The elements that are thrown out in this way are used to build new stars and planets, and even our own bodies..!!

This state before the explosion of massive stars called supernovas is called a Wolf–Rayet star.

This star, known as WR 124, has been expanding outwards like this for the past 20,000 years.
