According to the calculations of scientists now 4.5 billion years old Fortunately, the sun is not yet halfway through its life.
Life expectancy before death is approx. 7-8 billion years.
For the first 4-5 billion years of its remaining life, the sun will remain stable.

But when he drilled it out, he turned it into helium. Because it will completely empty the hydrogen tanks, it will start using hydrogen supplies in the outer layer that surrounds the core, which we can say acts as a kind of emergency.
As a result of this situation, the star, which gradually began to grow, completely changed from its current state over the next 2.5 billion years. It’s getting 200 times bigger.
The sun, whose extinction accelerated in the last 1 billion years of its life, began to convert the helium it contains into carbon, and it is now on a universal scale. will live his last days.
His energy will not even be enough to keep his outer layers close to himself, and he will be separated from each side. huge masses of gas will spread into space.

Contrary to popular belief, the sun is huge neither will it be destroyed by the explosion; while not as impressive, it will end its life by slowly dispersing all of its mass into space, leaving behind a hot mound of carbon and a giant nebula smaller than it is now.
So in this process, if there are still people on Earth, what will they experience?

First of all it must be said that; Earth, the last phases of the sun without seeing will have to disappear. Moreover, it will be the sun itself that destroys the earth.
Remember, we said the sun would expand after the hydrogen stores in the core were used up. This expansion will take place on such a gigantic scale that; First Mercury and Venus, then Earth and Mars are extremely strongly orbited by the Sun. will be easily swallowed.
Even before the period of engulfment, life on Earth will not be able to survive; because the sun will increase the temperature on Earth by thousands of degrees as it gets closer.
In short, the Earth does not expect a very good ending. Fortunately, those times were beyond our comprehension. of a distant future.
