It is postulated that towards the end of its life cycle, the sun will become a red giant, which will consume several of the inner planets, possible including the earth. Even if the diameter of the sun does not expand to the point where the earth is consumed, the increased heat and radiation due to the sun's closer proximity will exterminate life on earth. Eventually, the sun will collapse into a white dwarf.
At first, the sun will soon run out of its primary fuel, hydrogen. This will cause the sun's layers to expand, becoming a red giant. This will likely happen in 5 billion years. While scientists are unsure whether the expanded the sun will engulf the Earth or not, it will likely end life on Earth nonetheless.After it runs out of all fuel, including the heavier elements, it will begin shedding its outer layers and become a planetary nebula. Life on Earth would've almost certainly ceased by then.
first red giant then white dwarf ultimately DEAD
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
Fusion, 2 hydrogen atoms turning into one Helium atoms continuously. (until the hydrogen runs out)
Because a massive star has more pressure on the core, this creates greater temperatures, which increase the amount of nuclear fusion that occurs. This uses more hydrogen and thus the star runs out of fuel much quicker, that a smaller star.
Yes, but it is a long way off

this is what the scientist say when the sun reaches the end of it s life it will expand so much that all the planets in the solar system will be incinerated but you ned not worry this wont happen for a few billion years yet
