Will the sun explode one day?

Answer 1

The sun will not explode. It is not large enough for that.
It will slowly grow larger and collapse because of its own gravity and turn into a white dwarf.

Answer 2

The Sun is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation. The Sun will spend a total of approximately 10 billion years as a main sequence star.

The Sun does not have enough mass to explode as a supernova. Instead, in 4-5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up. Helium fusion will begin when the core temperature reaches around 100 MK, and will produce carbon and oxygen.

Following the red giant phase, intense thermal pulsations will cause the Sun to throw off its outer layers, forming a planetary nebula. The only object that will remain after the outer layers are ejected is the extremely hot stellar core, which will slowly cool and fade as a white dwarf over many billions of years. This stellar evolution scenario is typical of low- to medium-mass stars.

So no. In 4-5 billion years it will cook earth and then when it turns white dwarf it will freeze us. But it isn't big enough to explode, if you mean go nova.

Answer 3

It won't "explode", per say, but seeing as the sun is a young star, it will eventually get bigger until it becomes a "red giant"--and will probably destroy life on this planet for good.

Answer 4

I was quite impressed when I read about how the sun will become a red giant, and cook all life on the earth.
Seems to be in complete agreement with Biblical prophecy...God will not destroy life with a flood again...this time it will be with fire.
Or, as Peter puts it..."the elements will melt with fervent heat"....

Answer 5

Every star does when it runs out of fuel, but it expands before that, so it will engulf the inner planets anyway.

Time to pack up a colonize other solar systems.

Answer 6

Not all stars go supernova so it will cease to be at some point but it might not explode.

Answer 7

Yes I think it will. The scientists also say that it will.
Our sun has expended over half of it's energy.
When this happens to a sun, it can go nova anytime. The scientists say so.
If it does go nova, it will be in the twinkling of an eye. You will never know what hit you. Instant vaporization.

Answer 8

Not exactly. It is a young star. According to people who study those things in a couple of billion years it will get less hot, and also larger. I don't think it is a present concern.

Answer 9

There's no predictions that the sun will explode. They (scientists)predict that eventually the sun will burn out.

Answer 10

Well, it IS a star, so it will have to explode into a supernova in the far-off future.
