The Sun is a huge nuclear furnace. It operates by converting hydrogen into helium. In this process, which is called nuclear fusion, it loses mass and produces energy according to Einstein's famous equation: E=mc^2. This energy is dissipated in the form of light that we see and heat that we feel. In addition, some of this energy comes as X-rays, and a host of accelerated particles.
Our Sun has been converting hydrogen into helium for approximately 4.5 billion years. During this period it has converted 25% of its total mass into helium. About 75% of its mass is still hydrogen, and a very small remaining fraction accounts for oxygen, carbon and other elements. Based on a crude extrapolation, one would think that everything would be just fine for at least the next 13.5 billion years; however this is not the case.

The latest estimates show that our Sun will start dying approximately 5 billion years from now. What will happen to it? It will first gradually become brighter; in 5 billion years it will be about twice as bright as it is today. Then the internal energy from the fusion will start decreasing as the hydrogen becomes scarce. Gravity will win and the Sun's core will collapse on itself. This collapse will produce enough heat that the outer layers will expand violently, engulfing Mercury, stripping Venus of its atmosphere and scorching Earth. After this transformation, our Sun will be known as a red giant.

No!the sunlight is a celebrity and prefer each and every stars is split into 3.the helium middle,the interface and the hydrogen envelope.because the movie star grows older it is going to change right into a red significant and at this degree the hydrogen burning takes position genuinely on the interface then finally the hydrogen burning subsides interior the middle.because the mass of the sunlight is large(4.39*10^27 much) gravitational forces start up to settlement the middle,the density of the the helium middle will advance andthe temperature rises .if the sunlight's middle starts burning its helium it ought to take tens of millions of years yet finally an implosion ought to take position -that signifies that the sunlight's middle collapses and the completed sunlight explodes in a significant zap in a stellar adventure common as a supernova.if no longer nicely it ought to easily dissolve and delivers up shining....

No. The sun shines because of energy released when hydrogen atoms are fused together into helium, giving off energy. When the sun has no more hydrogen to fuse into helium, it will stop giving off energy and therefore stop shining. This will happen in a few billion years

Nope scientists give it a couple million years before it explodes turning into a black hole and sucking in all the planets surrounding it.....I think I wasnt paying that much attention in science when we went over it...

no
its due to cool down in about billions of years
people say it supposed to explode but that is absolutely not true!
the fact is, our sun isn't big enough to hold that immense power and explode into a black hole. ours will simply coll out

listen to the first answer by astro....there was a special on this on the national geographic channel....when it does burn out like he/she said. in 13 billion or so years...it does become a red giant....becomin as big as earths orbit....and hence...we all are cooked......funny thing is this is my boss' biggest fear lol

Several million years.

No. Eventually it will become a red giant and explode, possibly becoming a black hole.
