will the sun burnout??

Question

will the sun stop radiatin all kinda radiation(includin light)?? i mean will the sun vanish completely?? wht will happen then?? will the life forms in earth survive it?? will humans survive it?will it affect marine life forms??

Answer 1

Yes, the sun will burnout. It is using hydrogen as a nuclear fusion fuel and will run out of it in about 5 billion years. At that time, the hydrogen in the Sun's core will be gone, the outer layers will expand and the Sun will become a red giant. It will continue burning hydrogen (and hellium) from these outer layers for about 1 billion years. Then all the fuel will be gone and what has left form the sun will collapse to form a white dwarf. The white dwarf won't have fuel to burn, but it will be initially very hot, so it will emit radiation for many millions of years before it cools down.

I believe by that time life forms on Earth will be advanced enough to survive in one way or another, including the ancestors of humans. In fact, life forms will be affected by the Sun much earlier. In a 100 million years, the Sun will become hot enough to accelerate hydrogen molecules in the Earth's atmosphere enough so that they leave the planet. This would eventually lead to the evaporation of the oceans (affecting marine life) and all other water. However, by that time, human ancestors or other life forms should have the knowledge and ability to prevent this from happening (moving Earth further away from the Sun, building a protective shield, etc.)

Thank you!

Answer 2

The sun is not likely to just vanish. It will live it's life like other stars, it will grow in size mass volume diameter and will grow much hotter then the mid life star we have today. Scientists be live that the sun will last for another 5 billions years. No one knows for sure, but it is possible for the sun to grow so big in it's later years, that it will swallow the first four planets in our solar system. Then it explode, then leaving possibly another star or a black hole. Ether way, live forms wont likely be on the planet once the sun reaches this state in its growing process, i mean the human body can only take so much.

Answer 3

In a way it will yes. Nothing on Earth will survive it because the Sun will expand and will swallow up the first four planets as it becomes a red giant. The its outer layers blow off and form a planetary nebula. Then the Sun colapses and becomes a white dwarf. By then all the planets will be gone. Don't worry this wont happen for billions of years.

Answer 4

In its current stage of life, our Sun is turning hydrogen into helium through nuclear fusion at the rate of hundreds of billions of tons a day. When the hydrogen is used up, the sun will go from yellow star phase into red giant phase and turn helium into heavier elements. At that point, its surface will be somewhere between the orbits of earth and Mars. Yes, Mercury, Venus, and earth will all have been vaporized. Eventually, when the heavier element fuel is used up, the remaining matter will collapse due to gravity and our sun will end up as a cooling white dwarf star. But, since this isn't going to happen for at least a few billion years, hopefully we will have figured out away to move to a different planet to enjoy the show.

Answer 5

To answer your first question---yes the Sun will eventually burn out. It's whats called a Dwarf star which in comparison to other stars, it's a baby. By the time burnout comes around it will be a Supernova and not much in our solar system will survive the intense heat that will be produced. Earth will look much like Mercury by then.

Answer 6

well yeah after around million years the sun won't have hydrogen to burn then it will start burning helium and it start to grow,and consume the first four planets including Earth, burning land and boiling oceans.It will go on like this for another million years.It will become almost as small as the moon and weigh around 16 tonnes and then it will die. Not vanish but it'll look like a ball of ash.

Answer 7

Right now it is in its middle ages. It still has enough and more than enought hydrogen, helium and othere combustable gases. the sun will eventually burn out but not till millions of years. when sun will come to its last stage, it will creat a highly dangerous explosion called supernova explosion.It is even danger than a nuclear bomb explosion. The exploision it self will emit the light for years and years.

Answer 8

Astronomers believe that the Sun is midway through its life. In 5 billion years, it will die out. In the process, it will expand outwards and is supposed to swallow at least the first three planets going out from the Sun.

Answer 9

Yes, our star will "burn out". Our star is a Solar Mass star and thus has a shelf life of 10 billion years. Our star is currently middle aged. So, have no fear, we have another 5 billions years or so before it goes to nova.

Answer 10

the sun is a mass of incandescent gas, a gigantic nuclear furnace where hydrogen is built into helium at a temperature of millions of degrees.
