The Future Of The Sun | What will Happen To The Sun In Future | The Future Of A Star Visit https://goo.gl/KXjBhO to know more about this Inside every newborn star hydrogen atoms are fused together to make helium This process is called fusion, and it creates the energy of every star. What happens to a star during the rest of its life depends on how massive it is at its birth. A star like the sun is in a delicate balance between gravity which wants to make the star collapse in on itself and the pressure that pushes outward that comes from the energy produced in these fusion reactions at its core At some point in the future, the hydrogen runs out. At that point, the core of the star will start to collapse in on itself under its own weight it gets denser, it gets hotter until the point where you can actually start to use the helium atoms themselves as the fuel for the fusion pushing helium atoms together, making carbon and oxygen the next heavier elements on the periodic table As the star begins to fuse helium, it creates more energy and that causes the outer layers of the star to expand One day, our sun will grow so large it will swallow up the inner planets of the solar system out as far as the Earth! It will become a red giant. For the sun, this will be the beginning of the end What happens is that the outer layers of the star get farther and farther from the middle The force of gravity that they feel is getting weaker. And, actually, the star loses hold of its outer atmosphere. Its outer atmosphere drifts off out into space. It expands to become a planetary nebula. And they're some of the most beautiful objects in the universe. Once the outer layers have drifted away, all that is left of the star is its core A white dwarf star is the dead, remnant core of a star like the sun at the end of its life It's something that might weight as much as 1/2 the mass of the sun but it's only about the size of the Earth, so it's an incredibly dense object. It's dead, there's no nuclear fusion going on any more, it's incredibly hot but then over millions of years, it will gradually cool down to become a black dwarf Some stars, however, are much more massive than the sun and they lead very different lives. They are able to fuse heavier and heavier elements inside their core the star gets bigger and bigger some grow up to 1000 times the size of our sun until it has fused elements all the way up to iron and once we've formed an iron core, there's no more energy that can be got from fusion that core collapses the rest of the star starts to collapse in after it but then it bounces off. There's a huge shock wave And in just a second: BANG! The outer parts of the star are blasted off in to space in a huge super-nova explosion!These super-nova explosions are so powerful that when one of these stars explodes it can actually outshine the whole galaxy of which is part (a galaxy of maybe a 100,000 million stars). For these super giant stars all that is left is a super dense core known as a neutron star an object that can have a mass greater than our sun but be less than 20 kilometers across but for the most massive stars of all we think, that when the core collapses the gravity is so strong, it becomes a black hole from which not even light can escape so stars are actually the places in the universe where the elements are created after the Big Bang, our universe contained only hydrogen and helium. All the other, heavier elements were therefore fused inside stars. ======================================================= Read more facts and information about space and planet at http://factsandtrivia.co.in/space/ Read Interesting facts about planet Earth
