Earth's people are struggling with dangers such as climate change, but five million years later, all of that will not matter. The Sun's life cycle began about 4.6 billion years ago, and on a rough estimate of 4.5 to 5.5 billion years, the Sun will begin to reduce its supply of hydrogen and helium and will enter a phase known as Red Giant Branch (RGB) is known to grow and spread more than its current size and end up devouring the earth.
Everything and everyone on the surface of the earth will die. Perhaps only one that could survive this inferno will be the rocky core of our planet that could orbit the dead and cold remnants of the sun.
Later, when the sun reaches its end, it is believed that its outer layers do strike. And in the end, it will be a white dwarf. So far, astronomers have not realized how this will happen and whether or not the sun will end up as a planetary nebula. However, a team of international astronomers has proven that the sun will end its life cycle by transforming itself into a huge ring of interstellar gas and dust, known as planetary nebulae.
The researchers had a foretaste of our inevitable fate, L2 Puppis, which was billions of years ago five years ago and probably liked the sun. According to a professor named Albert Ailjsta, when a death of the star occurs, it ejects mass of gas and dust known as its shell in space. The mass of the shell can be as large as half the mass of the star. This reveals the core of the star that runs out at the end of the Star's life at this point, before finally dying.
At this very point, the hot center lets the ejected envelope shine for about 10,000 glittering years – a short time in astronomy. This is the thing that makes the planet cloud visible.
"When a star dies, it ejects a mass of gas and dust – known as its shell – into space, which can be as much as half the mass of the star, revealing the core of the star, the At the time of the Star's life, it runs out of fuel, eventually leaves and eventually dies, "said Professor Albert Zijlstra of Manchester University.
Prof. Albert Zijlstra of the University of Manchester, who was part of the international group of researchers, said that when the stars die, they eject a huge mass of dust and gas into space, which is called their shell. The professor further said that the envelope could measure about half the mass of the original star. He further said that this reveals the core of the star, which in this scenario is gradually depleted in the life of the star before it finally dies. Zijlstra further said that only then does the flaming core shine brilliantly on the ejected shell for some ten thousand years. Zijlstra added that this is the reason for the visibility of the "planetary nebula" and some of them are so brilliant that they could be observed from great distances.
"We found that stars with a mass less than 1.1 times the mass of the planetary nebula The sun produces a weaker nebula and stars that are more massive than 3 solar masses, lighter nebulae, but for the rest is the predicted brightness very close to what was observed. Problem solved, after 25 years! "Said Professor Zijlstra.
Earlier studies have shown that our sun explodes before death. Stars are enormous amounts of hydrogen, and when they burn their resources, they contract and become remarkably hot. The outer layer of the star then expands when it comes into contact with the burning central nucleus, and describes why stars grow when they age to red giants. The process of expansion continues and causes it to reach its original size hundreds of times, but with a thinner density.
As the aging process begins, the "convection cells" on the surface of a star change. These are necessarily stores of liquid that are held in place by the movement of heat. Upon definition of the convection, the cooling liquid moves down from the edges as the hot liquid moves toward the center of each spot, causing the liquid to be suspended in bubbles on the surface.
As the sun radiates its outer layers over tens of thousands of years, creating a mist that will boil liquid on earth, especially in the form of oceans, seals the atmosphere with nitrogen and carbon dioxide. As a consequence, life on Earth will cease to exist even before the solar blast destroys the entire solar system.
Will there still be an individual on Earth's surface who will oppose this?
In 2013, according to a study by the University of East Angila Long before the Sun spreads, all life on Earth's surface is likely to die out. We estimate that the earth is no longer worth living between 1.75 and 3.25 billion years ago. After this point, the earth will be in the hot zone of the sun, all oceans will evaporate and we will see a catastrophic and final annihilation of all life.
