So our sun will die and it's scary



  Scientists Unveil a Massive Shady and Knotted Sunspot Center Twice the Width of the Earth

Imagine how the ultimate source of energy on Earth – the Sun – will find its end? An international group of astronomers have claimed to have figured out when the sun would die and what would eventually happen. According to the experts, the sun would end in flames of glory, called a "planetary nebula."

As the study shows, if the sun burned its last hydrogen, the sun would become a large red mass and increase about 250 times its size today. This would certainly destroy the earth, which until then could have become uninhabitable. The experts say this process would leave a spectral burning band of interstellar dust and gas.

Almost ninety percent of all stars end up as planetary nebulae that become red giants. In the past people thought that the sun was too small and did not have the mass needed to build one. According to new research, the sun is just big enough to show this activity.

Researchers have developed a completely new data model to achieve these results. The model predicts the life process of the stars with different masses. It even foresees the brilliance of the large substance shell that the stars emit when their lives end. Remarkably, this huge shell can make up nearly half of the mass of the star.

As shown, these giant envelopes have the ability to shine brilliantly for nearly 10,000 years and are even visible from a few "millions of light" years ago. "It's basically the energy of the left-behind stellar nucleus that lets this happen, as its emitted ultraviolet radiation ionizes the ejected material."

"When a star dies, it ejects a mass of gas and dust – known as its shell – into space. The shell can be as much as half the mass of the star. This reveals the core of the star, which at this point in the life of the star has run out of fuel, eventually leaves and eventually dies, "said Professor Albert Zijlstra of the University of Manchester.

Professor Albert Zijlstra of the University of Manchester, Among the international researchers said, when the stars die, they push a huge amount of dust and gas into the room called the envelope, the professor said that the envelope could measure about half the mass of the original star He 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 about ten thousand years added that this is the reason for the visibility of the "planetary nebula" and some of them are so brilliant ant 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.
