    Astronomers have hypothesized that what will happen once will inevitably turn off the sun. For months, a team of scientists stared at the star, directly at the jaw of the eventual disappearance of Earth. They left saying: "This is a good result".That's because they came out of the process with a new model to predict the life cycle of the stars. Compared to other more distant stars, the Earth's sun is medium-sized (even among other yellow dwarf stars), which led scientists to wonder if their size would make them behave differently once they die. Using their new model, based on data with updated calculations of the mass of individual stars, the researchers determined that the sun is barely large enough to act in a manner similar to some of the distant stars they have observed in their agony. That is to say, the sun will one day transform dramatically into a brilliant ring of cosmic dust. When medium stars die, they experience a flurry of activity, including a phase of extreme mass loss. That creates a "superwind" effect that pushes large amounts of dust out of the degenerated core of the star, creating a bright, misty ring around its former self. That luminous wrap of dust can be as much as half the mass of the star. The star enters a cooling phase of 10,000 years before disappearing completely. Although it is expected to have a much weaker nebula than the larger stars, Earth's sun is expected to follow the same course, according to a new study published May 7 in the journal Nature Astronomy. The study adds more evidence that supports one side in a long-term debate about the death of stars in the scientific community. For more than 25 years, scientists have disagreed about how bright - if it is - the luminous dust of the sun could be, given its relative size. Many said they believed that it would not be visible at all. The new data suggests that the sun is large enough to emit a bright ring of light.
    "We found that stars with a mass less than 1.1 times the mass of the sun produce a dimmer nebula," said Albert Zijlstra of the University of Manchester in a press release. "This is a good result now we have a way to measure the presence of stars of a few billion years in distant galaxies."Fortunately, humans today have no reason to be anxious for our own sun to die in the short term. It is expected to be around another 10 billion years before it finally succumbs to an inexistence as interstellar dust.
