Stephen Kane was looking for stars that can have planets with warm, tropical climates, which are ideal for life – you know, like Earth – when they saw a little red baby boy named AU Microscopii who is “32 years” away from home .
“The star is a complete baby, or planet. That means we have the opportunity here to see the world as soon as it begins to change, “he said. This enabled them to determine when the planets in our vicinity would collapse within the star. “place of residence”—A distance that is neither too hot nor too cold for life. They found that the star burns brightly at first, then calms down and burns less, so that the mass of life-forms close to the star is about 30 to 40 percent within the star’s first 200 million years. They published their work this month in The Astronomical Journal.
This is important for Kane and other scientists, who hope to one day see a life-loving planet beyond the Earth, with its lush green vegetation, as it suggests that the planet on which humans can live will not exist forever. In the best case scenario, the “Goldilocks”, everything has to be in order, including the temperature that causes the earth to have water on the surface of the earth – a necessity for life as we know it. (Life as we are do not note that another story) Other factors are also important, such as the respiratory rate, stable climate, and adequate protection from ultraviolet radiation. Mars, for example, is in our sun accommodation zone, but its water and air were long gone. Venus it is on the edge of a region, but because of its carbon dioxide cover, it is extremely hot.
The AU Microscopii gives scientists a glimpse of how the galaxy could grow or shrink in a stellar life. “Red stars have a very long history, very bad behavior of young people. It could be hundreds of millions of years before the star is established as an adult,” said Sara Seager, an astronomer at MIT and NASA’s assistant director of planetary research. TESS.
Kane and his team show that since their red star and other stars can act like teenagers for a while, a world without hospitality can be stable along the way. But that change could occur again: “A planet on which human habitation may be present would not have existed before the constellations,” he says.
When the star cools slightly, the earth would be so cold that any ET could get the necessities of life; lakes and rivers will gradually freeze. On the other hand, the oldest stars are often hotter, so that former visitors can see the water that is essential for survival, since everything on earth burns to the point of death.
