The Sun is very likely going through its middle age, revealed a recent study published in June this year by the European Space Agency (ESA), based on observations from the Gaia spacecraft. ESA’s Gaia telescope has revealed information that could help determine when the sun, which formed about 4.57 billion years ago, will die. The study estimated that the sun’s evolutionary process will continue for billions more years before it runs out of fuel and turns into a red giant. The study revealed the sun’s past and future, how the sun will behave in what stage and when it will enter the twilight of its life. What did the ESA study reveal? According to the report released on June 13, 2022, at about 4.57 billion years old, our sun is currently in its “comfortable middle age, fusing hydrogen into helium and generally being rather stable. he still stood.” However, it won’t be the case forever. The sun will eventually die. Information from ESA’s Gaia observatory also revealed its disintegration process. Stellar evolution. ESA “As the hydrogen fuel runs out in its core and changes in the fusion process begin, we expect it to expand into a red giant star, reducing its surface temperature in the process.” Exactly how this happens depends on how much mass a star contains and its chemical composition. To conclude this, astronomer Orlagh Creevey, Observatoire de la Côte d’Azur, France, and colleagues at Gaia’s Coordination Unit 8, and colleagues combed the data for the most precise stellar observations that the spacecraft. “We wanted to have a really clean sample of stars with high-precision measurements,” says Orlagh. When will the sun die? The study found that the sun will reach a maximum temperature around 8 billion years old, before it begins to cool and increase in size. “It will become a red giant star around 10-11 billion years old. The Sun will reach the end of its life after this phase, when it eventually becomes a dim white dwarf.” A white dwarf is a former star that has used up all the hydrogen it once used as its central nuclear fuel and lost its outer layers as a planetary nebula. “If we don’t understand our own Sun — and there’s a lot we don’t know about it — how can we expect to understand all the other stars that make up our wonderful galaxy,” Orlagh said. By identifying stars similar to the sun, but this time with similar ages, the observational gap can be bridged in how much we know about the sun compared to other stars in the universe. To identify these “solar analogs” in the Gaia data, Orlagh and his colleagues looked for stars with temperatures, surface gravities, compositions, masses and radii that are all similar to the present-day Sun. They found 5863 stars matching their criteria. With data from agencies Read here all Latest News, Trending News, Cricket News, Bollywood News, India News and Entertainment News.
