researchers tracked the hitherto oldest Sun-like star in the universe. Thus they not only get a sense of how the sun will look like in four billion years ago, but still solve another mystery in cosmology.
Fact our Sun is the best-studied star at all. For 400 years, astronomers observe our Sun with scientific instruments. But while they could learn something about its current state, but little about his past or future. Although there are models of stellar evolution, which allow certain conclusions. However, to validate this, astronomers must study more sun-like stars that are located in other stages of development. Melendez and his colleagues took to the star HIP 102152 18 Scorpii and even targeted. 18 Scorpii was known that he is younger than the Sun, while HIP 102152 was considered older.
