There's an old-timer in the neighborhood, and it's got a story to tell. A new study of a relatively nearby star shows that it's almost as old as the big bang itself. The star HD 140283 lies about 190 light-years away in the constellation Libra. Astronomers have long known that it's ancient, because it contains mostly hydrogen and helium - which were present at the dawn of the universe - and few of the heavy elements that were forged later in stellar furnaces. With the Hubble Space Telescope, researchers have now pinned down the distance to HD 140283, which allowed them to determine how bright the star is. Along with the chemical ceremonials of the star, the newly derived stellar properties allowed for a new age estimate. The study of HD 140283, in the Astrophysical Journal Letters found that the star is 14.46 billion years old. But the entire universe, as you may have noted heard, is only 13.77 billion years old.
