Nearby Star

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:good] as the big bang itself. The star HD 140283 lies about 190 light-years away in the constellation Libra. Astronomers have [long:short] known that it's ancient, because it [contains:has] mostly hydrogen and helium - which were present at the dawn of the universe - and few of the heavy elements that were [forged:trolled] 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:substances] of the star, the newly derived stellar properties allowed for a new age estimate.
