Strange star discovered that is not aging normally
// September 7th, 2012 // Astronomy and Space News
Scientists have discovered a strange star that is not aging normally and seems to remain every youthful. In the picture below, the glowing cluster of stars in the center (known as the “globular cluster”) are all stars that astronomers think formed in the universe’s distant past. Astronomers can determine a star’s age by the presence of chemical elements present in the light they emit. Older stars contain fewer heavier elements (because the universe has not accumulated enough of those yet) and some of the lighter elements deplete over time. The strange star they discovered contains the element lithium, which should have depleted. As the astronomers explained:
The source of this lithium is mysterious. Normally this element is gradually destroyed over the billions of years of a star’s life, but this one star amongst thousands seems to have the secret of eternal youth. It has either somehow managed to retain its original lithium, or it has found a way to enrich itself with freshly made lithium.
Life Science explained the location of the star.
The star is a member of the Messier 4 globular cluster, one of the closest clusters to Earth. The cluster, also known as NGC 6121, lies in the constellation of Scorpius (The Scorpion), and is easily visible to stargazers through binoculars or a small telescope.
