An artist’s concept of a small red dwarf star is shown above. Determining the ages…. And, if accurate, it would also mean that the star is older than the universe itself—currently estimated to be 13.82 billion years These are recognized as among the oldest: Some of these are among the first stars from reionization (the stellar dawn), ending the Dark Ages (cosmology) about 370,000 years after Big Bang. Above: A full-sky map of the oldest light in the universe.Colors indicate "warmer" (red) and "cooler" (blue) spots. Like all the other galaxies on this list, at the time of its discovery, SXDF-NB1006-2 was the oldest known galaxy in the universe. In 2002, a group of scientists discovered that BD +17° 3248 had gold, marking the first time that gold had been discovered in a star other than our Sun. Called the Methuselah star, HD 140283 is 190.1 light-years away. Caffau said that she was surprised to actually find a star in the “forbidden zone” of the star formation model. Image credit: Space Telescope Science Institute/AAP A team led by astronomers at The Australian National University has discovered the oldest known star … Globular star clusters are some of the most ancient objects in the entire Universe, like Messier 56, above.
