Astronomers have found one of the oldest stars in the Milky Way and possibly one of the oldest in the universe, a body made up almost entirely of elements generated in the Big Bang birth of the cosmos.
The tiny, 13.5-billion-year-old star is part of the Milky Way’s “thin disk,” the realm where the sun resides. Given the age of the newly discovered star, the solar system’s neighbourhood may be up to three billion years older than previously thought.
This is the problem I have. Read a bit of this which says it is only about 1,950 ly (600 pc) fron Earth. How come this star is in the Milky Way. Why is it still around, if we think there was a Big Bang around 14 billion years ago? It should have gone beyond it's 'eat by date' has gone? And why don't it have a red-shift, indicating it is flying away from us?
