HD 140283, informally nicknamed Methuselah star is a ...subgiant star about 190 light years away from the Earth ...estimate an age for the star of 14.46 ± 0.8 billion years. Due to the uncertainty in the value, this age for the star does not conflict with the age of the Universe , 13.798 ± 0.037. ...., the star must have formed soon after the Big Bang SMSS J031300.36-670839.3 (abbreviated to SM0313) is a star in the Milky Way at the distance of 6000 light years from Earth. With an age of approximately 13.6 billion years, it is the oldest known star in the Universe. The star formed only about 100 million years after BB found six star forming galaxies about 13.2 billion light years away and therefore created when the universe was only 500 million years old. Here http://en.wikipedia.org/wiki/Chronology_of_the_universe#mediaviewer/File:CMB_Timeline300_no_WMAP.jpg it is said that first stars appeared 400,000 year after BB, - is HD (and SMSS) an exception, how can HD have formed soon after (if not before!) BB, and most of all - how can it be only 190 ly away, when star formed after 500,000 y are 13.2 G ly away? - why is its redshift not known?
