Primordial Star

30 December 2012

The title sounds a bit like a Dwardu Cardona book but this story is at www.dailygalaxy.com/my_weblog/2012/12/the-primordial-star-at-the-edge-of… … this subject, has I think, already been posted but here is a different take on the story. The blog writer calls it a primordial star at the outer edge of the Milky Way which should not exist since it lacks the materials cosmologists think necessary for how new stars come to form. This star, it goes on, has the composition that is the nearest that has been found up to now to the Big Bang composition (or theoretical Big Bang composition to be more correct). A low concentration of chemical elements heavier than hydrogen and helium suggests it is the most primitive star ever discovered – yet the exact ration of these elements suggests it is much younger. The relationship between a star's age and its elemental composition stems from the way the early universe evolved. It is thought. As once comment says, the star is normal. It is the consensus theory of star formation that is abnormal.
