Extremely metal-poor gas at a redshift of 7
In typical astrophysical environments, the abundance of heavy elements ranges from 0.001 to 2 times the solar value. Lower abundances have been seen in selected stars in the Milky Way's halo(1, 2, 3) and in two quasar absorption systems at redshift z = 3 (ref. 4). These are widely interpreted a...
