Metal-Free Stars

Using the James Webb Space Telescope (JWST), a team of 15 astronomers discovered a galaxy (RXJ2129-z8HeII) with a measured redshift that corresponds to a distance of 13.16 billion light-years. This measurement implies that astronomers are seeing it just 630 million years after the big bang creation event. The newly discovered galaxy’s features include two unique features: a bright ultraviolet continuum with an extremely steep spectral slope and a strong helium emission line. These newly found features, combined with a discovery made a few months earlier of an ionized gas cloud in the halo of another galaxy that contains only hydrogen and helium, affirms a fundamental prediction of the biblically predicted big bang creation model. That prediction claims that before any stars form the elemental composition of the universe will, by mass, be composed of 75.33% hydrogen, 24.67% helium, and a trace amount of lithium. These discoveries provide yet more evidence that the more we learn about the universe, the more evidence we accumulate that a God beyond space and time created the universe and exquisitely designed it so that humans could live and thrive.
