"Breakthrough Discovery: Astronomers Uncover Nearly 100 Ultra-Metal-Poor Galaxies"
Originally Published 2 years ago — by Phys.org
Astronomers using the Dark Energy Spectroscopic Instrument (DESI) have identified 95 new extremely metal-poor galaxies at a low redshift, providing valuable insights into the chemical evolution theories of galaxies and the early stages of their evolution. These galaxies, with metallicity below 0.1 of the solar metallicity, are difficult to observe due to their low masses. The findings suggest that these local extremely metal-poor galaxies could be analogs of primeval high-redshift young galaxies, making them excellent objects for studying the early universe.
