Summary:
- Astronomers have utilized the Atacama Large Millimeter/submillimeter Array (ALMA) to detect neutral atomic carbon in a galaxy existing just 700 million years after the Big Bang, providing critical insights into the early chemical evolution of the universe.
- The detection of this neutral gas serves as a vital tracer for the molecular hydrogen required for star formation, helping researchers understand how the first generations of galaxies transitioned from primordial gas to complex, star-forming systems.
