ALMA Directly Detects Star-Forming Gas in Early Galaxies
Scientists have announced the first direct detection of star-forming gas within early galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA). This breakthrough provides new insights into how galaxies began to form roughly a million years after the Big Bang. The ability to directly trace the neutral component of this cold gas is crucial for understanding how stars emerged and gradually built the cosmic structures observed today.
The Atacama Large Millimeter/submillimeter Array (ALMA) has achieved the first direct detection of star-forming gas in early galaxies.
These initial galaxies began to emerge approximately a million years after the Big Bang. Within these nascent systems, stars formed from expansive reservoirs of cold gas, a process that progressively constructed the cosmic structures visible today.
Understanding this star-forming gas is considered vital for explaining the growth and evolution of galaxies. Directly tracing the neutral component of this gas has previously posed a significant challenge, particularly when observing at great distances.
