Astronomers have discovered a massive hidden fuel source in a young galaxy cluster.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), they found a vast amount of molecular gas in a protocluster named SPT2349-56.
This extra gas was previously hidden and forms a massive, spread-out reservoir surrounding the cluster.
The presence of this hidden gas suggests that stars will continue forming in SPT2349-56 for more than 400 million years, challenging existing models of galaxy formation.
