Hidden cosmic fuel tank found in infant galaxy cluster

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), along with complementary data from the Atacama Pathfinder Experiment (APEX), have discovered a surprisingly large reservoir of molecular gas in a protocluster of galaxies known as SPT2349-56. This protocluster, located approximately 12 billion light-years away, is a region of the early universe where a cluster of galaxies is just beginning to form.
