The astronomers looked for signs of carbon monoxide, which is present in the universe wherever there is cold hydrogen gas.

The cold hydrogen gas map was superimposed on a map of the cluster's hot gas, which was generated using observations from NASA's Chandra X-ray Observatory.

Cold hydrogen gas is the raw material for forming stars and is plentiful in most galaxies.

One key source of these emissions are extraordinarily feeble signals from the cold hydrogen gas that dominated the cosmos during the so - called Dark Ages of the universe.
