These galaxies have clouds of cold gas that are giving birth to new stars.

It is most sensitive to very cold gas and dust.

Clouds of dense, cold gas billowed from the machine, then began to settle on the floor.

The low-pressure cold gas is compressed to the high-pressure of the system.

Stars are created within galaxies from a reserve of cold gas that forms into giant molecular clouds.

The probes are filled with very cold gas.

Some very cold gas must be spraying through the hair-fine crack.

More extreme frequency-dependence is visible in the absorption lines of cold gases.

As they rise, colder gases sink toward the core to take their place and in turn become heated.
