"They serve as collectors for the intergalactic gases, and no doubt condensers also."

It is embedded in intergalactic gas that has a temperature of 10 million degrees.

It also appears to have as many galaxies and as much intergalactic gas as is expected for a cluster of this size.

Meanwhile, the prevailing theories also believe that only the intergalactic gas is free to separate out from both the galaxies and the dark matter, during mergers.

Pink runs an intergalactic gas filling station.

X-ray studies have revealed the presence of large amounts of intergalactic gas known as the intracluster medium.

One piece of observational evidence is the distribution of matter, including galaxies and intergalactic gas, which are observed today.

These absorption lines result from intergalactic gas through which the galaxy or quasar's light has traveled.

But this is definitely a lower limit calculation, and it ignores many possible atom sources such as intergalactic gas.

This ionization of the atoms would make the intergalactic gas largely invisible.
