An even more interesting possibility, however, is that x-ray flashers come from explosions in even more distant regions of the universe, where cosmic expansion since the Big Bang would have shifted emitted gamma rays into the x-ray range and intergalactic gas blocks visible afterglow, as none of these x-ray flashes have been observed to have a detectable, visible - light afterglow.

As this quasar light travels for as long as billions of years through intergalactic space, it passes through filaments of intergalactic gas which absorb certain colors of the light.

If a distant galaxy were made of antimatter, it would constantly be producing gamma - rays as it encountered the matter in the intergalactic gas clouds that exist throughout galaxy clusters.

«Quasars are massive galaxies, and we expect them to be in the denser parts of the universe, where the density of the intergalactic gas should also be higher,» says Font - Ribera.

In addition, near the galaxy cluster center, intergalactic gas is so hot it can not cool to condense and form stars.

The gravity of the galaxy clusters also gathers up gas and the gas heats up from the friction of the intergalactic gas particles bumping into each other.

High - velocity clouds are vagabond clumps of intergalactic gas, possibly left over from the formation of the Milky Way and other nearby galaxies.

Hubble, being a space - based observatory with state - of - the - art spectrographs, can search for the missing colors of light absorbed by the intergalactic gas, particularly in the high - energy ultraviolet colors where the hot intergalactic gas does a significant amount of absorption.

Hubble found that much of the intergalactic gas in the distant universe was being heated by stars and regions around supermassive black holes to about 10,000 degrees.

Identifying the colors that are missing, or absorbed, in spectra gives astronomers a great deal of information about the intergalactic gas, including its composition and temperature.
