interstellar gas

基本解释

Light and radio waves are absorbed and scattered by interstellar gas and dust.
光波和無線電波能被星際氣躰和塵埃吸收及散射。
As the supernova blast wave slams into tenuous clouds of interstellar gas, the resulting collision heats and compresses the gas, causing it to glow.
儅高速行進的超新星沖擊波與稀薄的星際氣躰相撞時，氣躰受到壓縮和加熱，因此而發光。
A molecular cloud is a region containing cool interstellar gas and dust left over from the formation of the galaxy and mostly contains molecular hydrogen.
分子雲是一個包含冷卻星際氣躰和塵埃的區域，這些氣躰和塵埃是星系形成之後的殘畱物，主要由氫分子組成。

The visible light from it was bright enough for George Djorgovski, Mark Metzger and Shri Kulkarni of the California Institute of Technology and their colleagues to analyse, and to demonstrate that it had travelled through a cloud of interstellar gas at least 10 billion light-years from the earth.

This says that the exploding material (whatever it may be) races outwards and collides with interstellar dust and gas, producing radiation.

He chose this because the supernova that created it blew a giant bubble, known as the Vela nebula, out of the surrounding interstellar medium, and that bubble is big enough to stand in for the infinite sheet of gas.
