interstellar dust

基本解释

But for other astronomers, interstellar dust is useful in its own right.
但對於其他天文學家而言，星際塵埃自身確是有用的。
The present day interstellar dust is weighed by measuring the intensity and color of emission at longer infrared wavelengths.
至今星際塵埃是通過測量長於紅外線的波長的強度和發光顔色來權衡。
The filaments have widths that suggest they are formed as shockwaves from exploding stars travel through the medium, sweeping up and compressing the interstellar dust and gas.
絲狀塵埃雲的寬度暗示它們是形成自一些通過中等大小正在收縮的星際塵埃和氣躰的恒星然後爆發後的激波而成。

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