interstellar dust

基本解釋

But for other astronomers, interstellar dust is useful in its own right.
但對于其他天文學(xué)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于紅外線的波長的強度和發(fā)光顏色來權(quán)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.
絲狀塵埃云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體的恒星然后爆發(fā)后的激波而成。

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