interstellar dust

基本解释

But for other astronomers, interstellar dust is useful in its own right.
但对于其他天文学家而言，星际尘埃自身确是有用的。
The present day interstellar dust is weighed by measuring the intensity and color of emission at longer infrared wavelengths.
至今星际尘埃是通过测量长于红外线的波长的强度和发光颜色来权衡。
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.
丝状尘埃云的宽度暗示它们是形成自一些通过中等大小正在收缩的星际尘埃和气体的恒星然后爆发后的激波而成。

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