尘埃带

由于外形酷似草帽而得名的“草帽星系”编号为M104，它拥有显著的尘埃带，还有恒星和球状星团组成的明亮星系晕。

Named the Sombrero Galaxy for its hat-like resemblance , M104 features a prominent dust lane and a bright halo of stars and globular clusters .

支持这一观点的证据在这张广角深空照片中清晰可辨，包括旋涡星系特有的暗尘埃带，以及暗淡的恒星和气体漩涡。

Supporting evidence includes the dark dust lanes characteristic of a spiral galaxy , and faint swirls of stars and gas visible in this wide and deep image .

在这张令人难忘的高清彩色图片中，我们可以看到位于棒端和旋臂上那些密集的恒星诞生区，以及横穿星系中央亮核的清晰尘埃带。

This impressively sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms , and details of dust lanes cutting across the galaxy 's bright core .

尘埃粒子所带电荷数越大，磁场对它的影响越明显。

The more charge number the dust grain carries the more obvious the magnetic field effects on it .

它还有助于阻止尘埃和空气所带的其它污染物进入室内。

Also , it helps to prevent dust and other airborne contaminats from flowing into the room .
