猎户座星云中的黑色尘埃流来自哪里？猎户座分子云复合体的这一部分，M43，是更著名的M42的邻居，经常被成像但很少被提及。M42，部分位于右上方，包含了许多来自四边形星团的明亮恒星。M43本身就是一个恒星形成区，显示出错综复杂的黑色尘埃流——尽管它实际上主要由发光的氢气组成。整个猎户座区域距离我们大约1600光年远。不透明的可见光，如画般的黑色尘埃是在大质量冷恒星的外层大气中产生的，并被强烈的质子和电子风驱逐。

Where do the dark streams of dust in the Orion Nebula originate? This part of the Orion Molecular Cloud Complex, M43, is the often imaged but rarely mentioned neighbor of the more famous M42. M42, seen in part to the upper right, includes many bright stars from the Trapezium star cluster. M43 is itself a star forming region that displays intricately-laced streams of dark dust -- although it is really composed mostly of glowing hydrogen gas. The entire Orion field is located about 1600 light years away. Opaque to visible light, the picturesque dark dust is created in the outer atmosphere of massive cool stars and expelled by strong outer winds of protons and electrons.
