What surrounds a hotbed of star formation? In the case of the Orion Nebula — dust. The entire Orion field, located about 1600 light years away, is inundated with intricate and picturesque filaments of dust. Opaque to visible light, dust is created in the outer atmosphere of massive cool stars and expelled by a strong outer wind of particles. The Trapezium and other forming star clusters are embedded in the nebula. The intricate filaments of dust surrounding M42 and M43 appear brown in the featured image, while central glowing gas is highlighted in red. Over the next few million years much of Orion’s dust will be slowly destroyed by the very stars now being formed, or dispersed into the Galaxy. Explore the Universe: Random APOD Generator

在星際空間中，熱星形成區的周圍常常被一層神秘的纖細塵埃所包圍。以獵戶星雲（Orion Nebula）為例，這片位於距離地球約1600光年的星際區域，充滿了複雜而美麗的塵埃絲線。這些塵埃對可見光是不透明的，主要是在巨型冷星的外層大氣中形成並被強大的外部粒子風所排放。獵戶星雲中的特拉佩齊烏斯星團（Trapezium）及其他形成中的星團都逸在這片塵埃之中。
在這幅精彩的圖片中，M42和M43周圍的複雜塵埃絲線呈現出棕色，而中央的發光氣體則被強調成紅色。未來幾百萬年間，獵戶星雲的大部分塵埃將會受到這些新生星體的影響而慢慢摧毀或被分散到銀河中。
