這是獵戶座的哪個區域？在著名的獵戶星雲正北方向，獵戶座之劍中存在一片風景如畫的恆星形成區，蘊含著大量錯綜複雜的塵埃——其中部分因反射嵌入明亮恆星的光線而呈現藍色。該區域因從特定角度觀測時，棕色塵埃的形狀酷似奔跑的雙腿，故得名"奔跑人星雲"。 這座編號為夏普萊斯 279 的反射星雲，不僅隸屬獵戶座，更是更廣闊的獵戶分子云複合體的一部分。 奔跑人星雲中明亮恆星的光芒——包括距影像中心最近的亮星獵戶座 42 號星——正持續瓦解並重塑周圍塵埃。預計約 1000 萬年後，這些塵埃將徹底消散。該星雲跨度約 15 光年，距離地球約 1500 光年。拼圖星雲：每日天文謎題
原文：What part of Orion is this? Just north of the famous Orion Nebula is a picturesque star forming region in Orion's Sword that contains a lot of intricate dust -- some of which appears blue because it reflects the light of bright embedded stars. The region's popular name is the Running Man Nebula because, looked at from the right, part of the brown dust appears to be running legs. Cataloged as Sharpless 279, the reflection nebula is not only part of the constellation of Orion, but part of the greater Orion molecular cloud complex. Light from the Running Man's bright stars, including 42 Orionis, the bright star closest to the featured image center, is slowly destroying and reshaping the surrounding dust, which will likely be completely gone in about 10 million years. The nebula spans about 15 light years and lies about 1,500 light years away. Jigsaw Nebula: Astronomy Puzzle of the Day
