你知道獵戶座的哪一部分嗎?在著名的獵戶座星雲北邊,有一個美麗的星際星雲,叫做Running Man Nebula(跑人星雲)。這裡有很多細緻的塵埃,有些因為反射明亮恆星的光而顯得藍色。這個地方的名字源於塵埃中的一部分,看起來像是正在奔跑的腿。這個星雲被編入Sharpless 279,也是獵戶座星座的一部分,更是獵戶分子雲複合體的一員。跑人的明亮恆星,包括42 Orionis,正在慢慢摧毀並改變周圍的塵埃,預計在大約一千萬年後,這些塵埃將會完全消失。這個星雲的大小大約是15光年,距離我們約有1500光年喔!
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
