说明: 确实，万圣节是一个天文节日。然而，天文学家总是乐于在天空中搜寻那些令人毛骨悚然的星系、恒星和星云。这个受欢迎的天体是来自贝弗莉林茨（Beverly Lynds）于1962年编纂暗星云目录中的第43号星云，亲切地被称为宇宙蝙蝠星云。虽然它的外形酷似一只可怕的飞行哺乳动物，但林茨暗星云43的直径横跨超过12光年。这个尘埃星际分子云在发出诡异光芒的同时，内部正在形成恒星，其密度足以在银河系明亮恒星的背景映衬下呈现出剪影般的轮廓。注意，这个宇宙蝙蝠星云距离我们仅有400光年，位于蛇夫座的方向。

英文原文:
Explanation: Sure, Halloween is an astronomy holiday . But astronomers always enjoy scanning the heavens for spook-tacular galaxies , stars, and nebulae. This favorite is item number 43 from the Beverly Lynds 1962 Catalog of Dark Nebulae , fondly known as the Cosmic Bat nebula . While its visage looks alarmingly like a scary flying mammal, Lynds Dark Nebula 43 is over 12 light-years across. Glowing with eerie light, stars are forming within the dusty interstellar molecular cloud that is dense enough to appear in silhouette against a luminous background of Milky Way stars. Watch out . This Cosmic Bat nebula is a mere 400 light-years distant toward the serpent-bearing constellation Ophiucus.
