銀河系中最令人毛骨悚然的星雲是什麼? LDN 43 就是其中之一,它就像一隻巨大的宇宙蝙蝠,在萬聖節的漆黑夜晚飛舞在群星之間,令人驚歎。 這個分子云位於約 1400 光年外的蛇夫座,其密度不僅足以遮擋背景恆星的光線,還能遮擋附近反射星雲 LBN 7 所照亮的縷縷氣體。 這個由氣體和塵埃組成的長達 12 光年的絲狀物遠非死亡的預兆,它實際上是一個恆星託兒所。 這隻蝙蝠散發著陰森恐怖的光芒,內部被剛剛形成年輕恆星的稠密氣節照亮。 你的天空驚喜你的生日那天,APOD 刊登了哪張照片? ( 1995 年後)
原文:What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background stars, but from wisps of gas lit up by the nearby reflection nebula LBN 7. Far from being a harbinger of death, this 12-light year-long filament of gas and dust is actually a stellar nursery. Glowing with eerie light, the bat is lit up from inside by dense gaseous knots that have just formed young stars. Your Sky Surprise: What picture did APOD feature on your birthday? (post 1995)
