這隻宇宙蝙蝠祝你夏季萬聖節快樂！這個中年的萬聖節慶祝活動跨越了兩個半球，儘管北半球是夏天，南半球卻是冬天。與其可怕的氣氛相反，宇宙蝙蝠星雲（Cosmic Bat Nebula，LDN 43）不是與蝙蝠星雲（Bat Nebula，NGC 6995）相混淆的，它是一個生機勃勃的恆星誕生地。一點點年輕的恆星光芒透過由氣體和塵埃組成的濃密雲層，顯露出宇宙蝙蝠長達12光年的翅膀。年輕恆星發出的紫外線光線使得星雲中的氫氣充滿活力，並讓它發出神秘的紅光。從蝙蝠的頭部冒出的發光氫氣噴流，暗示著裡面隱藏著恆星形成的過程。
原文:
This Cosmic Bat wishes you a happy Summerween! This mid-year celebration of Halloween transcends hemispheres, even though summer in the Northern hemisphere is winter in the South. Contrary to its eery aura, the Cosmic Bat Nebula (LDN 43), not to be confused with the Bat Nebula (NGC 6995), is a vibrant birthplace for stars. A bit of young starlight peeks through the dense clouds of gas and dust that make up the Cosmic Bat’s 12 lightyear wingspan. The ultraviolet light from the young stars energizes the nebula’s hydrogen gas, causing it to glow an ominous red. The jet of glowing hydrogen gas emerging from the bat’s head hints at the star formation hidden within.
