这只宇宙蝙蝠祝你万圣节快乐！这个年中万圣节的庆祝活动超越了半球，尽管北半球的夏天是南半球的冬天。与它的光环相反，宇宙蝙蝠星云（LDN 43），不要与蝙蝠星云（NGC 6995）混淆，是一个充满活力的恒星诞生地。一些年轻的星光透过稠密的气体云和尘埃云隐约可见，这些气体云和尘埃云构成了宇宙蝙蝠12光年的翼展。年轻恒星发出的紫外线激发了星云中的氢气，使其发出不祥的红色光芒。从蝙蝠头部喷出的炽热氢气暗示了隐藏在其中的恒星形成过程。

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.
