[漢羅] LDN 673：天鷹座 ê 烏暗雲

天鷹座必巡佇天頂迒過牛郎星附近，伊是 kā 咱密喌喌 ê 銀河盤拆–開 ê 烏暗區。 Kah 銀河暗淡 ê 恆星光 相比，這个奇怪 ê 剪影其實是厚塗粉 ê 分子雲。 這內底有做恆星 ê 原始材料，才有法度做出數千萬粒 ê 恆星。 所以 天文學家 才會踮這个烏暗雲內底，揣看有恆星誕生 ê 線索無。 這个碎糊糊 ê 天鷹座烏暗雲複合體去 hŏng 編做 LDN 673。 這張望遠鏡特寫 差不多是比規粒月娘佇天頂看起來 ê 大細閣較大淡薄仔。 佇這个景色內底，咱較看會著–ê，是 kah 少年恆星 有關 ê 高能量大角度噴流，這內底嘛包括中央正爿頂懸 較細 ê 紅色星雲體 RNO 109，kah 下底 ê Herbig-Haro 天體 HH32。 這个 天鷹座 內底 ê 烏暗雲可能 看起來有小可仔恐怖，毋過 in 其實離咱有 600 光年遠。 踮這个距離，這个視野差不多有 7 光年闊。

[English] LDN 673: Dark Clouds in Aquilla

Part of a dark expanse that splits the crowded plane of our Milky Way galaxy, the Aquila Rift arcs through planet Earth’s skies near bright star Altair. In eerie silhouette against the Milky Way’s faint starlight, its dusty molecular clouds likely contain raw material to form hundreds of thousands of stars and astronomers search the dark clouds for telltale signs of star birth. This telescopic close-up looks toward the region at a fragmented Aquila dark cloud complex identified as LDN 673, stretching across a field of view slightly wider than the full moon. In the scene, visible indications of energetic outflows associated with young stars include the small red tinted nebulosity RNO 109 above and right of center, and Herbig-Haro object HH32 below. These dark clouds in Aquila might look scary, but they’re estimated to be some 600 light-years away. At that distance, this field of view spans about 7 light-years.
