[漢羅] LDN 1622：惡魔星雲

對一寡人來講，這个烏暗 ê 形體看起來就親像是神話內底 ê 惡魔。 科學上來講，Lynds 烏暗星雲 (LDN) 1622 ê 背景是足暗 ê 發光水素氣體，愛用望遠鏡 tùi 這區長時間感光 才看會著。 相對來講，tī 這張影像 中央倚正爿頂懸 彼个較光 ê 反射星雲 vdB 62，是較好揣。 LDN 1622 是 tī 咱銀河盤附近、倚 Barnard 環 ê 天區。 Barnard 環是一个大型雲箍仔，踅 tī 獵戶座皮帶 kah 獵戶座 寶劍外圍。 這區是一个豐富閣 複雜 ê 發射星雲。 照 LDN 1622 閘光 ê 塗粉 外形來看，in 應該是 tī 仝款遠 ê 所在，差不多有 1500 光年 遠。 若是按呢，這 2 度 闊 ê 視野差不多有 60 光年闊。 少年恆星 就 藏 tī 這片烏暗雲後壁，毋過咱會當用 Spitzer 太空望遠鏡 翕–ê 紅外線 影像 看著 in。

[English] LDN 1622: The Boogeyman Nebula

To some, the dark shape looks like a mythical boogeyman. Scientifically, Lynds’ Dark Nebula LDN 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. In contrast, the brighter reflection nebula vdB 62 is more easily seen just above and to the right of center in the featured image. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard’s Loop, a large cloud surrounding the Lynds 烏暗星雲rich complex of emission nebulae found in the Belt and Sword of Orion. With swept-back outlines, the obscuring dust of LDN 1622 is thought to lie at a similar distance, perhaps 1,500 light-years away. At that distance, this 2-degree wide field of view would span about 60 light-years. Young stars do lie hidden within the dark expanse and have been revealed in Spitzer Space Telescope infrared images.
