[漢羅] 參宿一 kah 火舌星雲

是啥物 kā 火舌星雲照予光？ Tī 獵戶 座 方向，離咱 1500 光年遠 ê 所在，有一个星雲。 伊發出 ê 光 kah 塗粉 烏帶 tī 倒爿 to̍h 親像一葩燒滾滾 ê 火。 毋閣，這葩火 足緊提著 酸素，並毋是產生這个發光 火舌 ê 原因。 Tī 這幅圖上倒爿彼粒足光 ê 恆星，是 參宿一。 伊是 獵戶座皮帶 siōng 東爿 ê 恆星。 Kah 參宿一無仝，火舌星雲發出高能 ê 光，kā 火舌 內底 ê 電子 ùi 這片水素雲 ê 氣體激發。 若是 電子 kah 離子化 ê 水素 重新複合，to̍h 會產生真濟 ê 色光。 這張 火舌星雲 (NGC 2024）ê 影像是用三種 可見 光 帶 翕 ê。 細節 ê 部份是 長時間 感光 ê 影像，這是 ùi 水素發出 ê 光。 火舌星雲 是 獵戶座分子雲複合體 ê 一部份。 伊是一个恆星形成區，內底閣有彼个有名 ê 馬頭星雲。

[English] Alnitak and the Flame Nebula

What lights up the Flame Nebula? Fifteen hundred light years away towards the constellation of Orion lies a nebula which, from its glow and dark dust lanes, appears, on the left, like a billowing fire. But fire, the rapid acquisition of oxygen, is not what makes this Flame glow. Rather the bright star Alnitak, the easternmost star in the Belt of Orion visible on the far left, shines energetic light into the Flame that knocks electrons away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electrons and ionized hydrogen recombine. The featured picture of the Flame Nebula (NGC 2024) was taken across three visible color bands with detail added by a long duration exposure taken in light emitted only by hydrogen. The Flame Nebula is part of the Orion Molecular Cloud Complex, a star-forming region that includes the famous Horsehead Nebula.
