[漢羅] 闊幅 ê 娘仔殼星雲

星雲當時看起來會親像是掃帚星？ 這个實捅捅 ê 星場 有 2 度闊，伊就佇 天鵝座 內底。 這隻佇天頂飛甲遮爾懸 ê 天鵝，目睭 ê 所在就是娘仔殼星雲。 這个 宇宙娘仔殼 是一个實櫼 ê 恆星形成區，伊是倒爿這个較光 ê 發射星雲 kah 反射星雲。 正爿拖一條長長 ê 星際塗粉雲，予這規个星雲複合體看起來 敢若是一粒彗星。 伊去予編做 IC 5146，星雲中央較光 ê 部份差不多有 10 光年，毋過暗 塗粉 尾溜有 100 光年長。兩个攏離咱有 2500 光年遠。 星雲中心較光 ê 恆星 應該干焦幾若十萬歲 爾爾，伊是予星雲發光 ê 動力來源。 伊嘛 kā 恆星形成 分子雲 內底 ê 塗粉 kah 氣體 put-put--出去，掃出一个閬縫。 雖罔講這條長長厚厚 ê 雲絲 佇 這張 可見光 影像內底 看起來是有較暗，毋過這內底其實是有藏足濟粒 恆星當咧做，而且會當佇 紅外線波段 看著。

[English] Cocoon Nebula Wide Field

When does a nebula look like a comet? In this crowded starfield, covering over two degrees within the high flying constellation of the Swan Cygnus, the eye is drawn to the Cocoon Nebula. A compact star forming region, the cosmic Cocoon punctuates a nebula bright in emission and reflection on the left, with a long trail of interstellar dust clouds to the right, making the entire complex appear a bit like a comet. Cataloged as IC 5146, the central bright head of the nebula spans about 10 light years, while the dark dusty tail spans nearly 100 light years. Both are located about 2,500 light years away. The bright star near the bright nebula's center, likely only a few hundred thousand years old, supplies power to the nebular glow as it helps clear out a cavity in the molecular cloud's star forming dust and gas. The long dusty filaments of the tail, although dark in this visible light image, are themselves hiding stars in the process of formation, stars that can be seen at infrared wavelengths.
