[漢羅] NGC 6995:夜婆星雲
你有看著夜婆星雲無? 伊 to̍h tī 面紗星雲 東半爿 ê 宇宙特寫 出現。 面紗星雲 本身是一个大型超新星殘骸。 這个殘骸是 ùi 大質量 恆星 死亡爆炸 了後,產生 ê 脹大 ê 雲屑仔。 面紗星雲是 圓箍仔形,tī 天鵝座 方向,差不多有 3 度闊。 NGC 6995 私底下嘛叫做 夜婆星雲,干焦半度闊,to̍h 是 月娘 tī 天頂 ê 大細。 面紗星雲離 地球 有 1400 光年遠,用這个距離來估算,伊差不多 是 12 光年闊。 這幅組合影像 ê 影像資料是 ùi 狹頻 濾鏡來的。 超新星殘骸 ê 水素原子 發射線是紅色 ê,酸素 原子 ê 強發射線是藍色 ê。 面紗星雲 ê 西半爿 tī 另外一个 季節 ê 幻影叫做「尪姨 ê 掃帚」星雲。

[English] NGC 6995: The Bat Nebula
Do you see the bat? It haunts this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky toward the constellation of the Swan (Cygnus), NGC 6995, known informally as the Bat Nebula, spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil's estimated distance, a reassuring 1,400 light-years from planet Earth. In the composite of image data recorded through narrow band filters, emission from hydrogen atoms in the remnant is shown in red with strong emission from oxygen atoms shown in hues of blue. Of course, in the western part of the Veil lies another seasonal apparition: the Witch's Broom Nebula.
