[漢羅] 袚鍊星雲 ê 噴流

是啥物天體會掛這條袚鍊星雲？ 較早 ê 分析表示，這條袚鍊 是 行星形星雲，是 恆星 行到伊性命上尾 ê 坎站噴出來 ê 氣體雲。 而且，tī 袚鍊面頂彼幾粒 璇石，其實是發光氣體結 ê 光 丸。 Tī 袚鍊星雲中心應該是有 兩粒恆星 leh 互相轉踅。 毋閣 in 兩粒 近到 合用仝一个大氣層，才會 tī 哈伯太空望遠鏡 翕著 ê 這張影像 內底，叫是講 in 干焦一粒爾爾。 倒爿頂懸 kah 正爿下跤 ê 紅光氣體雲，是 ùi 星雲中心噴出 ê 噴流 造成 ê 產物。 明亮 ê 噴流到底是當時、是按怎形成 ê？To̍h 變做是一个 研究 ê 主題 矣！ 這个袚鍊星雲干焦 5000 歲爾爾，伊 ê 大細有 5 光年 闊，而且會當用 大台望遠鏡 ùi 天箭座 ê 方向揣著。

[English] Jets from the Necklace Nebula

What celestial body wears the Necklace Nebula? First, analyses indicate that the Necklace is a planetary nebula, a gas cloud emitted by a star toward the end of its life. Also, what appears to be diamonds in the Necklace are actually bright knots of glowing gas. In the center of the Necklace Nebula are likely two stars orbiting so close together that they share a common atmosphere and appear as one in the featured image by the Hubble Space Telescope. The red-glowing gas clouds on the upper left and lower right are the results of jets from the center. Exactly when and how the bright jets formed remains a topic of research. The Necklace Nebula is only about 5,000 years old, spans about 5 light years, and can best be found with a large telescope toward the direction of the constellation of the Arrow (Sagitta).
