[漢羅] WR 134 環形星雲

這張透過 狹頻濾鏡 翕 ê 宇宙速翕，視野範圍差不多是一粒月娘 ê 大細，就 chhāi tī 天鵝座 ê 邊界內底。 相片內底上明顯 ê 部份是這个圓箍仔形星雲 較光 ê 邊緣。 這是離子化 ê 硫磺氣體、水素氣體、kah 酸素氣體 發出 ê 光。 這个複雜 leh 發光 ê 弧形結構，是藏 tī ùi 氣體 kah 塗粉組成 ê 星際雲內底。 這个發光弧其實是氣泡 ê 一部份，嘛會使講是氣體殼 ê 一部份，伊是 Wolf-Rayet 星 WR 134 ê 恆星風 吹出來 ê 結構。 WR 134 就是相片中央 leh 發光彼粒星。 科學家估計 WR 134 差不多是 tī 6000 光年遠 ê 所在，所以這幅圖應該有超過 50 光年闊。 大質量 ê Wolf-Rayet 星 ê 外層氣體殼，會去予能量足強 ê 恆星風 kā 褪掉。 In leh 燒 核燃料 ê 速度是緊甲驚死人。 這款大質量恆星演化到上落尾，會以 壯觀 ê 超新星爆炸做結束。 這个恆星風 kah 上落尾 ê 超新星，會增加星際物質 重元素 ê 成份，這 tùi 做後一代恆星 是有足大 ê 幫贊。

[English] WR 134 Ring Nebula

Made with narrowband filters, this cosmic snapshot covers a field of view about the size of the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the glow of ionized sulfur, hydrogen, and oxygen gas. Embedded in the region's interstellar clouds of gas and dust, the complex, glowing arcs are sections of bubbles or shells of material swept up by the wind from Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away, making the frame over 50 light-years across. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. The stellar winds and final supernovae enrich the interstellar material with heavy elements to be incorporated in future generations of stars.
