[漢羅] Kā 恆星提掉 ê 恆星形成區 NGC 3582

自由女神 星雲是發生啥物代誌？ 遮當咧形成 明亮 ê 恆星 kah 產生 趣味 ê 分子。 這个 tī 恆星形成區內底 ê 複雜星雲 叫做 RCW 57。 伊毋若有成自由女神，嘛有成 咧飛 ê 超人、抑是 咧哭 ê 天使。 用數位處理 ê 方式 kā 相片內底 ê 恆星提掉，閣 重新配色。 內底有展示 烏暗星際塗粉 中足實密 ê 雲丸、去予恆星 kā 水素氣體 離子化 ê 發光氣體、kah 去予死亡恆星噴出來 ê 大型氣體箍仔。 這个 tùi NGC 3576 較細節 ê 研究，包括 NGC 3582 kah NGC 3584，有看著其中 33 粒大質量恆星演化到上尾階段 ê 模樣，嘛確實有揣著複合碳分子，叫做 多環芳烴 (PAHs)。 PAHs 去 hŏng 認為講，伊是 ùi 恆星形成區 內底較冷 ê 氣體製造出來--ê。 而且 PAHs tī 50 億年前 做太陽 ê 星雲 內底出現，tùi 地球 發展性命 來講，是真重要 ê 一步。

[English] Star Forming Region NGC 3582 without Stars

What's happening in the Statue of Liberty nebula? Bright stars and interesting molecules are forming and being liberated. The complex nebula resides in the star forming region called RCW 57, and besides the iconic monument, to some looks like a flying superhero or a weeping angel. By digitally removing the stars, this re-assigned color image showcases dense knots of dark interstellar dust, fields of glowing hydrogen gas ionized by these stars, and great loops of gas expelled by dying stars. A detailed study of NGC 3576, also known as NGC 3582 and NGC 3584, uncovered at least 33 massive stars in the end stages of formation, and the clear presence of the complex carbon molecules known as polycyclic aromatic hydrocarbons (PAHs). PAHs are thought to be created in the cooling gas of star forming regions, and their development in the Sun's formation nebula five billion years ago may have been an important step in the development of life on Earth.
