在幽深的宇宙中，有一個叫做Statue of Liberty nebula（自由女神星雲）的地方，裡面不斷有明亮的星星和有趣的分子形成並被釋放出來。這個神秘的星雲位於名為RCW 57的星際造星區，對一些人來說，它看起來像是飛翔的超級英雄或是一位淚流滿面的天使。這張重新上色的圖片展示了濃密的黑色星際塵埃、閃閃發光的氫氣雲，還有因為恆星的死亡而噴出的氣體。在對NGC 3576（也被叫作NGC 3582和NGC 3584）的詳細研究中，科學家們發現至少有33顆正在形成中的巨大恆星，以及一種叫做多環芳香烴的複雜碳分子（PAHs）。這些PAHs据信是在星際造星區冷卻氣體中形成的，它們的發展可能是五十億年前太陽形成星雲中生命發展的重要一步。

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. 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.
