自由女神像星云里发生了什么？明亮的恒星和有趣的分子正在形成和释放。这个复杂的星云位于被称为RCW 57的恒星形成区域，除了标志性的纪念碑外，对一些人来说，它看起来像一个飞行的超级英雄或哭泣的天使。通过数字移除恒星，这张重新分配的彩色图像展示了黑暗星际尘埃的密集结，被这些恒星电离的发光氢气场，以及垂死恒星排出的巨大气体环。对NGC 3576（也被称为NGC 3582和NGC 3584）的详细研究发现，至少有33颗大质量恒星处于形成的最后阶段，并且明显存在被称为多环芳烃（PAHs）的复杂碳分子。多环芳烃被认为是在恒星形成区域的冷却气体中产生的，它们在50亿年前太阳形成星云中的发展可能是地球上生命发展的重要一步。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

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.
