Explanation: When stars form, pandemonium reigns. A textbook case is the star forming region NGC 6559. Visible in the featured image are red glowing emission nebulas of hydrogen, blue reflection nebulas of dust, dark absorption nebulas of dust, and the stars that formed from them. The first massive stars formed from the dense gas will emit energetic light and winds that erode, fragment, and sculpt their birthplace. And then they explode. The resulting morass can be as beautiful as it is complex. After tens of millions of years, the dust boils away, the gas gets swept away, and all that is left is a bare open cluster of stars.

说明: 当恒星形成时，喧嚣混乱主宰一切。恒星形成区NGC 6559就是这样的教科书范例之一。在这幅主题影像里，可见到泛红的氢发射星云、泛蓝的尘埃反射星云、满是尘埃的暗吸收星云、以及它们所诞生的恒星。而从致密气体里诞生的第一批大质量恒星，将会发出高能星光和恒星风，侵蚀、碎裂和雕塑诞生它们的育婴室。接着，它们爆发生了爆炸，所产生的大混乱可以是既美丽又复杂。在数千万年后，其内的尘埃被蒸发掉，气体也被吹走，徒留下一个空泛的疏散星团。
