fierce reds and oranges come from vast clouds of ionized hydrogen, set alight by the ultraviolet blast from a young, scorching cluster of massive stars (IC 1590) sitting at the heart of the nebula. Cooler blue-cyan hues trace ionized oxygen, painting the interior like a ghostly lantern. Dark Bok globules — dense knots of dust and gas.
炽烈的红色与橙色源自巨大的电离氢云团，由位于星云中心的年轻、炽热的大质量恒星团（IC 1590）发出的紫外线辐射点燃。较冷的蓝青色则勾勒出电离氧的踪迹，将内部渲染得宛如一盏幽灵般的灯笼。深色的博克球状体——尘埃与气体的高密度结块。
