NGC 6302: The Butterfly Nebula

地球夜空中明亮的星團和星雲經常被冠以花朵或昆蟲的名字，而它的翼展長達 3 光年的 NGC 6302 也不例外。據估計，該行星狀星雲的中心恆星表面溫度約為 25 萬攝氏度，正在向白矮星轉變，變得異常炙熱，在紫外線下閃閃發光。這顆中心恆星被塵埃環遮擋住了，無法直接看到，但它發出的高能紫外線使星雲中的原子發生了電離。在這張利用窄帶影像資料繪製的清晰望遠鏡檢視中，電離的氫原子和雙電離的氧原子呈現出特有的紅色和藍綠色調，揭示了星雲翼狀雙極外流中令人驚歎的結和絲的複雜結構。NGC 6302 位於約 4000 光年外的天蠍座（Scorpius）。
原文：The bright clusters and nebulae of planet Earth's night sky are often given the names of flowers or insects, and its whopping 3 light-year wingspan, NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the central star of the planetary nebula is transforming into a white dwarf star, becoming exceptionally hot, and shining brightly in ultraviolet light. The central star is hidden from direct view by a torus of dust, but its energetic ultraviolet light ionizes atoms in the nebula. In this sharp, telescopic view composed with narrowband image data, the ionized hydrogen and doubly ionized oxygen atoms are shown in their characteristic red and blue-green hues to reveal a stunning complex of knots and filaments within the nebula's wing-like bipolar outflows. NGC 6302 lies about 4,000 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius).
