原文:
The combined light of stars along the Milky Way are reflected by these cosmic dust clouds that soar some 300 light-years or so above the plane of our galaxy. Dubbed the Angel Nebula, the faint apparition is part of an expansive complex of dim and relatively unexplored, diffuse molecular clouds. Commonly found at high galactic latitudes, the dusty galactic cirrus can be traced over large regions toward the North and South Galactic poles. Along with the refection of starlight, studies indicate the dust clouds produce a faint reddish luminescence, as interstellar dust grains convert invisible ultraviolet radiation to visible red light. Also capturing nearby Milky Way stars and an array of distant background galaxies, the deep, wide-field 3×5 degree image spans about 10 Full Moons across planet Earth’s sky toward the constellation Ursa Major.

🌌🙌 在我們的星空中，有一個名為 Angel Nebula 的奇幻現象，這些銀河中的塵埃雲反射著恆星的微光，它們的高度約為 300 光年，遠高於我們銀河系的平面。這些神秘的塵埃雲屬於一個廣闊而相對未被探索的稀疏分子雲複合體，通常分布於高銀河緯度。
這些星際塵埃不僅反射星光，還會散發出微弱的紅色光輝，因為塵埃顆粒將不可見的紫外線輻射轉換為可見的紅光。透過絢麗的圖像，我們得以欣賞周圍的銀河恆星及一系列遙遠的背景星系。整幅深邃的寬視野圖像跨越大約 10 個滿月的範圍，直指大熊座（Ursa Major）的方向。
