中文翻譯:
在宇宙中，有一片美麗的星雲叫做Rosette Nebula（玫瑰星雲），它的名字雖然有些普通，卻一點也不影響它的耀眼美麗。這片星雲是由美國國家科學基金會的Cerro Tololo國際天文台的Blanco 4米望遠鏡上的Dark Energy Camera（暗能量相機）拍攝的。星雲裡面還藏著一個明亮的年輕恆星團，名叫NGC 2244，這些恆星在大約四百萬年前形成，是從星雲中的物質做成的。這些恆星的星風正在清空星雲中心的區域，周圍被一層塵埃和熱氣所保護。熱恆星發出的紫外線光線讓周圍的星雲發出燦爛的光芒。玫瑰星雲的直徑約有100光年，距離我們大約5000光年，而在小望遠鏡的幫助下，我們可以在獨角獸座（Monoceros）的方向看到它哦！
原文:
Would the Rosette Nebula by any other name look as sweet? The bland New General Catalog designation of NGC 2237 doesn’t appear to diminish the appearance of this flowery emission nebula, as captured by the Dark Energy Camera (DECam) on the Blanco 4-meter telescope at the NSF’s Cerro Tololo Inter-American Observatory in Chile. Inside the nebula lies an open cluster of bright young stars designated NGC 2244. These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula’s center, insulated by a layer of dust and hot gas. Ultraviolet light from the hot cluster stars causes the surrounding nebula to glow. The Rosette Nebula spans about 100 light-years across, lies about 5000 light-years away, and can be seen with a small telescope towards the constellation of the Unicorn (Monoceros).
