如果玫瑰星雲換個名字,看起來會這麼甜美嗎?NGC 2237 這個平淡無奇的新總表命名似乎並沒有削弱這個花團錦簇的發射星雲的外觀,它是由智利國家科學基金會塞羅託洛洛美洲天文臺布蘭科 4 米望遠鏡上的暗能量相機(DECam)拍攝的。 星雲內部有一個由明亮的年輕恆星組成的開放星團,命名為 NGC 2244 。這些恆星形成於大約 400 萬年前的星雲物質中,它們的恆星風正在清除星雲中心的一個洞,這個洞被一層塵埃和熱氣體隔絕開來。來自熱星團恆星的紫外線使周圍的星雲發光。玫瑰星雲的寬度約為 100 光年,位於大約 5000 光年之外,用小型望遠鏡可以看到獨角獸(Monoceros)星座的方向。 開放科學:瀏覽天體物理學原始碼庫中的 3 , 700 多個程式碼
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).
