NGC 7635 ：氣泡星雲

NGC 7635: The Bubble Nebula

是什麼造就了這個巨大的太空泡泡？這個誘人的頭狀幻影被一顆恆星的風吹起，編入了 NGC 7635 星系，但也被簡單地稱為 "氣泡星雲"。這幅令人震撼的作品採用了長時間曝光，展現了這個宇宙氣泡及其環境的複雜細節。雖然看起來很精緻，但這個直徑達 10 光年的氣泡提供了暴力過程的證據。從這裡可以看到，在氣泡中心的上方和右側，一顆明亮的熱恆星嵌在星雲的反射塵埃中。這顆恆星的質量可能是太陽的 10 到 20 倍，一股猛烈的恆星風和來自恆星的強烈輻射，將周圍分子云中的高密度物質與發光氣體的結構撞擊在一起。迷人的氣泡星雲位於僅 11000 光年遠的仙后座。您的天空驚喜你的生日那天，APOD 刊登了哪張照片？（ 1995 年後）

原文：What created this huge space bubble? Blown by the wind from a star, this tantalizing, head-like apparition is cataloged as NGC 7635, but known simply as the Bubble Nebula. The featured striking view utilizes a long exposure to reveal the intricate details of this cosmic bubble and its environment. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Seen here above and right of the Bubble's center, a bright hot star is embedded in the nebula's reflecting dust. A fierce stellar wind and intense radiation from the star, which likely has a mass 10 to 20 times that of the Sun, has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation Cassiopeia. Your Sky Surprise: What picture did APOD feature on your birthday? (post 1995)
