你知道宇宙中有些地方可以看到發光的氣體雲嗎？這些雲叫做星雲！在遙遠的星系中，有些星雲會閃閃發光，這讓天文學家和拍攝宇宙照片的朋友們可以找到它們哦。有一個叫做NGC 55的星系，它就像我們的銀河系有一個光彩奪目的星雲！天文學家使用了50小時呢，拍攝了這幅美麗的圖像，顯示了氫氣（紅色）和氧氣（藍色）在星系中的發光。NGC 55有個可愛的綽號叫做“珍珠串星系”，它就像是我們的衛星星系——大麥哲倫星雲（Large Magellanic Cloud），但NGC 55可是更遠的一顆星系呢，大約有650萬光年那麼遠！在這幅圖片裡，我們可以看到很多小星雲在星系的塵埃中，也可以看到有些在星系的上面，這讓我們更清楚地觀察到遠處正在形成的新星星！
原文:
Can you see nebulas in other galaxies? Yes, some nebulas shine brightly enough — if you know how to look. Clouds of hydrogen and oxygen emit light at very specific colors, and by isolating them, astronomers and astrophotographers can reveal structures that would otherwise be too faint to notice. This deep, 50-hour exposure highlights glowing hydrogen (red) and oxygen (blue) across galaxy NGC 55, viewed nearly edge-on. Also known as the String of Pearls Galaxy, NGC 55 is often compared to our Milky Way’s satellite galaxy the Large Magellanic Cloud (LMC), although NGC 55 lies much farther away at about 6.5 million light-years. The resulting image uncovers a sprinkling of emission nebulas within and sometimes above the galaxy’s dusty disk, offering a detailed look at distant star-forming regions.
