在廣大的天空中，我們能看到一個叫做安杜拉梅達星系（Andromeda Galaxy）的閃亮星系，這是離我們的銀河星系（Milky Way）最近的大螺旋星系呢！這張圖片中，安杜拉梅達星系的亮亮中心旁邊，有一顆叫做M32的小星系，它就靜靜地在左邊；而另一顆名叫M110的星系則在下面右邊。M32和M110都是小小的橢圓星系，像安杜拉梅達的好朋友一樣！這幅圖片是透過組合60小時的拍攝資料，讓我們能看到安杜拉梅達的美麗螺旋臂上的塵埃帶、年輕的星團和星星正在形成的地方，還有漂浮著的氫氣雲朵，這些都讓我們更加好奇這片神奇的宇宙呢！這些星系距離我們有250萬光年那麼遠，就在宇宙的另一邊！
原文:
This magnificent extragalactic skyscape looks toward the Andromeda Galaxy, the closest large spiral galaxy to the Milky Way. It also accomplishes a Messier catalog trifecta by including Andromeda, cataloged as Messier 31 (M31), along with Messier 32 (M32), and Messier 110 (M110) in the same telescopic field of view. In this frame, M32 is just left of the Andromeda Galaxy’s bright core with M110 below and to the right. M32 and M110 are both elliptical galaxies themselves and satellites of the larger spiral Andromeda. By combining 60 hours of broadband and narrowband image data, the deep telescopic view also reveals tantalizing details of dust lanes, young star clusters, and star-forming regions along Andromeda’s spiral arms, and faint, foreground clouds of glowing hydrogen gas. For now, Andromeda and friends are some 2.5 million light-years from our own large spiral Milky Way.
