在遙遠的星空中，有一個叫做NGC 1055的美麗螺旋星系。它距離我們大約6000萬光年，位於名為Cetus的星座中。當我們用望遠鏡觀察它的時候，會發現這個星系像一個圓圓的碟子，直徑超過10萬光年，還比我們的銀河系大一些哦！在這幅宇宙的畫面中，有五顏六色的星星在前景，這些星星都是屬於我們的銀河系。但在NGC 1055的遙遠星系裡，我們可以看到一些粉紅色的星星區域和年輕的藍色星團，它們好像在星際的塵埃間跳舞。還有一些更遙遠的背景星系，就像小點點星星，讓這幅圖畫更生動。更有趣的是，這個NGC 1055的中心旁邊還有一個像盒子一樣的光環，延伸到星系的上方和下方，裡面有很多細細的結構，這些可能是10億年前被這個大星系吸引過來的星系碎片。這真是一個神秘而美麗的宇宙故事！
原文:
Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But telltale pinkish star forming regions and young blue star clusters are scattered through winding dust lanes along the distant galaxy’s thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a boxy halo that extends far above and below the central bulge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago.
