面向 NGC 1232
Facing NGC 1232

從銀河系的有利位置,我們可以看到 NGC 1232 的正面。這個大而美麗的螺旋星系直徑將近 20 萬光年,位於大約 4700 萬光年之外的南鄂裡達諾斯座。NGC 1232 的這幅清晰的多色望遠鏡影像包含了遙遠的島嶼宇宙的非凡細節。從核心向外,星系的顏色從中心老恆星的淡黃色光,變為年輕的藍色星團,以及沿著寬闊的旋臂形成的淡紅色恆星區。NGC 1232 明顯的小型棒狀螺旋伴星系被命名為NGC 1232 A。不過根據距離估算,它的位置要遠得多,大約在 3 億光年之外,不太可能與NGC 1232 發生相互作用。 當然,這顆突出的明亮恆星比NGC 1232 更近,位於我們的銀河系內。
原文:From our vantage point in the Milky Way Galaxy, we see NGC 1232 face-on. Nearly 200,000 light-years across, the big, beautiful spiral galaxy is located some 47 million light-years away in the flowing southern constellation of Eridanus. This sharp, multi-color, telescopic image of NGC 1232 includes remarkable details of the distant island universe. From the core outward, the galaxy's colors change from the yellowish light of old stars in the center to young blue star clusters and reddish star forming regions along the grand, sweeping spiral arms. NGC 1232's apparent, small, barred-spiral companion galaxy is cataloged as NGC 1232A. Distance estimates place it much farther though, around 300 million light-years away, and unlikely to be interacting with NGC 1232. Of course, the prominent bright star with the spiky appearance is much closer than NGC 1232 and lies well within our own Milky Way.
