从我们在银河系的有利位置，我们正面看到了NGC 1232。这个巨大而美丽的螺旋星系直径近20万光年，位于距离我们4700万光年远的南方飞毛座。这张清晰的、多色的、望远镜拍摄的NGC 1232图像包含了遥远的宇宙岛屿的非凡细节。从核心向外，星系的颜色从中心老恒星发出的黄光转变为年轻的蓝色星团和沿着巨大的旋臂形成的红色恒星区域。NGC 1232的小的、barbar螺旋的伴星星系被编目为NGC 1232A。据距离估计，它离我们远得多，大约有3亿光年远，不太可能与NGC 1232相互作用。当然，这颗尖尖的明亮恒星比NGC 1232要近得多，而且位于我们的银河系内。

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.
