距离我们大约7000万光年远，美丽的螺旋星系NGC 289比我们的银河系还要大。从近正面看，它明亮的核心和彩色的中央圆盘让位于非常暗淡的蓝色旋臂。广阔的旋臂从星系中心扫过10万光年。在这张清晰的望远镜星系图像的右下方，主螺旋臂似乎遇到了一个小而模糊的椭圆伴星系，与巨大的NGC 289相互作用。当然，尖尖的恒星是在前景的场景。它们位于银河系南面的雕刻家星座。

About 70 million light-years distant, gorgeous spiral galaxy NGC 289 is larger than our own Milky Way. Seen nearly face-on, its bright core and colorful central disk give way to remarkably faint, bluish spiral arms. The extensive arms sweep well over 100 thousand light-years from the galaxy's center. At the lower right in this sharp, telescopic galaxy portrait the main spiral arm seems to encounter a small, fuzzy elliptical companion galaxy interacting with enormous NGC 289. Of course spiky stars are in the foreground of the scene. They lie within the Milky Way toward the southern constellation Sculptor.
