NGC 289: Swirl in the Southern Sky Image Credit & [3]Copyright: [4]Mike Selby Explanation: About 70 million light-years distant, gorgeous spiral galaxy NGC 289 is larger than our [5]own Milky Way. Seen nearly face-on, its bright core and colorful central disk give way to remarkably faint, bluish spiral arms. [6]The extensive arms sweep well over 100 thousand light-years from the galaxy's center. At the lower right in this sharp, [7]telescopic galaxy portrait the main spiral arm seems to [8]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 [9]Sculptor.
